This section provides a summary description of the NX Nastran DMAP language, rules, and syntax. A DMAP program consists of a series of functional blocks called “modules,” each of which has a unique name and a specific function. Modules are executed sequentially; branching and looping operations are performed by DMAP control statements. Modules communicate through the NX Nastran Executive System (NES) via logical collections of data called “data blocks” and “parameters.” Data blocks come in two distinct forms: “matrices” that obey the rules of matrix algebra, and “tables” that represent a convenient collection of data items. Data blocks are given arbitrary names (UGS recommends mnemonic names) and have header and trailer information defining their characteristics. Parameters are scalar items used for specifying control, operation, or system characteristics. Modules can use “input parameters,” “output parameters,” or both. Input parameters affect the internal operation of the modules. Output parameters are used to control DMAP logic and/or to pass scalar information to subsequent modules. Data blocks and parameters can be written onto either scratch or permanent physical files. When the normal NX Nastran execution completes, data blocks and parameters written to scratch files are erased, and those written to the permanent physical file are available for future use. The NX Nastran Data Definition Language (NDDL) designates whether a data block is scratch or permanent. A detailed description of the NDDL statements can be found in “NASTRAN Data Definition Language (NDDL)” . NX Nastran provides a variety of prewritten solution sequences. These solution sequences consist of a series of DMAP statements. You can use DMAP to modify these prewritten solution sequences or to write your own solution sequences. The compilation, linkage, and execution of a DMAP program is specified by executive control statements in the input file. The creation of and access to databases is specified by file management statements also contained in the input file. File management statements are described in the “File Management Statements” in the NX Nastran Quick Reference Guide . 1.2 The NX Nastran DMAP Language The basic components, or objects, of the DMAP language are: Parameters Data Blocks Instructions Scalar quantities used to control the flow of DMAP execution and to communicate options and/or values to modules or functions. Tables or matrices represented by a symbolic name. Statements or modules that process parameters and/or data blocks as input and/or output. The basic syntax of the DMAP language is: • The DMAP language uses free-field input format and is case insensitive. 1-2 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction • A physical entry consists of information in columns 1 through 72. Columns 73 through 80 can be used for comments, but these columns do not appear in the printed listing and are not stored on the database. For the specification of modules or statements, a parent entry continues to a subsequent entry if it terminates in a comma [ , ] or a slash [ / ], or if it is missing a right parenthesis [ ) ]. The dollar sign [ $ ] ends any DMAP instruction and causes all subsequent data to be treated as commentary. UGS recommends following the convention of terminating all DMAP instructions with a dollar sign. DMAP symbolic names are used to identify variable parameters, data blocks, DBVIEW view-names, subDMAPs, or LABEL statements. A symbolic name is composed of alphanumeric characters and is 1 to 8 characters in length. The following characters are allowed: A through Z, and 0 through 9. The first character must be a character from A through Z. • • • 1.3 Parameters Parameters can be either constants, variables, or expressions and can represent one of several types: Type Integer Real Complex Logical Character Description Whole number Decimal number that is a whole number and a decimal point, with an optional decimal fraction. A pair of real numbers representing the real and imaginary parts of a complex quantity Represents either TRUE or FALSE A string of 1 to 80 characters Example(s) 10 or -4 27000. or 2.7E5 or 2.7D5 (1.1,2.3) or (1.D0,3.5D1) TRUE or FALSE ’GEORGE’ Also, the real and complex types are either single or double precision. The following table indicates the storage units required as a function of data type. One storage unit is the basic word size on a computer. Typically, a word is 32 bits long on a short-word computer and 64 bits on a long-word computer. Type Integer Real single precision Real double precision Complex single precision Complex double precision Number of words 1 1 2 2 4 NX Nastran DMAP Programmer’s Guide 1-3 Chapter 1 Direct Matrix Abstraction Type Logical Character Number of words 1 1 to 20 The type of a parameter must be declared in at least one of three ways: Constant Explicit Implicit Inherent in its specification or construction On a TYPE statement for variable parameters In a module’s parameter list for variable parameters Constant Parameters A constant represents a fixed value and is a number (integer, real, or complex), logical, or character string. Integer Constants An integer constant is a whole number with no decimal point. Its form is: snn where: s nn = = a sign, plus (+) or minus (-) a string of digits (0 through 9) s is optional if the sign is positive (+). A minus sign must be used to indicate a negative integer constant. The absolute value of an integer constant cannot be greater than 231 − 1 = 214748367. Real Constants A real constant is a whole number with a decimal point that can be followed by a decimal fraction and/or a decimal exponent. The complete form is: snn.ddEsee snn.ddDsee where: s nn, dd, ee = = A sign, plus (+) or minus (-) Strings of digits (0 through 9) For single precision For double precision 1-4 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction E or D = That snn.dd is multiplied by ee raised to the power of 10. E indicates single precision, and D indicates double precision. s is optional if the sign is positive (+). A minus sign (-) indicates a negative real constant or negative exponent. D is required to specify double precision. E is optional if no exponent is required and the constant is single precision. However, if either E or D is specified, an integer must follow, even if the exponent is 0. Only the leftmost 14 digits in nn.dd are used by NX Nastran. Leading zeros are ignored in counting the leftmost 14 digits. Complex Constants A complex constant is a pair of real constants separated by a comma and enclosed in parentheses. The first real constant represents the real part of the complex number, and the second real constant represents the imaginary part. Logical Constants A logical constant is specified as TRUE or FALSE. Character Constants A character constant is a string of 1 through 80 characters that can have embedded blanks. A character constant must also be enclosed by right hand single quotation marks. Variable Parameters A variable parameter is represented by a symbolic name, and its value can change during the DMAP execution. The name of a variable parameter does not have to be unique with respect to symbolic names for modules, data blocks, subDMAPs, or LABELs. The name of a variable parameter cannot be NOT, AND, XOR, OR, or EQV. Variable parameters can have their attributes (type, authorization, and default) set explicitly with a TYPE DMAP statement or implicitly by a module. (Variable parameters that are saved on the database must also be designated as NDDL parameters in the TYPE DMAP statement.) Variable parameters that are not specified with a TYPE DMAP statement use the attributes from the DMAP instruction where the parameter first appears. Value of a Variable Parameter During a DMAP execution or when restarting a DMAP from the database, the value of a variable parameter is determined by the first applicable value on the following sequential list: 1. Value from the most recently executed assignment DMAP statement or the most recently executed save function (S,N prefix. See “DMAP Modules and Statements”). 2. Value from the PARAM Bulk Data entry, if the parameter NAME has the Y authorization. 3. Value saved on the database, if the parameter NAME is listed with an NDDL TYPE DMAP statement and the run is a restart. NX Nastran DMAP Programmer’s Guide 1-5 Chapter 1 Direct Matrix Abstraction 4. Value from the NAME=v, if present in a non-NDDL parameter TYPE instruction. This value is determined at DMAP compile time from the TYPE instruction (regardless of its location in DMAP) that contains the statement. 5. Default value from the NDDL, if the NDDL keyword is specified on the TYPE DMAP statement. Parameters listed in the NDDL always have a default value of zero, blank, or FALSE, unless a value is explicitly given in the PARAM NDDL statement. 6. Default value from the first occurrence of either a non-NDDL TYPE DMAP statement or a module with a MPL default value. Non-NDDL TYPE DMAP statements have a default value of zero, blank, or FALSE for real or integer, character, or logical parameters. 7. Default value is zero, blank, or FALSE for real or integer, character, or logical parameters. Determining the current value of a variable parameter is summarized in the following table. NDDL TYPEd Not TYPEd Last executed assignment statement or module save (S,N,). The qualifier values for NDDL parameters cannot change. Bulk Data PARAM entry override, if the parameter is type Y and has not been previously reassigned in an assignment (=) statement (unless the PVT module has been executed to reset the Bulk Data and Case Control PARAM entries). Value on the data base NDDL default value Predefined Variable Parameters The program predefines the value of some variable parameters. It is not necessary to type these parameters with a TYPE DMAP statement, nor is it possible to change their type. UGS does not recommend changing these parameter values. The predefined variable parameters are: NAME ALWAYS NEVER TRUE FALSE NOGO VALUE -1 +1 TRUE FALSE 0 TYPE Integer Integer Logical Logical Integer name=vfrom its first occurrence in a TYPE statement TYPE statement default MPL default of parameter first occurrence Initial values for variable parameters can be specified using the PARAM Bulk Data entry or the PARAM Case Control command. Parameter values from the Bulk Data Section are brought into the DMAP sequence via the IFP module. Parameter values from case control are brought into the DMAP sequence via the PVT 1-6 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction module. The PVT module reads the case control PARAM commands and resolves parameter values specified in both the Case Control and Bulk Data Sections. Recommended Parameter Type Specification Follow these recommendations to produce a more readable DMAP sequence where all Y parameters and parameters with non-MPL defaults are specified on TYPE statements. • If the parameter’s value is to be specified in the Case Control or Bulk Data Section, type the parameter near the top of the DMAP sequence, as shown below. TYPE PARM,,type,Y,param_name $ • If the parameter’s default value is defined on the NDDL PARAM statement and you want to use the NDDL default value, type the parameter near the top of the DMAP sequence, as shown below. TYPE PARM,NDDL,type,Y,param_name $ • If the desired default value differs from the MPL default, specify the parameter and the default value on a TYPE statement, as shown below. TYPE PARM,,type,Y,param_name=default_value $ • • Specify in module instructions, as needed, "/param_name/" or "/S,N,param_name/”. Do not use the following obsolete parameter prefix specifications in module instructions: /V,Y,param_name/ /S,Y,param_name/ /V,N,param_name/ /C,Y,param_name/ /C,N,param_name/ For example, UGS recommends the following sequence for setting the TYPE of ALPHA: TYPE PARM,,CS,Y,ALPHA=(1.,1.) $ TYPE PARM,,CS,N,ALPHAX $ . . . ALPHAX=ALPHA $ IF( FLAG ) ALPHAX=CMPLX(BETA,GAMMA) $ . . . ADD A,B/C/ALPHAX $ UGS does not recommend the following: IF( FLAG ) PARAMR . . . ADD A,B/C/V,Y,ALPHA=(1.,1.) $ //’COMPLEX’//BETA/GAMMA/S,Y,ALPHA $ NX Nastran DMAP Programmer’s Guide 1-7 Chapter 1 Direct Matrix Abstraction Expressions and Operators An expression represents a single value and consists of one or more constant and/or variable parameters separated by operators. Expressions are classified as arithmetic, relational, logical, or character. Arithmetic expressions produce numerical values; relational and logical expressions produce logical values. An expression can contain intrinsic functions.

Parentheses are used to change the order of precedence. Operations within parentheses are performed first, with the usual order of precedence being maintained within the parentheses. Operator –,+ Operation Negative or Positive immediately preceded by exponentiation Exponentiation Negative or Positive Multiplication or Division Addition or Subtraction Sample expressions X–Y Interpreted as X(–Y) ** –,+ *, / +,– –X**Y –X – Y X*Y+Z X+Y –(X**Y) (–X) – Y (X*Y)+Z X+Y In general, mixed mode expressions are not supported. For example, to compute A = B*C, where A and B are complex, but C is real, it is necessary to convert C to a complex number: A = B*CMPLX (C), where CMPLX is described under “Intrinsic Functions” in this section. Character Operator The only character operation is concatenation. Its form is shown below. Operator & Operation Concatenation Sample expressions ‘ABC’ & ‘DE’ = ‘ABCDE’ 1-8 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction Relational Operators Relational operators are used to compare two expressions. The result of the comparison is a logical TRUE or FALSE. When arithmetic and relational operators are combined in one expression, the arithmetic operations are performed first. The table below shows the allowable relational operators. Operator = <>,>< < > ≤ ≥ Logical Operators Logical operators perform tests on multiple relations or Boolean operations. A logical operator returns a result that is either TRUE or FALSE. The outcome of a logical operation is determined as shown in the table below. These outcomes are listed in order of precedence. Parentheses are used to change the order of precedence. Operations within parentheses are performed first, with the usual order of precedence being maintained within the parentheses.

All data blocks are comprised of records. Each record can contain a variable number of words. The first record ("Record 0") is called the header record, of which the first two words (when concatenated) form the name of the data block. The third and subsequent words are not usually used. The subsequent records are sometimes called "data records." For tables, the data record can contain a mixture of any type of data; for example, real, integer, complex, character, and so on. For matrices, the data record corresponds to the nonzero values in the column of the matrix; for example, record 3 corresponds to the nonzero values in column 3. The last record is called the trailer record and contains summary information about the table or matrix. Table trailers In tables, the trailer record contains six words. The contents vary among the tables and are described in “Data Blocks” at the end of the table’s description. Table trailers are printed when DIAG 15 is specified in the Executive Control or DIAGON(15) is specified in the DMAP sequence. Matrix trailers In matrices, the characteristics of a matrix are described in a twelve-word matrix trailer. Matrix trailers are printed when DIAG 8 is present in the Executive Control Section DIAGON(8) or is specified in the DMAP sequence. The contents of a matrix trailer are as follows: Word 1 2 Contents Number of columns in matrix Number of rows in matrix 1-10 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction Word 3 4 5 6 7 8 9 10 11 12 Contents Form of the matrix Type of matrix Largest number of nonzero words among all columns Density of the matrix multiplied by 10000 Size in blocks Maximum string length over all strings Number of strings Average bandwidth Maximum bandwidth Number of null columns Form is defined as one of the following: Form 1 2 3 4 5 6 8 9 10 11 13 15 Meaning Square Rectangular Diagonal Lower triangular factor Upper triangular factor Symmetric Identity Pseudo identity Cholesky factor Trapezoidal factor Sparse lower triangular factor Sparse upper triangular factor Type is defined as one of the following: NX Nastran DMAP Programmer’s Guide 1-11 Chapter 1 Direct Matrix Abstraction Type 1 2 3 4 Meaning Real, single precision Real, double precision Complex, single precision Complex, double precision Data Block Type and Status The data block type depends on whether the data block is stored on a permanent or scratch DBset and whether its name appears on a TYPE DB statement. A DBset is a physical file that is a subdivision of the database (see the NX Nastran User’s Guide). There are three types of DMAP data blocks: Permanent NDDL Scratch NDDL Local Referenced on a TYPE DB statement and assigned to a permanent DBset through the NDDL Referenced on a TYPE DB statement and assigned to the SCRATCH DBset through the NDDL Not referenced on a TYPE DB statement and automatically assigned to the SCRATCH DBset. At any point during a DMAP execution a data block is in one of the three following states: Generated Not generated Empty The data block has been created The data block has been deleted or is not yet created The data block has been created but has no data (or purged). In other words, the name of the data block is stored on a permanent DBset without any associated data. Permanent blocks can have all states: generated, not generated, and empty. Empty data blocks are created when a module is executed, but no data is actually generated for the data block. For example, the ADD module has two inputs; if both inputs do not exist (not generated), the output is empty or purged. Empty data blocks are required to support automatic restarts. A permanent data block can be explicitly purged with the PURGEX statement. Permanent data blocks can be deleted from the database with the DELETE statement. Scratch data blocks can have only two states: generated and not generated. These data blocks can be deleted with the DELETE or PURGEX statements. 1.5 Instructions A DMAP instruction can be classified as either a module or a statement. A module is similar to a "macro" function and, in general, processes data blocks as input and/or output. A module can 1-12 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction also have parameters as input and/or output. A statement is any instruction that is not a module and that does not operate on data blocks. Modules A module instruction has the following form: the name of the module followed by a comma [,] and a list of input data block names separated by commas, a slash [/], a list of output data block names separated by commas, a slash, and a list of parameter (variable names or constants) separated by slashes: module_name , input_data_block_list / output_data_block_list / parameter_list $ The dollar sign [$] is required to terminate the module instruction. The modules are described in “Descriptions of DMAP Modules and Statements”. Most modules have a prescribed number of inputs, outputs, and parameters, which are defined in the Module Property List (MPL). The MPL is an internal NX Nastran table that prescribes the exact format of all modules; the number of input and output data block lists and the number, type, and default of the parameters in the parameter list. The MPL can be listed by specifying DIAG 31 in the Executive Control Section. The position of the data block and parameter names is critical to the proper execution of the module. Below is an example using the MPYAD module, which performs the following matrix operation: [D] = SIGNAB*[A][B] + SIGNC*[C] or [D] = SIGNAB*[A] T [B] + SIGNC*[C] where [A], [B], [C] and [D] represent matrices, and SIGNAB and SIGNC represent the sign to be applied to the product and additive matrices, respectively. The format of the MPYAD module is: MPYAD , A , B , C / D / T / SIGNAB / SIGNC / PREC / FORM $ where A, B, and C, represent the input data block names, D represents the output data block name, and T, SIGNAB, SIGNC, PREC, and FORM represent the parameter names. The MPL listing for the MPYAD and PARAML modules appears below: Listing 1-1. Module Properties List. NX Nastran DMAP Programmer’s Guide 1-13 Chapter 1 Direct Matrix Abstraction The MPL listing contains useful information under the following column headers: Header Description MOD-NAME IN OUT ID TYP Module name Number of input data blocks Number of output data blocks Parameter position type of parameter: INT - integer RSP - real single precision RDP - real double precision CSP - complex single precision CDP - complex double precision BCD - character LOG - logical DEFAULT Default value of parameter The other column headers are less important to the DMAP programmer. Some or all data blocks and parameters can be left unspecified (or purged), according to the module description in “Descriptions of DMAP Modules and Statements”. If a parameter is unspecified, the default value is assumed and obtained from the MPL. For example, MPYAD A , B , / D $ According to the MPYAD module description, if C is unspecified, only the matrix multiplication of A and B is performed. Also, by default, T=0 and therefore A is not transposed. SIGNAB and SIGNC parameters are defaulted to 1 resulting in: [D] = [A][B] However, if no default is defined in the MPL, a constant or variable parameter must be specified for the first parameter. For example, -- NO DEFAULT -- on the PARAML module indicates that there is no default value for the first parameter. The first comma after the module name can be omitted as long as the first input data block name is specified. For example, the ELTPRT module has the following format: ELTPRT ECT,GPECT,BGPDT,UNUSED4,EST,CSTM,MPT,DIT,CASECC/ VELEM/PROUT/S,N,ERROR $ 1-14 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction To obtain a printout of the elements connected to each grid point, only GPECT and BGPDTS need to be specified. However, a comma must also be specified after the module name: ELTPRT , ,GPECT,BGPDTS,,,,,,/ $ In addition, trailing commas can be left unspecified: ELTPRT , ,GPECT,BGPDTS,,,,,,/ $ Parameters can be specified on a module as: • • • Input only Input and output Output only Each module has its own rules for parameter specification, as described in “Descriptions of DMAP Modules and Statements”. If a parameter is specified as input, either a constant or variable can be specified. Note that character strings or variables specified for parameters are limited to eight characters in length. For example, the first parameter of the ADD module specifies a scalar multiplier of 1+2i on the first input matrix: ADD A , B / C / (1.,2.) $ or ALPHA: ADD A , B / C / ALPHA $ If a parameter is to be used as both input and output, or output only, a variable name must be specified and preceded by S, N. For example, on the PARAML module, the fourth parameter, TERM, is an output parameter: PARAML A // ’DMI’ / 4 / 7 / S, N, TERM $ TERM is the value of matrix A at column 4 and row 7, which is returned by the PARAM module for later use in the DMAP program. If the S,N prefix is omitted, TERM is assumed to be input only, no fatal message is issued, and the TERM value is incorrect. Statements A statement is any instruction that is not a module and that typically does not produce output data blocks from input data blocks or parameters. Another distinction is that a statement has no definition in the MPL (Module Property List). The different types of statements are: • • • • • Assignment (=) Function Control Declarative Database Function Assignment Statement The assignment statement evaluates an expression and assigns the resulting value to a variable parameter. This statement has the following form: NX Nastran DMAP Programmer’s Guide 1-15 Chapter 1 Direct Matrix Abstraction v = e $ where v is a variable parameter name, and e is an expression. The dollar sign [$] is required to terminate the statement. Assignment statements are arithmetic, logical, or character, depending on the type of the variable parameter. The type of the variable and the expression must be the same. In other words, no mixed mode specification is allowed. Type conversions can be performed with the INT, REAL, CMPLX, ITOL, and LTOI DMAP functions. For character assignment statements, if the length of the expression does not match the size of the variable, the expression is adjusted as follows: • • If the expression is shorter than the variable, the expression is padded with enough blanks on the right before the assignment takes place to make the sizes equal. If the expression is longer than the variable, characters on the right are truncated to make the sizes the same. Function Statement Functions can appear only within an arithmetic or logical expression; they cannot be referenced within module or CALL statements. Execution of the function causes the evaluation of the function and returns a value to the referencing expression. Some functions, however, can appear as a DMAP statement without appearing in an arithmetic or logical expression. These functions are DIAGON, DIAGOFF, NOOP, PUTSYS, PUTDIAG, RDIAGOFF, and RDIAGON. The type of the value returned from a function is dependent on the type of the argument(s) supplied, in addition to the functional operation. In general, the precision (single, double) and form (integer, real, complex) of the result returned by the function carries at least as much information as the arguments supplied. For example, ACOS(X) is typed as follows: X I RS RD CS CD ACOS(X) RS RS RD CS CD Returned values for character functions can be processor dependent.

For complex arguments only one value can be specified. The result is the value and type of the argument. Integer, real single, and real double values are allowed with two arguments only.

For example, to turn on DIAG 8 temporarily and restore the original DIAG 8 setting, the following sequence can be used: TYPE PARM,,I,,DIAG32 $ DIAG32=GETDIAG(1) $ DIAGON(8) $ DIAG 8 WILL BE ON HERE REGARDLESS OF SETTING IN $ EXEC.

See “nastran Command and NASTRAN Statement” in the NX Nastran Quick Reference Guide for a description of various system cells. System cells 253 through 262 are reserved for the DMAP writer. This permits the DMAP writer to pass parameter values in via the NASTRAN statement or between subDMAPs. For example, NASTRAN SYSTEM(253)=4 SOL MYDMAP COMPILE MYDMAP SUBDMAP MYDMAP $ TYPE PARM,,I,N,NP $ . . . IF ( GETSYS(NP,253)<>4 ) THEN $ . . . ENDIF $ NX Nastran DMAP Programmer’s Guide 1-25 Chapter 1 Direct Matrix Abstraction Control Statement The NX Nastran DMAP language contains control statements that perform conditional branching and looping similar to those found in the FORTRAN programming language. The control statements are: Conditional Execution Unconditional Branching Conditional Branching Looping Calling SubDMAP Operations Termination IF JUMP and LABEL IF()THEN, ELSE IF()THEN, ELSE, and ENDIF DO WHILE and ENDDO SUBDMAP, CALL, and RETURN EXIT and END Conditional Execution—IF Statement The IF statement conditionally executes a single DMAP instruction: IF ( logical expression ) instruction $ In other words, if the logical expression is true, the instruction is executed. Instruction is any DMAP module or statement, except a control statement or the FILE, DBVIEW, TYPE and SUBDMAP statements. Examples include: IF ( NOGOA=-1 ) ADD GOAT,GOAQ/GOA $ IF ( ERRFLAG<0 ) CALL ERROR //S,GO/ERROR $ IF ( A AND B ) X=2*Y $ Unconditional Branching—JUMP and LABEL Statements The JUMP and LABEL statements are analogous to the GO TO and CONTINUE statements in FORTRAN, except the LABEL statement cannot appear above the JUMP statement. For example, JUMP n $ . . . LABEL n $ where n is character string, up to eight alphanumeric characters in length, and the first character must be alphabetic. JUMP and LABEL can be used to jump out of a DO WHILE loop or IF()THEN block, but JUMP and LABEL cannot be used to jump into a DO WHILE loop or IF()THEN block. JUMP can appear on an IF statement; however, in this case, UGS recommends using an IF()THEN statement. Conditional Branching—IF ( ) THEN Statement The IF ( ) THEN operation has the following form: 1-26 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction 1. IF(expression)THEN $ . . DMAP executed if expression is TRUE . ENDIF $ 2. IF(expression)THEN $ . . . ELSE $ . . . ENDIF $ DMAP executed if expression is FALSE DMAP executed if expression is TRUE 3. IF(expression 1)THEN $ . . . ELSE IF(expression 2)THEN $ . . . DMAP executed if expression 1 is FALSE and expression 2 is TRUE DMAP executed if expression 1 is TRUE ELSE IF(expression n)THEN $ . . . DMAP executed if expression 1 through expression n-1 are FALSE and expression n is TRUE ELSE $ . . . DMAP executed if expression 1 through expression n are FALSE ENDIF $ The expressions in the above examples are relational and/or logical operations that result in a logical output of either TRUE or FALSE. The allowable relational operators are discussed in “Expressions and Operators” Looping—DO WHILE ( ) Statement DO WHILE(expression) $ . . . NX Nastran DMAP Programmer’s Guide 1-27 Chapter 1 Direct Matrix Abstraction ENDDO $ The expression in the above example is a relational and/or logical operation that results in a logical output of either TRUE or FALSE. The allowable relational and logical operators are discussed in “Expressions and Operators”. There is no limit to the allowable number of DO WHILE statements. Scratch NDDL and local blocks which are first referenced and created inside a DO WHILE loop are automatically deleted at the end of the loop. The FILE statement with the APPEND or SAVE keyword can be specified to override the automatic deletion in order to "save" a scratch data block for subsequent passes through the DO WHILE loop. See the APPEND and FILE statement descriptions in “DMAP Modules and Statements” for examples. Calling SubDMAP Operations—SUBDMAP, CALL, and RETURN Statements The CALL and SUBDMAP statements allow for the definition of DMAP subprograms called subDMAPs. The RETURN statement can be used in a subDMAP to return to the calling subDMAP. The SUBDMAP statement denotes the beginning of a DMAP subprogram; either a main subDMAP or a called subDMAP. A main subDMAP can be invoked with the SOL Executive Control statement and cannot have any arguments. A called subDMAP can or cannot have arguments and is invoked by a CALL statement in another subDMAP, defined as the calling subDMAP. The form of the SUBDMAP and CALL statements are: SUBDMAP subDMAP-name [I1,I2,I3,.../ O1,O2,O3,.../ P1/P2/P3/... $] [I1,I2,I3,.../ O1,O2,O3,.../ [S,]P1/[S,]P2/[S,]P3/...] $ CALL subDMAP-name where subDMAP-name is the name of a subDMAP. The arguments Ii, Oi, and Pi are the list of input data block names, output data block names, and variable parameter names or constant parameters. The specification of arguments is optional. If arguments are specified, the CALL and SUBDMAP statements must agree in order, in number, and, for parameters only, in type. The linker checks for correspondence of the arguments. The linker also checks for consistent parameter authorization if NASTRAN SYSTEM(147)=1. In addition, a view-name defined by the DBVIEW statement cannot be specified in the argument list. If an argument list is specified on the SUBDMAP statement, no argument can be left unspecified. Also, all parameter arguments must be variable parameter names. Any data block argument on the CALL statement can be left unspecified. Inside the called subDMAP, the data block argument is treated as purged. All parameters must be specified on the CALL statement, but the parameters can be either a variable parameter name or a constant value. Also on the CALL statement, parameter values, such as qualifiers or local parameters (which are computed in the called subDMAP), can be returned to calling subDMAP by preceding the parameter name with "S,". This method is called the save option. The save option is not required for parameters specified on TYPE PARM,NDDL statements in the called subDMAP. The RETURN statement can be specified anywhere in the subDMAP. This statement terminates execution of the current subDMAP and resumes execution of the calling subDMAP. If the 1-28 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction RETURN statement is not specified in the subDMAP, all DMAP execution is terminated at the END statement (discussed in the next section). Below is an example using the SUBDMAP, CALL, and RETURN statements. The main subDMAP is called MAIN and contains two calls to subDMAP TEST. In the first CALL to subDMAP TEST, the second input and output data blocks are marked as ",," and are not generated. The value of Q1 is returned as computed in TEST. In both CALL statements, the value of P2 is returned from TEST. Although Q3 can have changed in subDMAP TEST, Q3’s value is not returned to MAIN. In the second call a constant value of 0 is specified for P1. SUBDMAP MAIN $ Main SUBDMAP TYPE PARM,,I,N,Q1=5 $ TYPE PARM,,I,N,P1,P2,P3,Q3 $ . . . CALL TEST A,,C/D,,F/P1/S,P2/S,Q1 $ . . . CALL TEST A,B,C/I,J,K/0/S,P2/Q3 $ . . . END $ SUBDMAP TEST X,Y,Z/L,M,N/A1/A2/A3 $ TYPE PARM,,I,Y,A3 $ TYPE PARM,,I,N,A1,A2 $ . . . RETURN $ END $ The following should also be noted: • The data block names specified on the SUBDMAP statement argument list are called local names and do not appear in any diagnostic output. Diagnostic output, such as data base directory print or DIAG 8, indicates only the top-level name. The top-level name is the name of the data block in the highest CALL statement in which it appears. In the example above, the local names are X, Y, Z, and so on, and the top-level names are A, B, C, and so on. All input data blocks specified on a CALL statement must have been previously defined by output from a module in the calling subDMAP or from a previously specified CALL statement, or specified on TYPE DB statements. See the “TYPE” statement. Recursive subDMAP calls are allowed; for example, a subDMAP can call itself either directly or indirectly. The last parameter in the argument list must not be followed by a slash (/). • • • Termination—EXIT and END statements Both EXIT and END statements terminate the DMAP execution. However, the EXIT statement can be specified at any time in a subDMAP, and the END statement can be specified only once and must appear at the end of a subDMAP. The following example demonstrates the use of both statements: SUBDMAP AAA $ . . (some DMAP instructions) NX Nastran DMAP Programmer’s Guide 1-29 Chapter 1 Direct Matrix Abstraction . IF(ERROR)EXIT$ . . (some DMAP instructions) . END $ If ERROR is true, the EXIT statement is used to terminate the subDMAP. The END statement is required and must be the last statement in the subDMAP. Declarative Statement The declarative statements are TYPE, DBVIEW, and FILE. See “DMAP Modules and Statements” for a description, and “Output from a Previous Module Rule” and “Automatic Deletion of Scratch Data Blocks” for related discussion. Data Base Function Statement The data base function statements are DBEQUIV and DBDELETE. See “DMAP Modules and Statements” for a description. 1.6 Output from a Previous Module Rule If a data block has already been specified as output by a previous module and is specified as output from another module, User Fatal Message 1126 is issued during execution. This principle is called the “output from a previous module” or “output twice” rule. This rule is waived if any of the following is true: • • • The data block is specified on a FILE statement with the APPEND or OVRWRT keyword. The data block is TYPE’d (specified on a TYPE DB statement), and its current qualifier values are different from the qualifier values given at the time of the previous module execution. The data block is specified as output on a CALL statement and TYPE’d. 1.7 Automatic Deletion of Scratch Data Blocks Scratch NDDL and local data blocks are stored on the SCRATCH DBset. A DBset is a physical file that is a subdivision of the database. To minimize the size of the SCRATCH DBset, module scratch files are automatically deleted upon completion of the module and DMAP scratch data blocks are automatically deleted after the DMAP instruction in which they are used last. The location of this DMAP instruction is called the last-time-used (LTU). An LTU is assigned to every data block. When the LTU of an Scratch NDDL data block is reached, the data block is deleted if the current qualifier values match. If the data block’s LTU is skipped, the entire family is deleted, regardless of the current qualifier values. Special rules apply for data blocks specified in the following situations: • For a scratch data block specified before a loop and last used inside the loop, the LTU is extended to the bottom of the loop (for example, ENDDO), meaning that the data block is deleted when the loop is exited. If the data block is Scratch NDDL, the entire family is deleted, regardless of the current qualifier values. 1-30 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction • For a local data block created inside a DMAP loop and last used after the loop, the data block is deleted after the next execution of the top of the loop, for example, DO WHILE, even though the data block’s LTU is located after the loop (for example, when the loop is exited). Thus, the last generated data block can be used after the loop exits. For a scratch data block created and last used inside a DMAP loop, the FILE statement with the SAVE keyword extends the data block’s original LTU to the bottom of the loop. Otherwise, the data block is deleted at the original LTU within the loop. For a Scratch NDDL data block used in a DBVIEW statement, the data block is deleted at the LTU of the view name or the data block name, whichever is last. • • DlAG 57 prints the LTU information of all data blocks and a message indicating when they are deleted. 1.8 Preface Modules and SOLution 100 The preface modules IFP1, XSORT, IFPi, DTIIN, and DMIIN generate data blocks related to the Case Control, Bulk Data, and DMI or DTI entries. These modules are specified at the beginning of all solution sequences. SOLution 100 is also provided for the DMAP writer who wishes to execute his/her DMAP sequences without having to specify the Preface modules IFP1, XSORT, and IFPi. The DMAP writer needs to insert the following DMAP statements in the Executive Control of the input data: 1. SOL 100 COMPILE USERDMAP ALTER 2 2. If matrices or tables are to be input with DMI or DTI Bulk Data entries, the DMIIN or DTIIN modules must be specified by the DMAP writer. For example, the following DMAP statements generate matrices A, B, C, D, and E and tables TA, TB, TC, TD, and TE: DMIIN DMIIN DMI,DMINDX/A,B,C,D,E,,,,,/ $ DMI,DTINDX/TA,TB,TC,TD,TE,,,,,/ $ Data block names A, B, C, D, E, TA, TB, TC, TD, and TE can now be referenced in subsequent DMAP statements. 3. 4. The DMAP writer’s DMAP sequence can now be inserted. TYPE statements that reference data blocks or parameters defined in the NDDL of the structured solution sequences (SOLutions 101 through 200) can also be inserted. 1.9 Processing User Errors Modules used in Phase I of the superelement SOLution sequences (SOLs 101 through 200) include an option to continue processing after fatal errors are discovered and printed in the output file. The module completes processing as best it can, then sets a special integer parameter named NOGO to -1. The output files can be purged or incomplete. If no errors are discovered, NOGO is set to 0. The DMAP writer can choose to branch to the end of a loop or take other NX Nastran DMAP Programmer’s Guide 1-31 Chapter 1 Direct Matrix Abstraction actions when error conditions are discovered. This option is selected by setting SYSTEM cell 82 to 1. Users who insert alters into Phase l should be aware of this option. An example of this option, based on the method used in SOLs 101 through 200, is: PUTSYS(1,82) $ALLOWS DMAP TO FIELD NOGO FLAGS . . . GP2 GEOM2S,EQEXINS,,GEOM2A,EPTA/ECTS,ECTAS $ IF ( NOGO = -1 ) THEN $ CALL ERRPH1 //SUBDMAP/0/-1/DUMMY $ LOOPER RETURN $ CONTINUE TO NEXT SE ALTHOUGH ENDIF $ . . . PUTSYS (0,82) $ DISALLOWS DMAP TO FIELD NOGO FLAGS ERROR FOUND IN CURRENT SE The GEOM2S file contains element connectivity data. If the GP2 module detects errors in this data, it sets NOGO to -1. Modules that presently have this option include: DCMP DECOMP DYCNTRL EMG GP2 GP3 GP4 LCGEN MGEN MTRXIN SEDR SELA SEMA SSG1 TA1 1.10 SubDMAPs DBMGR, DBSTORE, and DBFETCH The DBMGR, DBSTORE, and DBFETCH module capabilities prior to MSC.Nastran Version 66 have been replaced by subDMAPs, as described below. CALL CALL CALL DBMGR //OPT/P2/P3/P4/P5/P6/DB1/DB2/DB3/DB4/DB5 $ DBSTORE DB1,DB2,DB3,DB4,DB5//Q1/Q2/DBSET/COND $ DBFETCH /DB1,DB2,DB3,DB4,DB5/Q1/Q2/FLAG/0/S,SUCCESS $ The complete descriptions can be found in “DMAP Modules and Statements” under subDMAPs DBFETCH, DBMGR, and DBSTORE. 1-32 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction Prior to MSC.Nastran Version 66, data blocks can be stored, fetched, and manipulated from the database via the DMAP modules DBSTORE, DBFETCH and DBMGR. In MSC.Nastran Version 66 these modules were removed in favor of a more robust and automatic capability. To help you store data blocks that are not already defined in the NDDL, a set of subDMAPs are available that emulate most of the capabilities in those modules. The subDMAPs and their capabilities are: CALL DBSTORE CALL DBFETCH CALL DBMGR Store data blocks on the database Retrieve data blocks from the database Perform various functions related to data blocks stored using CALL DBSTORE DIAG 47 can be specified in the Executive Control Section to print diagnostics related to these operations. These subDMAPs are stored in the delivery database and do not have to be compiled if they are being used in any NX Nastran solution sequences. For example: SOL 101 DIAG 47 COMPILE SEDRCVR ALTER ’AFTER ELEMENT STRESS’ CALL CEND DBSTORE OES1,,,,//0/SEID/’ ’/0 $ These subDMAPs are also used in a user’s solution sequence. SOL MYDMAP COMPILE MYDMAP SUBDMAP MYDMAP $ . . . CALL DBSTORE A,,,,//0/1/’ . . . END $ CEND ’/0 $ A listing of these subDMAPs and the subDMAPs that they call (DBSTOR and FNAME) can be obtained with the following input file: COMPILE DBFETCH REF LIST COMPILE DBSTORE REF LIST COMPILE DBFTCH REF LIST COMPILE DBSTOR REF LIST COMPILE FNAME REF LIST COMPILE DBMGR REF LIST CEND NX Nastran DMAP Programmer’s Guide 1-33 Chapter 1 Direct Matrix Abstraction 1.11 WHERE and CONVERT Clauses The WHERE clause is used in the selection of items (data blocks and parameters) on the DBDICT, DBLOCATE, DBLOAD, and DBUNLOAD statements. The CONVERT clause modifies qualifier values of items selected by the WHERE clause on the DBLOCATE and DBLOAD statements. The WHERE and CONVERT clauses specify values for PROJECT, VERSION, qualifiers, and DBSET. PROJECT specifies the project-ID that is originally defined on the PROJECT FMS statement at the time the project is created. VERSION specifies the desired version-ID under the project-ID. Qualifiers are used to uniquely identify items on the database with the same name. For example, data block KAA has SEID as one of its qualifiers, which is the superelement ID. An item can have more than one qualifier and the collection of all qualifiers assigned to an item is called a path. All data blocks and parameters with qualifiers are defined in the NDDL Sequence (see “NASTRAN Data Definition Language (NDDL)”). Data blocks and parameters are defined on the DATABLK and PARAM NDDL statements. The DATABLK and PARAM statements specify the name of the data block, parameter, and also its path name. The path names are defined on the PATH NDDL statement, which lists the qualifiers assigned to the path. Qualifiers are defined on the QUAL NDDL statement. DBSET specifies the desired DBset. The DBset of an item is specified after the LOCATION keyword on the DATABLK and PARAM NDDL statement. The format of the WHERE clause is: WHERE (where-expr) where-expr is a logical expression that specifies the desired values of qualifiers, PROJECT, VERSION, and DBSET. If the result of the logical expression is TRUE for an item on the database, the item is selected. For example, WHERE(VERSlON=4 AND SElD < > 2 AND SElD > 0) selects all items under version 4 for all values of SEID greater than 0 except 2. A simple where-expr is a comparison using the following relational operators = , > ‘ < ‘ ≤, ≥, or utortu. For example, SElD > 0 means if SEID is greater than zero, the logical expression is true. Several simple where expressions can be joined into one where expression by the following logical operators: AND, OR, XOR, and EQV. The NOT operator can be used to negate a where expression. For example, NOT(SEID>0) is the same as SEID≥0. Arithmetic operations and DMAP functions can also be specified in the where expression (see “Expressions and Operators”). If a qualifier in a where-expr is not a qualifier in the path of a specified item, the where-expr is set to FALSE. If the where-expr does not contain a specification for all qualifiers in the path of an item, the unspecified qualifiers are wildcarded. (For example, in the statement quali= * , all values are selected.) The default values of qualifiers, PROJECT, VERSION, and DBSET are described under the statement in which the WHERE clause is specified. Examples of the WHERE clause are: 1. Select all items in the database for all superelements except 10 and 30 from Version 1. WHERE (VERSION=1 AND SEID≥0 AND NOT(SEID=10 OR SEID=30)) 2. Select all entries in database on DBSET=DBALL from all projects and versions. WHERE(PROJECT=PROJECT AND VERSlON>0 AND DBSET=’DBALL’) The CONVERT clause modifies project- and version-ID, DBset-name (see “INIT” in the NX Nastran Quick Reference Guide), and qualifier values of items selected by the WHERE clause on the DBLOCATE and DBLOAD statements. The CONVERT clause contains one or more assignment statements separated by semicolons. The format of the CONVERT clause is: CONVERT(PROJECT=project-expr; VERSION=version-expr; , DBSET=DBset-expr;quali=qual-expri[;...]) 1-34 NX Nastran DMAP Programmer’s Guide Direct Matrix Abstraction The PROJECT and VERSION statements modify the project-ID (see “PROJ” in the NX Nastran Quick Reference Guide) and version-ID. The DBSET statement modifies the DBset-name. The value of quali is replaced by qual-expri for selected items that have quali in their path. qual-expri is any valid expression (see “Expressions and Operators” containing constants or any qualifier name defined in the path of the item. If qual-expri contains names of qualifiers not in the path of the selected item, a fatal message is issued. If project-expr and/or version-expr produces a project- or version-ID which does not exist, one is created. Also, all version-lDs less than version-expr that do not exist are created; but they are “empty.” Examples of the CONVERT clause are: • • Set qualifiers SEID, PEID, and SPC to constants 10, 20, 102 respectively. CONVERT(SEID=10;PEID=20;SPC=102) If more than one value of a qualifier is found for an item by the WHERE clause, each value is processed in qual-expri to define the new qualifier value for each of the selected items. In the example below, if the original values of PEID were 1, 2, and 3; the new values for the SElD qualifier are 2, 4, and 6: • • Set all values of qualifier SElD to be twice the value of the PEID qualifier. CONVERT(SElD=2*PElD) NX Nastran DMAP Programmer’s Guide 1-35 Chapter 2 Overview of Data Blocks • • • Introduction Matrix Data Blocks Table Data Blocks NX Nastran DMAP Programmer’s Guide 2-1 Chapter 2 Overview of Data Blocks 2.1 Introduction Data block descriptions are provided for all matrices and tables that are currently processed by the OUTPUT2 and DBC modules in the NX Nastran solution sequences with PARAM,POST. Data block descriptions are arranged alphabetically by the generic name of the data block. A data block description can encompass descriptions of several data blocks from different modules. For example, the OES data block description describes data blocks OES1, OES2, OESNL, OSTR1, and OES1C which are output by the SDR2, SDR3, SDRNL, and SDRCOMP modules. The generic name of a data block also appears in the “Glossaries” . 2.2 Matrix Data Blocks The rows and columns of most matrices correspond to degree-of-freedom sets which are defined in the USET table. Matrices are usually named according to __rc where r and c are the names of the degree-of-freedom sets for the row and column, respectively. For example, the rows and columns of KFS correspond to the f-set and the s-set. The rows and columns corresponding to degree-of-freedom sets are ordered according to an ascending internal point identification number sequence. This is the same as the external (user-assigned) grid point identification number sequence unless resequencing is requested (PARAM,OLDSEQ,>-1). Some matrices are also named with pseudo-degree-of-freedom set names. W – The set omitted after auto-omit (a-set combines x-set and w-set) X – The set retained after auto-omit (complement of w-set) J – Superelement interior degrees-of-freedom; for example, KJJ and PJ H – Modal degrees-of-freedom; for example, PHDH, MHH, PHF and UHF In some matrices the columns correspond to subcases, normal modes, time steps, or forcing frequencies. These matrices are usually related to loads and solutions and named __r__ where r is the name of the degree-of-freedom set. For example, PG is static loads applied to the g-set and PHA is the a-set eigenvector matrix. In frequency and transient response, an "F" or "T" can also be added to the name. For example, UDF and UDT, are the solution matrices at the d-set for frequency and transient response. Analysis type Linear statics Nonlinear statics Normal or complex eigenvalues Frequency response Transient response Columns correspond to ascending Subcase identification number Loop identification number Mode number Subcase ID and Forcing frequency value Time step value In transient response analysis, the columns of the solution matrix U_T correspond to "time step triplets." The first column in the triplet represents displacement, then velocity and acceleration. The triplet is then repeated for each time step. For example, if there are 10 time steps, U_T has 30 columns. If multiple TSTEP command subcases are requested, there is a separate solution 2-2 NX Nastran DMAP Programmer’s Guide Overview of Data Blocks matrix for each subcase. The columns of the dynamic load, MPCForce, and SPCForce matrices; P_T, QM_T, and Q_T, correspond to time step and, using the example above, they each have 10 columns. In frequency response analysis, the columns of the dynamic load, MPCForce, SPCForce and solution matrices; P_F, QM_F, Q_F, and U_F, correspond to forcing frequency. If multiple dynamic load (DLOAD) subcases are requested with NFREQ number of forcing frequencies, the first NFREQ columns represent the first DLOAD subcase and NFREQ frequencies, the second NFREQ columns represent the second subcase, and so on. For example, if an analysis is performed with four forcing frequencies and three DLOADsubcases, the solution matrix has 12 columns in which the first 4 columns correspond all forcing frequencies in the first subcase. If multiple FREQUENCY command subcases are requested, there is a separate solution matrix for each subcase. For a description of matrix trailers see “Data Blocks” . 2.3 Table Data Blocks This section discusses common attributes across tables. IFP Tables The IFP module processes the Bulk Data Section and creates data blocks which contain images of each Bulk Data entry. Modules IFP2 through IFP9, MODEPT, MODGM2, GP0, SEQP, and MODGM4 then create pseudo-images based on the presence of elements used in hydroelastic, axisymmetric, laminated composite, composite beam, acoustic, hyperelastic, beam library and p-version analyses. For example, the IFP6 module converts PCOMP and MAT8 images to MAT2 and PSHELL pseudo-images. All of the tables produced by these modules are also called "IFP Tables." In an IFP Table there is one record written for each image type present in, or derived from, the Bulk Data Section and that record contains all of the images for that type. If the image type is not present, no record is written. IFP Table Header Words and Trailer Bits The first three words in all IFP Tables uniquely identify or label the contents of the record and are called "header words." The second header word indicates a bit position, called a "trailer bit", in the table trailer. The trailer bit indicates the presence of record type in the data block; that is, if the record is present in the table, the bit is turned on in the trailer. There are a total of 176 trailer bits. The first 96 trailer bits correspond to bit positions 1 through 16, numbered from the right, in each trailer word and beginning with trailer word 1. The second 80 trailer bits correspond to bit positions 17 through 32, numbered from the right, in each trailer word and beginning with trailer word 1. The table below shows the correspondence between a trailer bit and its word and bit location in the trailer. Trailer Bit Word 1 – 16 17 – 32 33 – 48 1 2 3 Location in trailer Position 16 – 1 16 – 1 16 – 1 NX Nastran DMAP Programmer’s Guide 2-3 Chapter 2 Overview of Data Blocks Trailer Bit Word 49 – 64 65 – 80 81 – 96 97 – 112 113 – 128 129 – 144 145 – 160 161 – 176 4 5 6 1 2 3 4 5 Location in trailer Position 16 – 1 16 – 1 16 – 1 32 – 17 32 – 17 32 – 17 32 – 17 32 – 17 For example, the GRID record in the GEOM1 data block is assigned to trailer bit 45 which corresponds to the 4th bit position, numbered from the right, in trailer word 3. Based on the trailer bit, the following FORTRAN statements can be used to determine the corresponding trailer word and bit position: WORD = MOD(TBIT-1,96)/16 + 1 BIT = 16*(1+TBIT/97) - MOD(TBIT-1,16) where TBIT = trailer bit from the second word of the header record WORD = trailer word BIT = trailer word bit position numbered from the right and all variables are defined as integers. OFP Tables The header record of all OFP tables contains codes which indicate how the output should be labeled, formatted, and printed.

The integer values 4 and 1 in these examples are function codes. Function codes specify operations to perform on the value in the data block.

The following lists the available function codes and their operation: Function codes 1 2 3 4 5 6 7 Operation if (item_name/1000 = 2,3,4,6) then return 2, else return 1 mod(item_name,100) mod(item_name,1000) item_name/10 mod(item_name,10) if iand(item_name,8)<> then set to 0, else set to 1 if item_name/1000 = 0 or 2, then set to 0 = 1,3 or 4, then set to 1 > 4, then set to 2. >65535 iand(item_name,iand(func_code,65535)) For example, if a value of 100 is found in an ACODE,4 field, the function_code of 4 results in the operation item_name/10 = 100/10 = 10. Thus the data format under the ACODE,4=10 row would be used.

The BITINFO in ENTRY=DWNCNCT indicates the downstream superelement(s?). Bit Number 0 1 through NBRSE-1 Downstream superelement is: The residual structure The superelement(s) corresponding to the INTIDX-th bit(s) 5. In ENTRY=GRIDMAP, bits are numbered left to right beginning with zero and span LENTRY-1 words. Bit number 0 1 through NBRSE-1 NBRSE NBRSE+1 MAXBIT-IDBITS through MAXBIT Meaning Grid is connected to the residual structure Grid is connected to the superelement(s) corresponding to the INTIDX-th bit(s) Grid is a scalar point Grid is an incongruent boundary point Internal superelement index (INTIDX) to which grid is interior 6. where MAXBIT = NBPW*(LENTRY-1)-1, NBPW is the number of bits per word, and "incongruent" indicates inconsistent coordinate systems on the boundary point. 7. In RECORD=INFO the primary superelement exterior grid points are sorted in the order of the secondary exterior grid points. Only if SEQSEP is specified. 8. SELABEL is created by SEP1X only. 9. LENTRY is computed from IDBITS: 10. IDBITS is the minimum number of bits required to represent NBRSE. IDBITS = int ( ln ( max (NBRSE,1)) ln 2 ln 2 11. where ln is the natural logarithm and int is the integer function. 12.

For example, if NBRSE=50 and NBPW=32, IDBITS=6 and LENTRY=3. 14. The structure of RECORD=MAP is the same for SEP1 and SEP1X, but the content is different. For SEP1X, GRIDID in RECORD=MAP identifies only boundary grid points and GRIDBIT delineates to which superelement the point connects. For SEP1 the bits are not really clear in meaning. However some rules tend to indicate when the exterior grid becomes interior. 15. RECORD=INFO is the same between both systems, although modules SEP1X and SEP2X do not use ENTRY=ELIDS. 16. ENTRY=PGRID exists only for secondary superelements with resequencing, that is, bit 1 is on in TYPE, and lists the relative primary grid points in the same order as ENTRY=EXTGRD. 5.27 SET Table of combined sets Record 0 – HEADER Word 1 Name NAME(2) Type CHAR4 Description Data block name Record 1 – (*) Word 1 2 3 4 5 Name ID TYPE SETORIG SETLEN SETMEM Type I I I I I Description Set identification number Set type Origin of set Length of set Set members Word 5 repeats SETLEN times 5-286 NX Nastran DMAP Programmer’s Guide Data Block Descriptions O-V Record 2 – TRAILER Word 1 2 3 Name WORD1 WORD2 UNDEF(4 ) Type I I None Description Number of sets Number of members in largest set Notes: 1.

The NDDL describes the hierarchical data structure of the NX Nastran database. 2. The NDDL provides the mechanism, in conjunction with the TYPE DMAP statement, for determining which NX Nastran generated data blocks or parameters or both are stored on the database. 3. The NDDL provides the schema necessary for representing the data block data structure. 4. The NDDL and its associated query language provide the means for selecting specific data blocks in the form of flat tables from the hierarchical database structure, thus admitting them to relational database manipulation. 5. The NDDL provides the necessary data dependencies for automatic modified restarts. Descriptions of NDDL Statements DATABLK DEPEN PARAM PATH QUAL Define a data block’s name, path, and location and describe its contents Define a data block, parameter, or virtual parameter to be dependent upon other data block(s), parameter(s) or virtual parameter(s) Define a parameter’s name, type, path, location, and default value List the QUALifiers to be used in accessing the data block or parameter via the NDDL Define a qualifier’s name, type and default value 7.2 Detailed Description of NDDL Statements Syntactical Descriptions In the descriptions of the NDDL statements, the following notation is used: 1. Slashes, colons, and parentheses must be specified as shown. 2. Uppercase letters are keywords and must be specified as shown. 3. Lowercase letters represent variables, the permissible values of which are indicated in the descriptive text. 4. Shaded words indicate the default. 5. One or more items in square brackets [ ] are optional. If the describers are stacked vertically, only one can be specified. 6. One or more items in braces { } must be specified. If the describers are stacked vertically, only one can be specified. 7-2 NX Nastran DMAP Programmer’s Guide NASTRAN Data Definition Language (NDDL) DATABLK Describes data blocks used for NDDL access A data block is a collection of matrix columns or table records and can be broken down into the following entities: 1. Record (or column) is a group of items and/or entries. 2. Entry is a group of items and/or entries within a record. 3. Item is a single scalar quantity; such as an integer, real number, complex number, character string, or logical. Format: DATABLK,db_name,PATH=pathname,LOCATION=loc_param, where: style SAMEAS db_description = = = The db_description has special rules. Only TABLE(OFP) and TABLE(CASE) are allowed. The db_description on another DATABLK, sname statement. One or more record descriptions providing a word-by-word description of each record in which each word (or item) is assigned a name and type. where: RECORD(*) = RECORD = rec_description defines all records. It can be specified only once following RECORD=HEADER. rec_name[(h1 [,h2 [,h3 ]]] assigns a name to the record and can optionally indicate that the record begins with one to three integers called header words. This format can be specified more than once. Only a few data blocks have this type of record; such as IFP module output data blocks. rec_description contains one or more of the following rec_components that can be repeated and in any order: • item_component defines a single item. NX Nastran DMAP Programmer’s Guide 7-3 Chapter 7 NASTRAN Data Definition Language (NDDL) • • entry_component defines a description of one or more rec_components that can be repeated in the record. either_component defines a description of one or more rec_components that is conditional upon the value of another item anywhere in the record. item_component has one of the following forms: where: rep_count C = = The number of times the item is repeated. The default is zero. item_name is referenced by BACK in an either_component or COUNT in an entry_component. • item_type is: Item type I RS RD CS CD CHARi LOGICAL Description Integer Real — single precision Real — double precision Complex — single precision Complex — double precision Character (i = length) Logical • UNDEF indicates a dummy item that is one machine-word in length. entry_component has the following form: ENTRY[ = entry-name], rec_component 7-4 NX Nastran DMAP Programmer’s Guide NASTRAN Data Definition Language (NDDL) where: COUNT = The number of times the entry occurs in the record. item_name specifies the name of an item in the record whose value specifies the number of occurrences and n specifies a constant integer value for the number of occurrences. An entry description specified on another ENTRY=sentry_name A numeric value(s) that identifies the end of repeating ENTRY... ENDENTRY grouping. If this is specified, no more rec_components follow in the record and RECORD or EOF must follow. This is required; it terminates the entry_components. SAMEAS end_valuei If EOR ENDENTRY = = = = either_component has the following form: where: AHEAD or BACK = An item defined elsewhere in the record. NX Nastran DMAP Programmer’s Guide 7-5 Chapter 7 NASTRAN Data Definition Language (NDDL) OR ENDEITH = = The beginning of an optional description of the item=item_valn. This is required and terminates the either_component. Keywords: TYPE TABLE TABLE (CASE) TABLE (OFP) MATRIX UNSTRUCTURED EOR EOF Defines the class or characteristics of information it contains. A collection of records. Special style of table for Case Control tables. Special style of table that are suitable for input to the OFP module. A M by N dimensional array of related items obeying the rules of matrix algebra. The data block has no description. db_description, and SAMEAS are ignored. End of record description. End of the data block description. Variables: db_name Data block name; 1 through 8 characters in length. The first character must be alphabetic. The following characters can be used for datablock-names: A through Z and 0 through 9. Name of the path, which is also referenced on a PATH statement. Variable character parameter name with a value that is the DBset name. See the PARAM NDDL statement and the INlT FMS statement. Record name (optional). Entry name (optional). Item name. Item_name can have an integer argument and would then take the form: item_name(i) where i is an explicit integer value. Item value. Function code. (Optional) Specifies an operation to perform on the item_name value found in the data block. The result of the operation will then be compared to item_val. pathname loc_param rec_name entry_name item_name item_vali func_code 7-6 NX Nastran DMAP Programmer’s Guide NASTRAN Data Definition Language (NDDL) Remarks: 1. In general, the data block completely describes all possible records of a data block. At any given instance, some or even all of the records that comprise the description cannot physically exist in any given data block. 2. For UNDEF items, DEPENdencies are not checked. For transfer of data between machine types, they are considered integer zero. Examples: 1. The simplest DATABLK statement might be of the form: DATABLK,INDATA,PATH=DMS,LOCATION=DBDN,EOF A more complex specification of a DATABLK statement is of the form: DATABLK,GEOM4S,TYPE=TABLE,PATH=PEIDI,LOCATION=IFPX,SAMEAS, GEOM4,EOF In the above statement, SAMEAS,GEOM4 specifies that GEOM4S has the same data block description specified under the DATABLK,GEOM4 statement. 2. Consider the following: DATABLK ,EQEXIN,TYPE=TABLE,PATH=PEIDI,LOCATION=IFPX, RECORD=HEADER,NAME(2),CHAR4,EOR, RECORD=EXT2INT, GRIDID,I,INTERNAL,I, EOR, RECORD=EXT2SIL, GRIDID,I,TENXSIL,I,EOR,EOF The NAME(2) above represents a two-word item with each word four characters in length. The RECORD=EXT2INT gives this particular record the record-name EXT2INT. In the record named EXT2INT there are two integer items called GRIDID and INTERNAL. These two groups are repeated until the EOR is encountered. A simple ENTRY ... ENDENTRY grouping is: RECORD=MAT9(2603,26,300), MID,I, ENTRY=GEES, G(21),RS, ENDENTRY, RHO,RS,..., EOR, In the above example, the Gs were grouped into an ENTRY - ENDENTRY group called GEES with 21 entries. The group items can be accessed as a whole group or as individual members. Also note the (2603,26,300) entry. Internally, for many records, NX Nastran sees the describer (2603,26,300), rather than the record name (for example, MAT9). Another example of an ENTRY ... ENDENTRY group is as follows: RECORD=CYJOIN(5210,52,257), SIDE,I,C,I, ENTRY, G1,I, ENDENTRY,WITH,-1, EOR, In this example, the ENTRY ... ENDENTRY group in the CYJOIN record consists of an indefinite number of G1 data-items. When the value -1 (which is physically part of the record) is NX Nastran DMAP Programmer’s Guide 7-7 Chapter 7 NASTRAN Data Definition Language (NDDL) encountered, repetition of the ENTRY ... ENDENTRY group stops. Another similar example is of the form: RECORD=MPC(4901,49,17), SID,I,..., ENTRY, G1,I,C1,I,A1,RS, ENDENTRY,WITH,(-1,-1,-1),EOR, In the above MPC record, the group G1, C1, A1, repeats until -1 -1 -1 is encountered in the record. A complex example of ENTRY ... ENDENTRY groups is shown next. RECORD=RBE3(7101,71,187), EID,I,REFGRID,I,REFC,I, ENTRY, WT1,RS,C1,I, ENTRY, G1,I, ENDENTRY,WITH,-1, ENDENTRY,WITH,-2, ENTRY, GM1,I,CM1,I, ENDENTRY,WITH,-3, EOR, In this example, an ENTRY ... ENDENTRY group is shown nested within another ENTRY ... ENDENTRY group. If an ENTRY .. ENDENTRY group appears in another ENTRY ... ENDENTRY group, it must be entirely contained in the particular group. The outer ENTRY ... ENDENTRY group of this example uses the ElTHER,OR clause to select the ENDENTRY statement. In this particular example, the inner ENTRY ... ENDENTRY group is terminated by -1. The outer ENTRY ... ENDENTRY group is terminated when a -2 is encountered. If a -2 is encountered, another ENTRY ... ENDENTRY group terminating with -3 is executed. If -3 is encountered the outer loop terminates. The record is continuously repeated in this fashion until the EOR is encountered. The next example uses EITHER,OR clauses to select one of several possible table formats including an ENTRY ... ENDENTRY grouping. RECORD=RELEASE(1310,13,247), SEID,I,C,I, EITHER,0, ENTRY, G1,I, ENDENTRY,WITH,-1, OR,1, G1,I,G2,I, OR,-1 ENDEITH, EOR, The RELEASE record represents three possible forms of the Bulk Data entry RELEASE. The ENTRY ... ENDENTRY group represents an open-ended list of grid point identifiers terminated by -1. The first OR represents a “THRU” option while the second OR represents an “ALL” option. Another use of the SAMEAS clause is as follows: ,..., ENTRY=SOLDSP,SAMEAS,NONLIN,ENDENTRY, This statement says that SOLDSP entry has an identical group structure to an ENTRY=NONLIN grouping, which is in the same data block and comes physically before the SOLDSP entry. The COUNT = n is shown in the next example: ,..., 7-8 NX Nastran DMAP Programmer’s Guide NASTRAN Data Definition Language (NDDL) RECORD=PBEAM,(5402,54,262) PID,I,MID,I,N,I,CCF,I,X,I, ENTRY=SECTIONS, S0,I,XXB,RS,A,RS,I1,RS,I2,RS,I12,RS,J,RS,NSM,RS, C1 ,RS,C2,RS,D1,RS,D2,RS,E1,RS,E2,RS,F1,RS,F2,RS, ENDENTRY,COUNT=11, K1,RS, ... , N2B,RS, EOR, ... The STATIONS entry is to be repeated 10 times in addition to the entry explicitly described. Thus there are 11 such entries. The next example shows the use of COUNT = item-id and WITH,EOR ,..., UNUSED(67),I, LSEM(C),I, ENTRY, COEF,RS, ENDENTRY,COUNT=LSEM, ENTRY=SETS, SETID,I, LSET(C),I, ENTRY, SET,I, ENDENTRY,COUNT=LSET, ENDENTRY,WITH,EOR,EOF The number of data items in COEFF is LSEM. The entry SETS represents an ENTRY ... ENDENTRY group, which ends when an EOR is reached. SET contains LSET data items for each repetition through the ENTRY ... ENDENTRY group. The next example shows a use of UNDEF, length. RECORD=CCONE(2315,23,0), EID,I,PID,I, UNDEF,18, EOR, Here UNDEF,18 says that the next 18 items in the table are undefined. Neither item-name nor data-type are defined. The next example shows the use of AHEAD(item-name). RECORD=CBAR(2408,24,180), EID,I,PID,I,GA,I,GB,I, EITHER,AHEAD(F)=1, X1 ,RS,X2,RS,X3,RS,F,I OR,2, GO,I,UNDEF,2,F,I, ENDEITH, ... In this example, AHEAD(F) says read F, which is required to be integer to determine the appropriate description, N. DEPEN Specifies the dependence of a data block or parameter Specifies the dependence of a data block or parameter on another data block, parameter, or virtual parameter. NX Nastran DMAP Programmer’s Guide 7-9 Chapter 7 NASTRAN Data Definition Language (NDDL) Format: Meaning: dep_* is dependent upon indep_*. In other words, if any or all of indep_* changes, or is also marked for deletion, the RESTART module detects changes and marks dep_* for deletion. Variables: dep_* indep_* desc_loc Dependent data block, parameter, or virtual parameter as indicated by DB, P, or VP, respectively. Independent data block, parameter, or virtual parameter as indicated by DB, P, or VP, respectively. Description locator of the independent record, entry, or item. The format is [record_name][:[entry_name]][:[item_name]]. Remarks: 1. des_loc is specified in order to isolate the independent data. In other words, the dependency is limited to a specific record, entry, and/or item. For example, DEPEN A/B $ delete A if any item in B changes DEPEN A/B:C $ delete A only if record C changes DEPEN A/B:C:D $ delete A only if entry D of record C changes DEPEN A/B:C:D:E $ delete A only if item E in entry D of record C changes 2.

In both cases, AELOOP skips to the NSKIP-th subcase in CASECC and copies the subcase to CASEA. CASEA is then interrogated for a TRIM or a DIVERG Case Control command. 1. If it is TRIM, the NSKIP parameter is incremented by one and the MACH and Q values are read from the requested TRIM Bulk Data entry image in EDT. 2. If it is DIVERG, MFLG is checked for any remaining MACH numbers in the subcase. If any are found, MFLG is incremented by one and the MFLG-th MACH number is read from the requested DIVERG Bulk Data entry image in EDT. If the current MACH number is the last MACH number, MFLG is set to 0 and NSKIP is incremented by one.

DBCPATH is a parameter defined on a statement in the NASTRAN NDDL; that is, PARAM,DBCPATH = 0,PATH = DBCQUAL PATH DBCQUAL QUAL1,QUAL2,QUAL3,etc. where QUALi selects the QUALifier values associated with the PATH of the input data blocks from NASTRAN to be written along with the input data blocks on the DBC database. In other words, the intersection of the PATH DBCQUAL and the PATH of the input data blocks forms the set of QUALifiers to be written to the DBC database and associated with the input data blocks. Also, the PROJECT and VERSION is written. UGS recommends that the input data blocks all have the same PATH. If it is not NDDL, only the PROJECT and VERSION are associated with the input data blocks on the DBC database. 3. Generic data blocks: ECT, GEOM1, and EQEXIN, must exist on POSTU (when PROGRAM =’XL’) or GEOMU (when PROGRAM =’GRASP’) prior to the conversion of the following data blocks: OUG, OES, OEF, OPG, OQG, and GPS. 4.

Delete parameters. param-list specifies a list of parameters separated by commas. Logical expression that specifies the desired values of colnames described in Table 2 under the “DBDICT” statement. If the where-expr is true, the named items are deleted. For example, WHERE(VERSION=4 AND SEID<>2 AND SEID>0) selects all items under version 4 for all values of SEID greater than 0 except 2. See “WHERE and CONVERT Clauses” for a further description. The default for VERSION and PROJECT is the current version and project. See also Remark 1. Remarks: 1. The where-expr has the following rules: If the where-expr specifies a colname that is not assigned to the data block or parameter, none of that data block or parameter is deleted. For example, given that SPC is not a qualifier for KGG, the following DBDELETE statement does not delete any KGG: DBDELETE DATABLK=KGG WHERE(SPC=10)$ If the where-expr does not specify a colname that is assigned to the data block (or parameter), the current value of the qualifier is assumed. For example, given that SEID is a qualifier for KAA, the following DBDICT statements are equivalent: SPC=10 $ DBDELETE DATABLK=KAA $ or DBDELETE DATABLK=KAA WHERE(SPC=10) $ The WILDCARD keyword can be added in order to wildcard all qualifiers not already specified in where-expr. For example, to delete all KAA where SPC=10 and regardless of MPC, SEID, and so on.: DBDELETE DATABLK=KAA WHERE(SPC=10 AND WILDCARD) $ Note: WILDCARD applies only to qualifiers and not colnames like PROJECT, PROJECT, VERSION, CDATE, and so on. 2.

The where-expr has the following rules: • If the where-expr specifies a colname that is not assigned to the data block or parameter, no directory information is printed for that data block or parameter. For example, given that SPC is not a qualifier for KGG, the following DBDICT statement produces no output: DBDICT DATABLK=KGG WHERE(SPC=10) $ • If the where-expr does not specify a colname that is assigned to the data block (or parameter), the qualifier is wildcarded. For example, given that SEID is a qualifier for KAA, the following DBDICT statements are equivalent: DBDICT DATABLK=KAA $ DBDICT DATABLK=KAA WHERE(SEID = *) $ Examples: 1. Print the Project Version Table with a title. DBDICT PROJVERS SORT(PROJNO,VERSION), LABEL(’PROJECT VERSION TABLE’ LEFT) $ 2. Print a directory of all data blocks qualified with PEID = 10 or SEID = 10. Print columns for the NAME and DBSET, and the qualifiers SPC, MPC, and LOAD. DBDICT DATABLK SELECT(NAME,SPC,MPC,LOAD,DBSET,SIZE, SEID,PEID) , SORT(NAME,SIZE=D) WHERE( SEID=10 OR PEID=10) $ 9.41 DBEQUIV Equivalences (or copies) NDDL data blocks and parameters Equivalences (or copies) NDDL data blocks and parameters based upon a qualifiers in a CONVERT clause. An optional WHERE and can be specified for a more selective equivalence. Format: 9-76 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Describers: datablk-list Specifies a list of data blocks separated by commas. The default is *, which selects all data blocks. The equivalenced data block can be renamed by specifying a slash after the old name followed by the new name. For example, if KLL is to be renamed to KLL1, DATABLK=(KLL/KLL1) is specified. Specifies a list of parameters separated by commas. The default is *, which selected all parameters. The equivalenced parameter can be renamed by specifying a slash after the old name followed by the new name. For example, if LUSETS is to be renamed to LUSET, PARAM=(LUSETS/LUSET) is specified. Logical expression that specifies the desired values of colnames described in Table 2 under the DBDICT statement. If where-expr is true, the named items are equivalenced. For example, WHERE(VERSION=4 AND SEID<>2 AND SEID>0) selects all items under version 4 for all values of SEID greater than 0 except 2. See WHERE and CONVERT Clauses” for a further description. The default for VERSION and PROJECT is the current version and project. See Remark 1 for more information. Modifies the values for PROJECT, VERSION, DBSET, and qualifiers selected by the where-expr. The format of convert-expr is: PROJECT=project-expr;VERSION=version-expr; DBSET=DBsetname;quali=qual-expri[;...] param-list where-expr convert-expr For example, CONVERT (SEID=100+SEID; SPC=102). See “WHERE and CONVERT Clauses” for a further discussion on WHERE and CONVERT clauses. The default action for VERSION and PROJECT is to convert to the current version-ID and current project-ID. But if either PROJECT or VERSION is specified in the convert-expr, both must be specified. OVRWRT NOOVRWRT By default (that is, NOOVRWRT), duplicate data blocks or parameters on the created by DBEQUIV cause a fatal message. A duplicate means that a data block or parameter has not only the same name but also the same qualifier values, PROJECT, VERSION, and DBSET as the primary data block or parameter. If OVRWRT is specified, the primary data block is overwritten. By default, data blocks and parameters created by DBEQUIV cannot be output again in a subsequent DMAP module. If RESTART is specified, the selected data blocks and parameters can be overwritten once. RESTART Remarks: 1. The where-expr has the following rules: If the where-expr specifies a colname that is not assigned to the data block or parameter, none of that data block or parameter is equivalenced. For example, given that SPC is not a qualifier for KGG, the following DBEQUIV statement does not equivalence any KGG: DBEQUIV DATABLK=KGG WHERE(SPC=10) CONVERT(SPC=20) $ NX Nastran DMAP Programmer’s Guide 9-77 Chapter 9 Descriptions of DMAP Modules and Statements If the where-expr does not specify a colname that is assigned to the data block (or parameter), the current value of the qualifier is assumed. For example, given that SEID is a qualifier for KAA, the following DBEQUIV statements are equivalent: SPC=10 $ DBEQUIV DATABLK=KAA CONVERT(SPC=20) $ or DBEQUIV DATABLK=KAA WHERE(SPC=10) CONVERT(SPC=20) $ The WILDCARD keyword can be added in order to wildcard all qualifiers not already specified in where-expr. For example, to equivalence all KAA where SPC=10 and regardless of MPC, SEID, and so on: DBEQUIV DATABLK=KAA WHERE(SPC=10 AND WILDCARD) CONVERT(SPC=20) $ WILDCARD applies only to qualifiers and not colnames like PROJECT, PROJNO, VERSION, CDATE, and so on. 2. The data block and parameter names in datablk-list and param-list cannot be alias names specified on the subDMAP argument list. datablk-list and param-list must specify the name of the data block or parameter as defined in the NDDL. 9.42 SubDMAP DBFETCH Fetch data blocks stored by DBSTORE Retrieves user-specified data blocks on the database previously stored with CALL DBSTORE.

Remarks: 1. All parameters must be specified even if they are not used or the default value is desired. Unused integer parameters can be set to 0. If DBSET is blank; that is, ’ ’ (a string with 5 blanks), DBi is stored on DBset DBALL. NX Nastran DMAP Programmer’s Guide 9-83 Chapter 9 Descriptions of DMAP Modules and Statements 2. DBi is stored under the database data block named ZUZR11 qualified with ZNAME = DBi, ZUZR1 = Q1, ZUZR2 = Q2, ZUZR3 = 0 on DBset = DBSET. 3. DBSET should not be ’SCRATCH’ or refer to a scratch dbset. 4. If CALL DBSTORE is to be used in restart runs with the structured solution sequences (SOLs 101 through 200), PUTSYS(1, 109) should be specified just before CALL DBSTORE and PUTSYS(0, 109) just after. See Example 1. 5. If DBi appears on the SUBDMAP statement, the actual name of the data block to be stored on the database is the name that appears on the “highest” CALL statement that contains DBi.

The first character must be alphabetic. The following characters can be used for view-names: A through Z and 0 through 9. Name of a data block. A logical expression that specifies the desired values of qualifiers, PROJECT, PROJNO, VERSION, and DBSET. For example, WHERE(VERSION=4 AND SEID< >2 AND SEID>0) selects all items under version 4 for all values of SEID greater than 0 except 2. See “WHERE and CONVERT Clauses” and Remark 6. data-block where-expr Remarks: 1. DBVIEW is a nonexecutable statement defined only at compilation. It is not affected by IF ( ) THEN or DO WHILE blocks. Where-expr, however, is evaluated dynamically for the current values of data-block qualifiers at the module where view-name is specified for input. 2. DBVIEW must be specified prior to the first occurrence of the use of the view-name. It can be specified only as an input data block to a DMAP module. 3. If the data-block is “not generated” or if no data blocks satisfy the where-expr, the view-name is considered as “not generated.” Also, if the where-expr contains a qualifier that is not in the path of the data-block, the view-name is not generated. 4. view-name is recognized only in the current subDMAP. 5. A view-name that results in more than one data block is also called a family. If a family is specified as input to a module that does not use families, the first data block stored is the one that is used. 6. The values assigned to qualifiers not specified in the where-expr are taken from current values. “AND WILDCARD” can be specified in the where-expr to indicate that unspecified qualifiers do not have to match their current values to satisfy the DBVIEW statement. NX Nastran DMAP Programmer’s Guide 9-85 Chapter 9 Descriptions of DMAP Modules and Statements 7. A comma can be used in place of the spaces shown under Format to continue the DBVIEW statement on more than one line. For example, DBVIEW UGX=UG, (WHERE SEID=10 AND, SPC=20, AND VERSION=5) $ Examples: 1. The following DBVIEW statement creates a view-name of KAA data blocks called KAA10 for the path qualifier (see the PATH NDDL-Statement) SEID = 10 and for the current values of the remaining KAA path qualifiers. DBVIEW KAA10 = KAA (WHERE SEID=10) $ 2. The following DBVIEW statement creates a view-name of the data block BULK, which is stored under the version referenced on the RESTART FMS statement and gives it the virtual name BULKR to differentiate it from the current data block BULK.

All Remarks given for the DECOMP module also apply to the DCMP module. 2. If given unsymmetric matrices (“Form 1"), the mechanism diagnostics are not provided. The module is then functionally equivalent to the DECOMP module. 3. Data blocks USET, SIL, and PARTVEC and parameter SETNAME are required for the most efficient method of decomposition. PARTVEC is only required if A is not the same size as SETNAME. 4. If A is symmetric, U contains the "MATRIX/FACTOR DIAGONAL RATIO values printed under UWM 4698. The mathematical definition of U is Diag(A) = Ad, a vector. Diag(T) = Dd, a vector. In some circumstances T is not a diagonal matrix. The high ratio test being defined here has no validity in the regions where there are off-diagonal terms (2 by 2 pivots), so those rows are ignored in this testing. The ratio is defined as Vi = Adi/Ddi Regions where the model is approaching singularity have small Ddi terms. They are divided into Adi to non-dimensionalize them, and checked against a quality parameter value named MAXRATIO. The default value for MAXRATIO is 1.E7, but you can change its value. Terms less than MAXRATIO are set to zero in Vi. If any terms remain, the matrix is identified as singular, and various warning and fatal messages can appear, depending on the context in which the DCMP module is being called. 9-88 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements This vector can be used to better identify singularities and provide other actions when they are being approached. This feature is used in normal modes analysis, where points with high ratios are automatically constrained to ground, to make the eigensolution more stable.

Nonstandard triangular factor matrix data blocks are used to improve the efficiency of the back substitution process in module FBS. 3. if the value of 16 is specified for the DECOMP parameter, SING is set to one if unit values are placed on the diagonal. 4. if KSYM = 3, the [A] matrix is decomposed through the first n degrees of freedom, where n is the value provided by the CHOLSKY parameter. The resulting trapezoidal factor is output as [L] and the remaining undecomposed partition of the [A] matrix, with contributions from the first n degrees of freedom added, is output as [U ]. 5. Cholesky factors (matrix form 10) can be used for all standard matrix operations; for example, ADD, MPYAD, and so on. All other factors are packed, nonstandard data blocks as described in Remark 2 and cannot be processed by other matrix modules except where noted. 6. The output triangular and trapezoidal matrices has the following forms in the matrix trailer: Form 4 5 10 11 13 15 Factor type Lower triangle Upper triangle Cholesky Trapezoidal Lower triangular Lower or upper triangular Matrix type Symmetric or unsymmetric Unsymmetric only Symmetric only Symmetric only Sparse symmetric Sparse unsymmetric 7. In decomposing symmetric matrices, [A] = [L] [D] [L]T, the diagonal factor [D] is stored in the diagonal of the [LD] matrix output. The [U ] = [L]T factor is not output for this case. 8. Matrices with zero diagonal terms can be reliably solved if the corresponding leading minor is nonzero. A more conservative course is to take a fatal error exit when zero diagonals occur, regardless of the value of the leading minor. This action is obtained by setting DECOMP = 32. 9. Parallel sparse decomposition is selected with the NASTRAN statement keyword PARALLEL (or SYSTEM (107)). To obtain optimal performance, UGS also recommends that the SEQP module be used with parameter NEWSEQ = 2. Examples: 1. Solve [A][X] = [B]. DECOMP FBS MATPRN A/L,U,/ $ L,U,B/X/ $ X// $ 2.

Extract the diagonal elements of square matrix A into diagonal matrix B (if A is complex, extract only the real part) and raise the elements to the exponent POWER. Copy rectangular matrix A into rectangular matrix B and raise the elements to the exponent POWER. If A is complex and POWER<>1.0, extract only the real part. However, if POWER=1.0, B contains the magnitude of the elements. ‘SQUARE’ ’WHOLE’ POWER Input-real single precision-default=1. Exponent to which the real part of each element is raised. See Remarks. Remarks: 1. OPT = ’COLUMN’ or ’SQUARE’ provides exactly the same functions, except that the output using COLUMN is a vector, and the output using SQUARE is a square diagonal matrix. Both options process only the real part of the diagonal terms of the input matrix. If POWER = 0, unit column or the identity matrix of the dimension of the input matrix is produced. This is an efficient method for producing these useful DMAP tools. OPT = ’WHOLE’ operates on all terms of the input matrix to produce an output matrix of the same dimension. Sparse factor matrices (form = 11, 13, or 15) are not supported with OPT = ’WHOLE’. Each term is processed independently. 9-102 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements 2. OPT = ’WHOLE’ operates on all terms of the input matrix to produce an output matrix of the same dimension. Sparse factor matrices (form = 11, 13, or 15) are not supported with OPT = ’WHOLE’. Each term is processed independently. If POWER = 0, all nonzero terms of [A] produce unit terms in [B]. Zero terms in [A] produces zero terms in [B]. This is a means for producing Boolean matrices. [A] can be either real or complex. If POWER = 1.0, [B] is a real matrix with terms that are the absolute value of the terms of [A]. If [A] is complex, [B] contains the magnitude of the terms of [A]. 3. For fractional values of POWER and OPT = ’WHOLE’, all elements must be nonnegative. For OPT = ’COLUMN’ or ’SQUARE’ all diagonal elements must be nonnegative. 4. For whole number values of POWER, only real [A] matrices are allowed. The sign of the terms of [A] are properly preserved. 5. If an illegal operation is requested, a warning message is produced, and [B] is purged. Examples: 1.

Number of columns (that is; subcases, modes, time steps or frequencies) desired in the output matrices. By default, all data records are converted into the output matrices. If NCOL is less than the number of data records in the input table, the first NCOL records are converted and the remaining records are ignored. Input-integer-default=1.

DRMH1 is a similar to the DRMS1 module except that only the linear quantities (for example, axial stress) are output to the matrix. However, if NULLROW=0, null rows are inserted for the nonlinear quantities (for example, margin-of-safety). 2. DRMH1 converts tables with complex numbers to a matrix. However, the matrix contains complex numbers. As a result, only the item codes specified in the real side of the plot code tables are utilized. 3.

Mode acceleration based displacement matrix flag. If DTMi<>0, MOPFi is a mode acceleration based displacement matrix and, therefore, velocities and accelerations are not output to OFPi. For APP=‘TRANRESP‘, MOFPi must have only one column per time step instead of the usual three. Remarks: 1. If CASECC is purged, all input data blocks are converted. Otherwise, the inputs are converted based on the output commands specified in CASECC. 2. If the number of entries in a matrix does not match the associated table, the following occurs: If the number of rows (output quantities; for example, stresses) does not match, a warning message is printed with the identification of the matrix and table name. If the number of columns (for example, subcases or mode) does not match, a warning message is printed and the module continues. This allows you to combine modal results using any desired method into a single set of results (or more) and not be required to modify the table.

If NCOL is less than the number of data records in the input table, the first NCOL records are converted and the remaining records are ignored. Remarks: 1. SDR2 output data blocks (OFPi) are input data blocks for this module. Module DRMS1 generates the output transformation matrix (MOFPi) and associated directory table (TOFPi) from each of the input data blocks. 2. There are some data in OFPi for the output transformation that cannot be given linear combination operations, such as margins of safety and principal stresses. This irrelevant data is eliminated from the output transformation matrix. Components that are retained in the matrix MOFPi are indicated in the table of element stress output data description. 3. All the output transformation matrices have as many columns as the number of modes or loading conditions specified in PARAM, NCOL. Each column contains all the relevant components of GRIDs (T1, T2, and so on) or elements (σx, σy, and so on) for all the GRIDs or elements retained in the input data blocks. 4. Directory tables contain the mapping information as follows: • RECORD 0 - Header record, indicating: – – • Type of data (φ, q, σ, or F) Format code (real, real/imaginary or magnitude/phase) RECORD 1 - Identification of the columns, providing: – – Column numbers of the associated matrix Natural frequencies (fn) • RECORD 2 - Identification of the rows, providing: – – – – Type code of points or elements ID number of points or elements Number of components of the point or element retained in the associated matrix Starting row number of the point or element with reference to the associated matrix.

The main purpose of module DSABO is to prepare tables that generate a new stiffness matrix, mass matrix, load vector, and so on, while taking into account the design variable perturbations, that is, K + DELTAK, M + DELTAM, and so on. These calculations are completed by generating an EST for all elements. These ESTs are referred to by the design variables and are in the same ascending order as the original EST. The EPT portion of the generated EST includes all the perturbations necessary to build K + DELTAK, M + DELTAM, and so on. EMG and SSG1 use ESTDV to generate K + DELTAK, M + DELTAM and P + DELTAP due to temperature effects. DSVG1 and DSVG2 then calculate DELTAK * u, DELTAP and so on. 2. If central difference is requested, DSABO must be executed for the backward tables.

Remarks: 1. The main purpose of the EQUIVX is to save either storage space or l/O time or both. 2. If DBP and DBS reside on different DBsets and PARM < 0, a copy of DBP is made to the DBset on which DBS resides. The equivalence flag is broken and the data blocks become separate. These rules apply only if the secondary data block resides on a permanent DBset or DBS is not referenced on a TYPE DB statement and its DBset is a scratch DBset. Therefore, UGS recommends that DBS is referenced on a TYPE statement and defined in the NDDL sequence with its location assigned to the scratch DBset. 3.

If the EQUIVX.../DBS statement is executed only once and is not re-executed in the DMAP loop, the message can be safely ignored. However, if the EQUIVX statement is potentially re-executed, it should be replaced with the DELETE and COPY module.

FBTYP Input-integer-default = 0. Forward or backward pass selection. -1 0 1 Perform backward pass only. Perform forward and backward passes (default). Perform forward pass only. Remarks: 1. FBS employs one of two methods – sparse or non-sparse – based on the decomposition method used by DCMP or DECOMP in computing the factor matrices. For example, if sparse methods were used to compute the factors, FBS uses the sparse method. The default decomposition and FBS method is sparse. There are also submethods (FBSOPT<>0) which apply only to non-sparse methods and are ignored for sparse methods. See Remark 5. 2. Nonstandard triangular factor matrix data blocks are used to improve the efficiency of the backward substitution process. 3. Solutions with Cholesky factors are performed if the lower triangular factor matrices are form 10. 4. The diagonal factor of symmetric matrices is stored as the diagonal of [D]. When using the forward-pass only and backward-pass only options, [D] is included in the forward pass. 5. The keyword FBSOPT (or SYSTEM(70)) on the NASTRAN statement can be used for FBS method selection (non-sparse only). If the FBSOPT keyword is not used, the program selects the FBS method, which results in the lower sum of CPU and I/O time. FBSOPT -2 -1 0 +1 Non-sparse submethod selection Method 1A Method 1 Automatic selection method based on minimum of l/O + CPU time Method 2 NX Nastran DMAP Programmer’s Guide 9-211 Chapter 9 Descriptions of DMAP Modules and Statements 6. The equation for forward-only solution is [L][X] = ±[B], and for backward-only the solution is [L]T[X] = ±[B]. Both are right-hand solutions. 7. Left-hand solutions (KSYM = 2) are available for factors of symmetric or unsymmetric matrices. Also, the NASTRAN keyword FBSLEFT=n or SYSTEM(72)=n in the FMS section, or PUTSYS(n,72) in the DMAP sequence, specifies the transpose flag on [B]: If n=0, FBS solves [L][U] = ±[BT. If n=1, FBS solves [X]T[L][U] = ±[B]T. 8. Parallel processing in this module (Method 1A only) is selected with the NASTRAN statement keyword PARALLEL (or SYSTEM (107)). To force parallel processing, also specify NASTRAN FBSOPT = -2, SPARSE = 0. 9. For the sparse method, the B matrix must be in machine precision. See Remarks under the “DECOMP” module description. 10. See the NX Nastran Numerical Methods User’s Guide for further details on the FBS module and related topics. Examples: 1. Solve [A] [X] = [B] where [A] can be either symmetric or unsymmetric. DECOMP FBS MATPRN A/LD,U, $ LD,U,B/X/ $ X// $ 2. Solve [A] [X] = [B] assuming [A] is symmetric (form = 6 in matrix trailer). DECOMP FBS MATPRN A/LD,, $ LD,,B/X/ $ X// $ 3.

Also allows a module to append other data blocks to DBi on successive passes through a DMAP loop. Allows a data block to be overwritten Remarks: 1. FILE is a nonexecutable DMAP instruction that is used only by the DMAP compiler for information purposes. It can appear anywhere in subDMAP. It is also a local declaration; that is, it must be declared in all subDMAPs where the SAVE, APPEND, or OVRWRT is needed. 2. A data block name can appear only once in all FILE statements within a subDMAP; otherwise, the first appearance determines all special characteristics applied to the data block. 3. The APPEND keyword should only be applied to local scratch data blocks. In other words, the data block should not be referenced on a TYPE DB statement. UGS also recommends that the APPEND keyword not be applied to data blocks that appear as output on the EQUIVX module. See the “EQUIVX” module description for further details. Example: 1. Data block C is created only in the first pass through the loop and must be "saved" for subsequent passes. FILE C=SAVE $ TYPE PARM,,CS,N,R=(1.,0.) $ TYPE PARM,,I,N,COUNT=1 $ . . .

MEDGE must be present if p-elements are present. 2. GPWG is identical to Option 7 in the VECPLOT module. 3. GPWG calculates the masses, centers of gravity, and inertias of the general mathematical model of the structure. The data are extracted from the [Mgg] matrix by using a rigid body transformation calculation. The transformation is defined by the global coordinate displacements resulting from unit translations and rotations of the whole body about a reference point. 9-254 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements 4. Because of the scalar mass effects, the total mass can have directional properties, and the center of gravity cannot be a unique location. This effect is shown in the output by giving for each of the three masses, its own direction and center of gravity. The inertia terms are calculated by using the directional mass effects. The axes about which the inertia terms are calculated cannot intersect. However, these axes are those which provide uncoupled rotation and translation effects. This is the significance of the term "center of gravity". If the structural model has been constructed using only real masses, the three masses printed out are equal, the center of gravity is unique, and the axes of the inertia terms intersect at the center of gravity. 9.163 GUST Computes loads for aerodynamic analysis Computes loads for aerodynamic analysis that are associated with aerodynamic flow.

Input-real-default=0.0. Dynamic pressure. Remarks: 1. If DIT is purged, GUST returns (setting NOGUST = - 1). 2. CSTMA can be purged. 3. Often the shape (time dependence) of the gust is unknown, except for certain statistical information, for example, power spectral density and RMS value. In these cases, the GUST module must create frequency-dependent loads. Sometimes the gust shape is specified as a function of time, which is analyzed by Fourier transform techniques. Then the frequency dependent loads are calculated by Fourier transform. The value of the load is calculated from the downwash distribution. The calculation involves the aerodynamic formulation. For all methods (except strip theory) the downwash is a part of the aerodynamic theory used in the AMG-AMP modules. The downwash is associated with the j-set, which corresponds to the Ajj matrix. The loads are computed from the downwash using aerodynamic matrices. The downwash to be provided comes from a simple model of the atmosphere. The velocity is vertical (in the z-direction of the aerodynamic coordinate system), and appears (to an observer) in the airplane coordinates to sweep back toward the +x direction. This implies that the downwash vector has two properties: It is proportional to the cosine of the dihedral angle for any panel. There is a time delay of amount X/U for the arrival at any point. (X is streamwise coordinate.) 9.164 IFP Reads Bulk Data Section Reads in the Bulk Data and outputs the finite element model in table form. 9-256 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Format: IFP BULK/ GEOM1,EPT,MPT,EDT,DIT,DYNAMIC,GEOM2, GEOM3,GEOM4,EPTA,UNUSED11,MATPOOL,AXIC,PVT,DMI, DMINDX,DTI,DTINDX,DEFUSET,EDOM,DEQATN,DEQIND, CONTACT,OINT,UNUSED25/ S,N,NOGOIFP/S,N,RUNIFP3/S,N,RUNIFP4/ S,N,RUNIFP5/S,N,RUNIFP6/S,N,RUNIFP7/S,N,RUNIFP8/ S,N,RUNIFP9/SEID/S,N,RUNMEPT $ Input Data Block: BULK Table of all Bulk Data entries Output Data Blocks: GEOM1 EPT MPT EDT Table of Bulk Data entry images related to geometry Table of Bulk Data entry images related to element properties Table of Bulk Data entry images related to material properties Table of Bulk Data entry images related to element deformation, aerodynamics, p-element analysis, divergence analysis, and the iterative solver.

Note that the output data block sequence A,B,,, is the same as ,A,,B, or ,,,A,B. 2. UGS recommends using the ASSIGN FMS statement for assigning the FORTRAN unit. Certain FORTRAN units are reserved, see “Making File Assignments” in the NX Nastran Installation and Operations Guide for a listing of reserved FORTRAN units. 3. Data blocks are read from the FORTRAN unit in either binary or neutral format, depending upon the FORM option of the ASSIGN FMS statement. If no ASSIGN FMS statement is specified, binary input is assumed. 4. The format of the FORTRAN binary file is given in the OUTPUT2 description 5. Factor matrices (forms 4, 5, 10, 11, 13 and 15) cannot be processed by INPUTT2. 9.176 INPUTT4 Inputs a matrix from a FORTRAN unit Reads an ASCII or binary file from a FORTRAN unit and creates a matrix suitable for input to other modules.

Each matrix is read from IUNIT according to its ASSIGN FMS statement, and the BIGMAT as shown in the remarks of the OUTPUT4 description. 2. Each real or complex matrix must have been written on IUNIT according to the format below. • For example, in the nonsparse format and binary format (ASSIGN FORM=UNFORMATTED), each matrix can be created (assumed on FORTRAN unit 8) as follows: Record 1-four word record WRITE(8) NCOL,NROW,NF,NTYPE Record 2,3,and so on WRITE(8) ICOL,IROW,NW,(X(I),I=1,NW) • If the ASCII format (ASSIGN FORM=FORMATTED) and the nonsparse format is desired, each matrix must be created as follows: Record 1 100 WRITE(8,100) NCOL,NROW,NF,NTYPE FORMAT(4I8) Record 2,3, and so on 200 WRITE(8,200) ICOL,IROW,NW,(X(I),I=1,NW) FORMAT(3I8,(1P,5E16.9)) The format for X(I) above must be (1P,rEw.d), where d is the number of digits in the fractional part, w must be greater than d+7, and r is the integer part of 80/w. NX Nastran DMAP Programmer’s Guide 9-273 Chapter 9 Descriptions of DMAP Modules and Statements • The NX Nastran "util" directory contains a utility subroutine called MAKIDS in a file called mattst.f (or .for) which writes a matrix into the format suitable for INPUTT4. (See the NX Nastran Installation and Operations Guide.) Zero terms must be explicitly present from the first nonzero in any column to the last nonzero term unless the sparse matrix option is used. Null columns need not be input (they are properly handled if they are input). • • 3. UGS recommends using the ASSIGN FMS statement for assigning the FORTRAN unit. Selection of a proper value for IUNIT is machine dependent. If the ASSIGN statement is not provided, the format of the matrices on IUNIT is assumed to be nonsparse and binary. The ASCII format requires an ASSIGN FMS statement with the FORM = FORMATTED option. Certain FORTRAN units are reserved. (See the NX Nastran Installation and Operations Guide for a listing of reserved FORTRAN units.) 4. The memory required is from the first nonzero entry in the column to the last nonzero entry. 5. Factor matrices from DECOMP and DCMP (matrix forms 4, 5, 10, 11, 13, and 15) cannot be processed by INPUTT4. 6.

The external program can be either a shell script or an executable program. It can either mimic an internal module or provide any user-defined functionality that requires access to NX Nastran‘s data structures. 2. NX Nastran remains in a "wait" state until the external program is completed. 3. OUTPUT2, OUTPUT4, INPUTT2 and INPUTT4 modules are required to pass tables and/or matrices into the external program. 4. ISHELL capability is supported on UNIX platforms only. 5. The name of external program must be uppercase and limited to 8 characters. 6. The unit numbers must have associated ASSIGN statements. Based on the ASSIGN statements, the module automatically passes the physical filenames associated with unit numbers to the external program. These filenames are passed at positions 31 through 34. 7. Errors encountered in ISHELL do not terminate the NX Nastran execution. 8. IRTN=-1 indicates a failure during invocation of PRGNAME. It is not related to errors encountered within the invoked script or executable. For example, PRGNAME cannot be found or does not have execute permission. 9. You need a utility program to parse the arguments for your external program. For example, use set -A argarray "$@" or a similar technique. 10.

SYM < 0, {CP} is used for {RP}. SYM ≥ 0, {CP} and {RP} are distinct. Input-integer-default=0. Type of [A]. If TYPE is 0, the type of the output matrix is the maximum type of [A11], [A21], [A12], and [A22]. Input-integer-default=0. Form of [A]. (See Remark 3.) Remarks: 1. MERGE is the inverse of PARTN in the sense that if [A11], [A12], [A21], [A22] are produced by PARTN using {RP}, {CP}, FORM, SYM and TYPE from [A], MERGE produces [A]. The operation of MERGE is dependent upon the partitioning vectors, {CP} and {RP}, and the symmetry flag, SYM. Figure 9-5. Let [A] be an m by n matrix, {CP} be an nx1 vector containing q zero elements; and {RP} be a mx1 vector containing p zero elements. Partition [A11] consists of all elements Aij of [A] for which CPj = RPi = 0.0 in the same order as they appear in [A]. Partition [A12] consists of all elements Aij of [A] for which CPj≠ 0.0 and RPi = 0.0 in the same order as they appear in [A]. Partition [A21] consists of all elements Aij of [A] for which CPj = 0.0 and RPi ≠ 0.0 in the same order as they appear in [A].

The MPYAD keyword (or SYSTEM(66)) and the SPARSE keyword (or SYSTEM(126)) on the NASTRAN statement is used for MPYAD method deselection. (The SPARSE keyword is described in Remark 11.) The Deselection Values in the table below are used to deselect or disable a single method or several methods. If MPYAD=0 and SPARSE=1, which are the defaults, the method that results in the lowest CPU and I/O time is selected. If all transpose methods are deselected, T must be equal to zero (default). If all nontranspose methods are deselected, T must be equal to 1.

For example, NASTRAN MPYAD = 243 (which is obtained from 255-(4+8)) selects only Methods 2 Transpose and Nontranspose. For Method 1 Submethods (storage techniques), a combination of methods is selected accordingly. First, sum their Deselection Values then add 1 (if Nontranspose) and/or 2 (if Transpose). This total is then subtracted from 262143. See examples below. Example 1: If only Method l Nontranspose with storage techniques D, E, and F are desired, NASTRAN MPYAD=247806 (which is obtained from 262143-(2048 + 4096 + 8192 + 1)). If Method 2 is also desired in Example 1, NASTRAN MPYAD=247794 (which is obtained from 262143-(2048 + 4096 + 8192 + 8 + 4 + 1)). • Example 2: 8. As an alternative to the deselection procedure described above, the MPYAD keyword value can be set to select a single method while deselecting all other methods and submethods. To select a single method, add 1048576 to the selection value of the desired method shown in the table below. For example, if Method 1 Nontranspose Storage Submethod C is desired, MPYAD = 1048586; computed from 1048576 + 10. 9-388 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Method Method 1 Nontranspose 1 Transpose 2 Nontranspose 2 Transpose 3 Nontranspose 3 Transpose 4 Nontranspose 4 Transpose 1 Nontranspose 1 Nontranspose 1 Nontranspose 1 Nontranspose 1 Nontranspose 1 Nontranspose 1 Transpose 1 Transpose 1 Transpose 1 Transpose Storage submethod StorageSubmethod 1 1 — — — — — — A B C D E F A B C D Selection value SelectionValue 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 If a Storage Submethod under Method 1 is selected in this manner, a printout of timing estimates for the other submethods can be requested by adding 3145728 to the selection value above. Using the previous example, MPYAD = 3145738, computed from 3145728 + 10. 9. Sparse methods are deselected or selected by the SPARSE keyword (or SYSTEM(126)) on the NASTRAN statement. The default SPARSE = 1 causes the automatic selection of sparse methods if their CPU and I/O estimates are lower than those estimated for the methods in Remark 7. If the sparse method is not desired, specify SPARSE = 0 or 6. • In order to select or force one or both methods below, add l to its value(s) below.

To force the sparse methods, specify SPARSE = 7, computed from 1 + 2 + 4. Note that if SPARSE = 2, 3, 4, 5, or 7, all methods in Remark 2 are turned off or deselected, and the MPYAD keyword must be equal to zero. • The SPARSE keyword is also used for sparse method selection within all modules which perform matrix decomposition and forward-backward substitution; for example, DCMP, DECOMP, FBS, and SOLVE. 10. The diagonal matrix format (FORM = 3) for input matrices is not supported for the transpose option (T = 1), and causes an “ILLEGAL INPUT” fatal message. [A] can be transposed with the TRNSP module. 11. Parallel processing in this module (Methods 1 Nontranspose Storage E and Transpose Storage C only) is selected with the NASTRAN statement keyword PARALLEL (or SYSTEM(107)) which is set to the number of parallel processors (default = 0).

Any or all of the input data blocks can be purged. 9-424 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Parameters: ITAPE Input-integer-default=0. ITAPE is used to select the file positioning option as follows: +n 0 -1 -3 -9 IUNIT Skip forward n data blocks before writing (used only if file has no label). Data blocks are written starting at the current position. If this is the first use, no label is written. Rewind IUNIT before writing, and label file. Rewind IUNIT, print data block names and write after the last data block on IUNIT (file must have a label). Write a final EOF on IUNIT (must be used before -3 option and as last I/O use of unit), then rewind IUNIT. Input-integer-no default. IUNIT is the FORTRAN unit number on which the data blocks are to be written. UGS does not recommend IUNIT=0. See Remark 7. Input-character-default = ‘XXXXXXXX’ LABL is used for file identification. The label is written only if ITAPE=-1, and is checked only if ITAPE=-3. Input-integer-default=2 * BUFFS IZE words. Maximum physical record size. (See Remarks.) Input-character-default=blank. NDDL names corresponding to DB1 through DB5. If DBi is a matrix, the corresponding NDDLNAMi is ‘MATRIX’ (See Remarks.) LABL MAXR NDDLNAMi Remarks: 1. A data block (table or matrix) consists of logical records: • In matrices, each column is contained in one logical record. Each record begins with the row position of the first nonzero term in the column followed by the first through the last nonzero term in the column. In tables, the contents of logical records vary according to the table but are described in the data block descriptions. • 2. The FORTRAN binary file consists of physical records of data from the data block and KEYs that are provided to assist in the reading of the file. Each physical record of data is separated by one-word records called KEYs. The KEYs indicates one of the following depending on its location in the binary file: KEY >0 Description The length of the next physical record. It can also indicate the start of a new logical record. NX Nastran DMAP Programmer’s Guide 9-425 Chapter 9 Descriptions of DMAP Modules and Statements KEY 0 <0 Description End-of-File (data block) (EOF) or End-of-Data (EOD) End-of-Logical record (EOR) or a null column. The absolute value indicates the logical record number. 3. The End-of-Data (EOD) follows the last end-of-file (data block) written to the binary file. 4. If possible, each logical record of the data block is written to one physical record of the FORTRAN binary file. However, the length of a logical record can exceed the maximum length of a physical record (see MAXR parameter). If this occurs, the logical record spans more than one physical record. In other words, the logical record is written to the first physical record followed by a positive KEY record, which indicates a continuation of the logical record and the length of the subsequent second physical record. 5. The OUTPUT4 module performs similar operations on matrices, but not tables. It is simpler to use and is the recommended method for matrix output. 6. Tables and matrices can be processed as sequential data blocks. 7. UGS recommends the ASSIGN FMS statement (in the NX Nastran Quick Reference Guide) for assigning the FORTRAN unit. Selection of a proper value for IUNIT is machine dependent. See “Making File Assignments” in the NX Nastran Installation and Operations Guide. 8. No physical record exceeds the value specified by the parameter MAXR, which has a default that is two times BUFFSIZE words. Furthermore, the value specified for MAXR should not exceed the maximum allowable record size for the receiving disk device. See “Keywords” in the NX Nastran Installation and Operations Guide for the maximum allowable values. 9. When the neutral format option is selected via FORM=FORMATTED or an endianness conversion is selected via FORM=LITTLEENDIAN or FORM=BIGENDIAN on the ASSIGN FMS statement (associated with OUTPUT2 parameter IUNIT), MAXR and NDDLNAMi are interpreted as follows: Represents the maximum physical record size (in words) on the target machine(s) for the machine binary-formatted file. For neutral files, this applies to the binary file after it has been converted from neutral to binary via the supplied conversion utility RCOUT2. Correlates the DMAP data block name with the corresponding NDDL-defined name. If this parameter is left blank, the corresponding DMAP name (DB1 through DB5) is assumed to be the NDDL-defined name. MAXR NDDLNAMi The following is a partial list of the table data block names available for OUTPUT2 neutral file formatting. For a more complete list see the NDDL.

If a matrix is not an NDDL data block, the NDDLNAMi=‘MATRIX’should be used. For example, to write the matrix MYMATRIX, use OUTPUT2 MYMATRIX,,,,//ITAPE/IUNIT/LABL/MAXR/‘MATRIX’$ Note that the neutral format is a machine-neutral format that allows the transfer of the OUTPUT2-generated files between different machine types. See “RCOUT2” in the NX Nastran Installation and Operations Guide for a discussion of this transfer process and the supplied conversion utility RCOUT2. 10.

OUTPUT2 files can be read using three utility subroutines provided in the utility ("util") directory. (See “Building and Using TABTST” in the NX Nastran Installation and Operations Guide. See Remark 12. IOPEN IHEADR IREAD Once per FORTRAN unit Once per data block As many times as desired These routines are contained in a file called tabtst.f (or.for). These routines are coded in machine-independent FORTRAN. Major benefits that result in using this standard interface are: • • • Easier initial usage of OUTPUT2. Most users make several errors while becoming familiar with the formats. User code is not burdened/concerned with physical record boundaries. Data can be processed in logical groups rather than in a "blast" read mode. Major limitations include: • • • Matrices cannot be processed in this manner. Multiple FORTRAN units cannot be simultaneously processed. BACKSPACE operations are not permitted. Following are descriptions and use of the three OUTPUT2 service routines. NX Nastran DMAP Programmer’s Guide 9-431 Chapter 9 Descriptions of DMAP Modules and Statements Entry point IOPEN Description Initializes an OUTPUT2 file and read the label (NX Nastran). Format: CALL IOPEN(IUN,L) where IUN = An input integer, which specifies the unit number to be read. L = An output two-word array (2A4) containing the label written on the unit (L comes from the third parameter in the DMAP call). Method: IOPEN rewinds IUN and reads in the data, title, and label. The keys are checked. A key check failure results in the message IOPEN BAD KEYX = XXXX. IHEADR Processes the data block name and trailer. Format: CALL IHEADR(IUN,NAM,T) where IUN = As described in IOPEN. NAM = An output two-word array (2A4) containing the data block trailer in words two through seven. Word one contains the location in the DMAP call (101,102, and so on) Method: IHEADR reads the name and trailer. It checks KEY lengths. It also skips the data block header (which unfortunately can contain data for some/few data blocks). IHEADR must be called for each data block either immediately after IOPEN or after IREAD signifies an end-of-file. Entry point IREAD Description Supplies data to the calling program in a logical (as opposed to a physical) manner. Format: CALL IREAD(IUN,ARRY,NARY,IMETH,NT,IRTN) where IUN is as described in IOPEN. ARRY is the array into which a record is transmitted. NARY is an integer input that requests the number of words to be transmitted. If NARY is zero, no words are transmitted. If NARY is negative, the words are skipped but not transmitted. If (NARY is greater than the number of words remaining, the remaining words are processed (skipped or transmitted) and NT is set to this number and IRTN is set to 1. 9-432 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Entry point Description IMETH is an integer input that specifies how to proceed through the logical record. If IMETH = 0, the current logical record is continuously processed until an end-of-record return (IRTN =1) is given. If IMETH = 1, the remaining data (if any) at the conclusion of IREAD, in the current logical record, is skipped. NT is an integer output value which contains the number of words transmitted or skipped if IRTN is 1 on return from IREAD. IRTN is an integer output value which indicates the status on return from IREAD. IRTN = 0 Normal return. IRTN = 1 End of logical record reached while trying to process NARY words. IRTN = 2 End-of-file reached for this data block. Method: OUTPUT2 physical records are read into a buffer area. These records are at most 2 * BUFFSIZE words long. The current position is maintained and data is transmitted (or skipped) from the buffer to the ARRY array. If the NX Nastran logical record spans several physical FORTRAN records, these are transparent (no end-of-record returns) to the user. 12. If you select any of the options for endianness using the ASSIGN FMS statement, the resulting files are fortran readable only on systems that have the same endianness. 9.242 OUTPUT4 Output matrices onto a FORTRAN readable file Write matrices in ASCII or binary format onto a FORTRAN readable file. Format: OUTPUT4 M1,M2,M3,M4,M5//ITAPE/IUNIT/UNUSED3/BIGMAT/DIGITS $ Input Data Blocks: Mi Matrices. Mi cannot be a factor matrix (forms 4, 5, 10, 11, 13, and 15). Parameters: ITAPE Input-integer-default = -1. ITAPE controls the status of the unit before OUTPUT4 starts to write any matrices as follows: NX Nastran DMAP Programmer’s Guide 9-433 Chapter 9 Descriptions of DMAP Modules and Statements ITAPE 0 -1 -2 -3 IUNIT ACTION None Rewind IUNIT before Write. End File and Rewind IUNIT after Write. Both Input-integer-no default. The absolute value of IUNIT is the FORTRAN unit number on which the matrices are written. If IUNIT is negative, the sparse output option is used, which means that only nonzero items in the matrix are written to the unit. UGS does not recommend IUNIT = 0. See Remark 1. Input-integer-default=1. Unused. UNUSED3 BIGMAT Input-logical-default=FALSE. BIGMAT is applicable only when IUNIT < 0. BIGMAT=FALSE selects the format that uses a string header as described under Remark 1. However, if the matrix has more than 65535 rows, BIGMAT is automatically set to TRUE regardless of the value specified. Input-integer-default = 9. DIGITS is the requested number of digits for the fractional part of the real values written for the ASCII format option (FORMATTED on the ASSIGN FMS statement). The FORTRAN Format Specification used internally by OUTPUT4 to write real values is formed as follows: FORTRAN Format Specification: P,rEw.d d = DIGITS w = d + 7 r = 80/w (integer portion) DIGITS For example, if DIGITS = 9, the format is 1P,5E16.9 or if DIGITS = 16, the format is 1P,3E23.16 Remarks: 1. Each matrix is written on IUNIT as follows: • Record 1: Word number 1 2 3 Type Integer Integer Integer Meaning Number of columns (NCOL) Number of rows (NR, if BIGMAT=TRUE, NR < 0) Form of matrix (NF).

The number of words in the column, NW (or string, L), is the number of elements in the column (or string) times the number of words per type. Number of words per type is given in the table below.

UGS recommends the ASSIGN FMS statement for assigning the FORTRAN unit (see “Making File Assignments” in the NX Nastran Installation and Operations Guide). Selection of a proper value for IUNlT is machine dependent. 5. If the nonsparse format (IUNIT > 0) is selected, zero terms are explicitly present after the first nonzero term in any column until the last nonzero term. 6. Null columns are not output. 7. An entire column must fit in memory. 8. The FORTRAN binary file option (FORM = UNFORMATTED on the ASSIGN FMS statement) is the preferred method when the file is to be used on the same computer. The ASCII format FORM = FORMATTED on the ASSIGN FMS statement allows use of the file on another computer type. 9. The output format of these files can be read by the INPUTT4 module. 10. OUTPUT4 files can be read using a utility FORTRAN subroutine called GETIDS, which is provided in the utility directory. (See “Building and Using MATTST ” in the NX Nastran Installation and Operations Guide.) GETIDS is in the file called mattst.f or mattst.for. The program must be modified if the ASCII format is desired. The program is designed to read matrices less than 65536 rows (BIGMAT = FALSE). 11. Sparse factor matrices (forms 4, 5, 10, 11, 13, and 15) cannot be processed by OUTPUT4. 12. If you select any of the options for endianness using the ASSIGN FMS statement, the resulting files are fortran readable only on systems having the same endianness. The only way to read these files on the same machines is to use the INPUTT4 command. 9.243 PARAML Sets parameters from a data block Format: PARAML DB/DBNAME/P1/S,N,P2/S,N,P3/S,N,P4/S,N,P5/S,N,P6/ S,N,SET1/S,N,F1/S,N,SET2/S,N,F2/ S,N,SET3/S,N,F3/S,N,SET4/S,N,F4/ S,N,SET5/S,N,F5/S,N,SET6/S,N,F6/ S,N,SET7/S,N,F7/S,N,SET8/S,N,F8/ S,N,SET9/S,N,F9/S,N,SET10/S,N,F10/ S,N,SET11/S,N,F11/S,N,SET12/S,N,F12 $ 9-438 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Input Data Block: DB Any matrix or table Output Data Block: DBNAME Any data block.

In the READ module, the most memory-intensive part of the calculations is involved with symbolic decomposition of the mass or shifted stiffness matrix. Two methods of internal resequencing are available. When the USET, SIL, EQEXIN, and PARTVEC data blocks and SETNAME parameter are available, the resequencing is done in a grid point basis. These data blocks allow correlation of row numbers in the a-set with grid point numbers. When any of these data blocks are missing, the resequencing is done on a degree-of-freedom basis, potentially 6 times larger in size and requiring the square of this quantity for memory. The grid point option requires less memory and is appreciably faster than the degree-of-freedom option. 3. In all eigensolution methods, READ calculates rigid body modes accurately without the presence of SUPORTi entries in the Bulk Data section. The SUPORTi entries define the r-set, the reference set for rigid body modes. If all of the input blocks associated with the r-set are input properly, the static shapes input in the DAR data block are used to compute rigid body modes. If the calculated frequencies associated with these modes are small numbers, they are reset to binary zero. • Modern r-set introduced in Version 70.5: DXR has the same number of rows as KXX and both are partitioned from DAR and KAA using PARTVEC. DAR is the motion of the a-set variables due to unit motion of each r-set point, successively, as calculated by static analysis and ignoring mass effects. Linear combinations of these shapes are used for rigid body mode shapes that are orthogonal with respect to the mass matrix.

DMX is partitioned from DM in the way KXX is partitioned from KAA. In other words, the same degrees-of-freedom are partitioned for both KXX and DMX. The modern method uses DAR instead, with the r-set rows included in DAR.

Provisions for it can be removed from the code in a future version. Refer to old documentation for a description of this obsolete form. 4. For the Lanczos and INV methods, KAA can be indefinite and MAA must be at least positive semidefinite. For the unmodified tridiagonal methods (for example, HOU) KAA can be indefinite, but MAA must be non-singular. For the modified and auto tridiagonal methods (for example, MHOU and AHOU), MAA can be singular when [KAA + lambda*MAA] is non-singular. Lambda is an internally calculated shift. The matrix sum is singular or approaches singularity only when the system contains massless mechanisms. A shaft model made with bar elements using point masses is an example of a system with a massless mechanism. The torsion DOFs are not constrained to ground, and the point masses provide no rotary inertia. See the MODERS subDMAP for the auto-omit DMAP steps used to remove rows and columns with null mass for the tridiagonal methods. This makes the modified methods more efficient, and removes some (but not all) possible causes of singularity in the mass matrix. 5. For the Lanczos and Sturm Inverse methods, LAMA and PHA can also be input if the APPEND mode is being used. 6. LAMA and OElGS are suitable for OFP output. 7. MI cannot be purged. 8. Parallel processing in this module (Householder method only) is selected with the NASTRAN statement keyword PARALLEL (or SYSTEM(107)). (See the NX Nastran Quick Reference Guide. 9. If an r-set is present and special processing of rigid body modes is desired, UGS recommends that DAR have the same number of rows as KAA. If not, either MR, USET, or VACOMP should be specified. 10. For more detailed information on parameters F1 through NORM, refer to the descriptions of the “EIGR” and “EIGRL” Bulk Data entries in the NX Nastran Quick Reference Guide. 11. For the Lanczos method: • By default, the Lanczos method uses sparse matrix methods. To use regular matrix methods, specify SPARSE = 1 on the NASTRAN statement or specify PUTSYS (126,1) just prior to the READ module. In vibration analysis, MAA must be positive semidefinite. In buckling analysis, KAA must be positive semidefinite. For either type of analysis, the other input matrix can be indefinite. Performance-enhancing options can be requested on system cells 193 through198. Use the NASTRAN statement or the PUTSYS DMAP statement. See the NX Nastran Numerical Methods User’s Guide. The Lanczos method was updated in Version 70.5 with several enhancements related to shift logic. However, if the Lanczos method in Version 70 is desired, specify NASTRAN SYSTEM(273)=1 in the File Management Section or PUTSYS(1,273) in the DMAP before the READ module. • • • NX Nastran DMAP Programmer’s Guide 9-477 Chapter 9 Descriptions of DMAP Modules and Statements • For maximum efficiency in the Lanczos method, UGS recommends that the USET, SIL, and EQEXIN data blocks and SETNAME parameters are specified. If the size of KAA is not the same as the size of the set indicated by SETNAME, PARTVEC should also be specified. 12. If SID=-2, NE is used to modify the ND parameter. ND is modified accordingly: ND*(1+NE/100) 13. For the Lanczos (METH=‘LAN‘) and Householder (METH=‘HOU‘, ‘MHOU‘, and ‘AHOU‘) methods, if the problem can fit into memory, a "QL" Householder eigensolution is performed. If the problem cannot fit in memory, the old method is used because the "QL" method does not have spill capability. The criterion for switching from the requested method to the "QL" method is controlled system cell 359 and the NE parameter. The default value for system cell 359 is 1 which means: • • if METH=‘LAN’is requested, the program automatically switches to AHOU when the size of the problem is less than or equal to NE. if METH=‘HOU‘, ‘MHOU‘, and ‘AHOU,’the program automatically switches to the "QL" solution if the problem fits in memory. Examples: 1. Suppose you have a matrix [A] for which you want to extract eigenvalues via the classical equation [A − λI] {u} = 0. Presuming that [A] is input via DMI Bulk Data entries and there is an EIGR or EIGRL Bulk Data entry that is selected in Case Control (METHOD), the following DMAP sequence is sufficient: PARAML MATGEN READ A//’TRAILER’/1/S,N,NCOLA $ ,/IDEN/1/NCOLA $ A,IDEN,,,DYNAMICS,,CASECC,,,,,,,,/LAMA,VECTOR,MI, OEIGS,/’MODES’/S,N,NEIGS/1 $ OFP LAMA,OEIGS//$ IF (NEIGS > -1) MATPRN VECTOR// $ 2.

Format: RESTART DB1,DB2,DLSTIN/DLSTOUT/ INVOKE/SPEXP/DPEXP/NDDLNAM $ 9-478 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Input Data Blocks: DBi DLSTIN Data blocks to be compared A list of data blocks and the associated pathnames. DLSTIN was built as DLSTOUT during prior executions of the RESTART module. DLSTIN is used to invoke the same restart dependencies, but with different qualifiers, as done during previous RESTART comparisons. Output Data Block: DLSTOUT A list of data blocks and associated pathnames defined from DB1 that were deleted during this execution of the RESTART module. If DLSTOUT is designated as an APPEND file, DLSTOUT contains the list of data blocks deleted (or marked for deletion during this) from prior executions of the module. Parameters: INVOKE Input-logical-default=FALSE. If INVOKE = TRUE, restart deletions are performed. If INVOKE = FALSE (default), no deletions are performed, but data blocks are marked within DLSTOUT. Input-integer-default=6. Single-precision tolerance exponent. Two single-precision numbers x and y are considered equal if SPEXP DBEXP Input-logical-default=12. Double-precision tolerance component. Two double-precision numbers, x and y are considered equal if NDDLNAM Input-character-default=’ ’ NDDL is the name of the DATABLK statement to use for a description in the comparison that overrides the name of DB1. Remarks: 1. Any or all input data blocks can be purged. 2. If DLSTIN is not purged, the DB1 and DB2 must be purged. 3. If DBI and DB2 are not purged, the DLSTIN must be purged. 4. If INVOKE = TRUE, RESTART also deletes data blocks according to the data dependencies. Only data blocks with the current values of qualifiers for the path given by DBi are deleted. If the paths of DBi and the path of the data block to be deleted differ, all intersecting qualifiers use the current value and the remaining nonintersecting qualifiers use the wildcard (*) to determine deletion.

IDIAG ≥ 4 send grid point statistics to .f06 file. IDIAG ≥ 5 not used. IDIAG ≥ 6 dump data read to .f06 file. Remarks: 1. If PARAM POST is not enabled, the output datablocks OUGV1MX, OEF1MX, and OES1MX are not written to the .op2 file. To send results to the .op2 file, you must supply the following alter: COMPILE SUBDMAP=SEDRCVR ALTER RMAXMIN OUTPUT2 OES1MX,OEF1MX,OUGV1MX,// \$ If PARAM POST is enabled, the default is to send the output datablocks to the .op2 file, but not the transient results OUGV1, OEF1 and OES1. To send the transient results to the .op2 file, you must add the following to your Bulk Data: PARAM, RMXTRAN,YES 2. Since you can use the RMAXMIN case control command only in SOL 12 and 112, you can provide a DMAP alter for other solution sequences to generate the output datablocks OUGV1MX, OEF1MX and OES1MX. 9.262 RMG2 Processes radiation exchange coefficients Processes radiation exchange coefficients to produce temperature heat flux transfer matrices.

In the geometry table option, SEQP generates SEQGP Bulk Data entries to be appended to the GEOM1 data block and/or written to the punch file. 2. In the matrix option, GPL, USET, and SIL are required for SEQOUT>0 and can be purged if SEQOUT=0. 3. UGS recommends SEQMETH=7 for sparse decomposition and sparse forward-backward substitution only. The assembly of stiffness, mass, and damping matrices by the EMA module can be less efficient under this option. Also, if there is insufficient memory available to perform sparse decomposition, regular decomposition is performed and regular decomposition is inefficient under this option. 4. SEQMETH=5, 6, or 7, resequencing is performed even if the CPU estimate is higher than for no resequencing. 5. For SEQMETH=8, the estimates are computed for two sequencing methods that are suitable for the decomposition method selected by the PARALLEL and SPARSE keywords on the NASTRAN statement. Also selects the sequencing method with the lowest estimate. The following table shows the suitable methods for each decomposition method. Decomposition method Non-sparse and non-parallel Parallel Sparse 6. Description of SUPER: • If PARAM,SUPER=0, all grid points from the connection table that are not part of the group currently being processed are deleted. This option provides for sequencing only the interior points of a superelement. If any superelements are present, the residual structure is not resequenced. If all of the grid points are in the residual structure, they are resequenced. If PARAM,SUPER=0 or 1, all grid points in the connection table are considered. This option provides for the recognition of passive columns. If PARAM,SUPER=2, all points that are connected to multipoint constraints (via MPC entries) or rigid elements (for example, the RBAR entry) are placed in a special group at the end of the sequence. This option also forces SEQMETH=6 and cannot be selected with other values of SEQMETH. This option is intended primarily for models that have many active columns due to MPCs or rigid elements; for example, a model with disjoint structures connected only by MPCs or rigid elements. See the NX Nastran Numerical Methods User’s Guide for a further discussion of sequencing operations. Suitable SEQMETH 1 and 4 2 and 5 6 and 7 • • 7. FACTOR is used as follows: SEQID = FACTOR * GRP + SEQ where SEQ is a generated sequence number and GRP is a group sequence number. 9-536 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements If GRP=0, use GRP(MAX)+1 where GRP(MAX) is the largest group sequence number previously processed. 8. START specifies that the input sequence is the sorted order of the grid point numbers including the effect of any SEQGP entries input by the user. A single SEQGP entry can be input to select the starting point for the new sequence. Otherwise, the first point of lowest connectivity is used as the starting point 9. PSEQOPT has the following values and actions: • PSEQOPT=‘APPEND’ The list of all p-element grids at the bottom after all the regular grids. APPEND is intended for p-element analysis with p-version preconditioning, that is, SEQMETH = 5, 6 or 7. PSEQOPT=‘INSERT’ Insert the p-element grids in appropriate locations immediately after the regular grid point to which they are associated, which is the default in p-element analysis. INSERT is intended for p-element analysis without p-version preconditioning, that is, SEQMETH = -1, 1, 2, 3 or 4. • Example: The following example generates a mapping matrix (SEQMAP) to resequence the matrix KAA. The following SMPYAD module resequences the rows and columns of KAA. Following the decomposition of the resequenced matrix (KAAX), the MPYAD resequences the right-hand side (PA) and FBS performs the forward/backward substitution on the resequenced right-hand side (PAX).

Integer-input-default=0. Form of the X matrix. If FORM is zero, the form of [X] is 1 if the result is square, 2 otherwise. If [X] is known to be symmetric from physical principles, FORM can be set to 6. Remarks: 1. Except for the final product, all intermediate matrix products are computed in machine precision. NX Nastran DMAP Programmer’s Guide 9-539 Chapter 9 Descriptions of DMAP Modules and Statements 2. The matrices are post-multiplied from right to left; that is, the first product calculated is the product of matrix n-1 and matrix n. This implies that all purged inputs must be to the right. If the transpose flag is set for the last unpurged matrix, it is ignored without warning. 3. If the input matrices are incommensurate (for example, if the number of columns in A is not equal to the number of rows in B) or incompatible, the User Fatal Message 5423 “ATTEMPT TO MULTIPLY INCOMPATIBLE MATRICES” is issued. 4. The method used by this module is the same as for the MPYAD module except in case of a triple product, where [B] and [F] are symmetric and [A] = [C] and TA = 1; that is, [X] = [A]T[B][A] ± [F], a method that is more efficient than two equivalent MPYAD operations is employed. See Example 3. However, two equivalent MPYAD operations are selected automatically if two MPYADS are more efficient. (Two MPYADs can be forced by setting system cell 129 to 1, with PUTSYS(1,129) specified just before the SMPYAD module.) 5. If any of the matrices involved in the product do not exist, the module does not create any output. Examples: 1. Compute [X] = [A] [B]T [C] - [F]. SMPYAD A,B,C,,,F/X/3/1/-1/0/0/1 $ 2.

If OPT2 = 0,3 or 5 and TIMSIZ is supplied, TABPRT produces an estimation printout for each superelement except the residual structure. The equations used along with the semi-empirical constants are printed as well as dominant CPU time estimates, space estimates, and wall clock estimates. These estimates are valid for “large” superelements only and should be adjusted for anomalous characteristics. Estimate totals are also provided at the end of the SEMAP printout. If ESTDATA is also supplied, the constants of the estimating equations are adjusted. This technique is described on the Bulk Data entry DTI,ESTDATA. 3.

Identifies NDDL data blocks 2. Specifies the type and authorization of NDDL parameters, qualifiers, and location parameters 3. Specifies the type and authorization of local parameters The TYPE statement is a nonexecutable statement, but must appear before any NDDL data block, parameter, qualifier, or location parameter; or any local parameter that relies on the TYPE statement to identify its type and authorization. The TYPE statement has the following formats: Formats: 1. Data blocks: TYPE DB, dblist $ 2. NDDL parameters, qualifiers and location parameters: TYPE PARM, NDDL, ptype, 3. Local parameters: , prmlist $ TYPE PARM,,ptype, , prmlist = [default] $ 9-590 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements Describers: dblist ptype Description Integer Real single precision Real double precision Complex single precision Complex double precision Character Logical A list of NDDL data blocks.

Possible parameter types are as follows: ptype I RS RD CS CD CHARi, where i = 1-80 LOGICAL Remarks: N, Y Parameter authorization. Y allows user input of the parameter value via the PARAM Bulk Data entry or Case Control command. N disallows PARAM input. If neither N nor Y is specified, authorization or user override of the parameters contained in the prmlist are determined at DMAP compilation time by the parameter’s first appearance in a DMAP Module. A list of parameters. Each parameter must be separated by a comma or a space. In Format 3 only, parameters can be assigned a default value. This value overrides the MPL default value (if there are any). Character values must be enclosed in single quotation marks.

Parameters occurring in Assignment(=) statements must be defined in a previous DMAP module or TYPE statement. 2. A TYPE statement is required for a parameter if it appears first in one of the following instructions: • • • CALL MESSAGE Assignment NX Nastran DMAP Programmer’s Guide 9-591 Chapter 9 Descriptions of DMAP Modules and Statements • • Conditional (IF and DO WHILE) DBVlEW module (WHERE clause if its not a qualifier) 3. Default values for NDDL parameters and qualifiers are specified on the PARAM and QUAL NDDL statements and, if specified on the TYPE statement, result in a warning message. 4. With the exception of parameters declared as QUALifiers through the QUAL NDDL statement, all NDDL parameters are stored immediately in the database on completion of a DMAP assignment statement or the module S option. 5. As described under the CALL DMAP statement, the (S,) option to save control and QUALifier parameters is necessary to facilitate parallel and recursive processing. 6. Only the ptype is used on the TYPE PARM for parameters passed through a subDMAP argument list. Also, default values are ignored. 7. UGS recommends that all TYPE statements in a SUBDMAP appear immediately after the SUBDMAP statement. 8. If NDDL data blocks passed through a SUBDMAP argument list are referenced on a TYPE DB statement, a fatal error occurs. 9. If data blocks not defined in the NDDL appear in a TYPE DB statement, a fatal error occurs. 10. If the parameter type and authorization specified on a TYPE statement do not match those specified in a DMAP module, a fatal error occurs. 11. If the parameter type specified on a TYPE statement does not match the type required by a DMAP module, a fatal error occurs. 12. Character parameters which appear on TYPE statements and module instructions must be defined with ptype CHAR8. For example: TYPE PARM,,CHAR8,N,MAJOR,SETJ,COMP=‘COMP’$ MAJOR=‘G’$ SETJ=‘A’$ VEC USET/VGACOMP1/MAJOR/SETJ/COMP $ Use of other lengths, such as CHAR4, results in fatal termination.

In certain NX Nastran applications, the eigenvalue problem presented contains real, unsymmetric matrices. One such application, the direct structural acoustic problem is formulated as: where the stiffness and mass matrices are both real unsymmetric, containing coupled blocks of structural and fluid matrices. Another case of an unsymmetric but real eigenvalue problem is given in the aeroelastic divergence solution posed as: where Kll is the structural stiffness matrix, real, symmetric positive definite. However, the Qll divergence matrix is real, unsymmetric. 2. The left-handed solutions of the two problems presented before are: for acoustics and 9-594 NX Nastran DMAP Programmer’s Guide Descriptions of DMAP Modules and Statements for aeroelastic divergence.

SET1 or SET2, but not both, can be set to ‘COMP’(or blank) which means that one set is the complement of the other. For example, if MAJOR=‘G‘, SET1=‘A‘, and SET2=‘COMP’(or blank), SET2 is assumed to be those degrees-of-freedom in the g-set that are not in the a-set. 3. If SET1 and SET2 are unique subsets of MAJOR but their union does not comprise all of the degrees-of-freedom in the MAJOR set, the SET2 partition is assumed to be SET2=‘COMP’ For example, if MAJOR=‘G‘, SET1=‘A‘, and SET2=‘S‘, SET2 is assumed to be ‘COMP’(See Remark 2) and not just the s-set. 4. The set names MAJOR, SET1, and SET2, can specify a combination of set names separated by a plus (+) or minus (-) character. The plus (+) character indicates a union and the minus (-) character an exclusion. For example, ‘a-b+m’indicates the a-set without the b-set. This resultant set is then joined with the m-set. 5.

CARDNO is incremented by one for each line written to the punch file and is also written into columns 73-80 of each line. Output-integer-default=1. Set to 1 if XYPLOT is created; -1 otherwise. Input/output-integer-default=0. TABLED1 punch flag. If IDTAB is greater than zero, all requests for XYPUNCH produce TABLED1 Bulk Data entries for the curve. The table identification number starts at TABID and increases by one for each table punched. NOXYPLOT TABID Remarks: 1. OFPi2 can be element stresses, displacements, element forces, single-point forces of constraint, applied loads, slideline contact stresses, nonlinear loads in p-set, h-set, or d-set. 2. OFPi2 can be specified in any order. 3. If APP=‘RAND‘, PSDF and AUTO must be specified. 4. If APP=‘RSPEC,’OXRESP must be specified. 5. If APP=‘VG‘, OVG must be specified. Examples: 1.
