Entries and Format

Entries recognized in the configuration file. The configuration file contained in the installation may be used as a template for other configuration files.

The format of the entries (with the exception of ELEMQUAL) is similar to the format of the I/O Options Entry in the input deck, namely:

ENTRY = Argument

Comments may be inserted using the $ character; which indicates that everything which follows on that line is a comment.

ELEMQUAL is a recognized entry in the configuration file. It is used as described in the Bulk Data Entry description ELEMQUAL with the condition that it must be written in free format (Bulk Data Guidelines).

Entry Argument Description
ASSIGN, UPDATE, filename Various See ASSIGN in the I/O Options Entry section.
BLOCKPARAM
<Parameter>
Parameters (with or without their specific values) can be specified for which the model should error out if these parameters are present in the input file. The ERROR message ID of the error which is printed is #1705.
<ERROR Message to be printed>
You can specify your own ERROR message text which should be included when the corresponding blocked parameters are encountered. The ERROR message text should be specified after the parameter name in the configuration file, and it should be preceded by “#”. The error message you specify is automatically formatted to within the standard 80 columns.

Example:

If the below line is included in the OptiStruct configuration file:
BLOCKPARAM,VMOPT,2 # This parameter is not recommended for our current use-case. 
Please switch the model to use PARAM,VMOPT,1 instead.
If the input file contains PARAM,VMOPT,2 (and the OptiStruct configuration file contains the above line), then the model will fail with the below ERROR:
*** ERROR # 1705 *** in the input data:
This parameter is not recommended for our current use-case. Please switch the
model to use PARAM,VMOPT,1 instead.
