Translating Matrix Data in an Abaqus SIM File to a Partial Nastran Bulk Data Text File

The Abaqus input data must be in a file with the extension .sim and must have been created with either a matrix generation or a substructure generation procedure. When you use the sim2dmig option, the execution procedure translates the matrix data to Nastran DMIG coefficients and creates a Nastran bulk data file with the extension .bdf.

Command Summary

abaqus tonastran  job job-name input input-file sim2dmig complex { YES NO }

Command Line Options

job

This option is used to specify the name of the Nastran bulk data file to be output by the translator. It is also the default name of the Abaqus file. Diagnostics created by the translator are written to a file named job-name.log.

input

This option is used to specify the name of the file containing the Abaqus data if it is different from job-name.

sim2dmig

This option is used to translate matrix data in an Abaqus .sim file into the Nastran bulk data file (.bdf) format.

complex

This option is used to determine how structural damping terms are represented. If complex=YES (default), structural damping terms are written as the imaginary part of the stiffness matrix; if complex=NO, structural damping terms are written as a separate real matrix.
