Translating Nastran DMIG Data in Bulk Data Files to an Abaqus Binary SIM File

The translator from Nastran to Abaqus converts matrix data (DMIGs) to their equivalent in an Abaqus binary SIM file.

Overview

You can specify that the translator create a SIM file of matrix data in addition to a text input file. The matrix data can be translated to:

  • a SIM file structured as if it were created from a MATRIX GENERATE step in an Abaqus input file or
  • a SIM file equivalent to that resulting from an Abaqus analysis with a SUBSTRUCTURE GENERATE step.

Command Summary

abaqus fromnastran  job job-name input input-file dmig2sim { GENERIC SUBSTRUCTURE }

Command Line Options

job

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

input

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

dmig2sim

This option is used to write DMIG matrix data to a binary SIM file for further processing by Abaqus.

If dmig2sim=GENERIC, a SIM file with a generic matrix system equivalent to that produced by a MATRIX GENERATE step is created.

If dmig2sim=SUBSTRUCTURE, a SIM file with a substructure matrix system equivalent to that produced by a SUBSTRUCTURE GENERATE step is created.
