FEA Model Import and Export Functionality

Autodesk Nastran Editor

Autodesk Simulation Mechanical provides the following two types of Finite Element Analysis (FEA) interoperability with the Autodesk Nastran Editor. This program is automatically installed along with Simulation Mechanical:

Note: NEi / Autodesk Nastran conventions are used for models exported to the Nastran Editor or for results merged from the Nastran Editor. This differs from the treatment of models imported to or exported from a Nastran file using the third-party FEA support, which is based on MSC Nastran conventions.

Third-Party Finite Element Analysis (FEA) Applications

Autodesk Simulation Mechanical provides the following two types interoperability with various third-party FEA applications:

Note: You must complete the setup of the current model before exporting it. "Complete" means that the model is ready to be checked (Analysis Analysis Check Model) or analyzed (Analysis Analysis Run Simulation). Then, use either of these steps (Check Model or Run Simulation) to create the database files that are translated to the other FEA format. If the model is not at least checked, the Third-party FEA command will not be available (grayed out).

Autodesk Simulation Mechanical has the ability to import and/or export the following types of models:

File Type Import Export
ABAQUS INP Files, Version 5.3 Yes Yes
ANSYS ANS Files, Version 5.4 Yes Yes
ANSYS CDB Files, Version 5.5 Yes Yes
Autodesk Inventor Simulation Yes No
FEMAP Neutral Files (NEU), Version 6.0 Yes Yes
NASTRAN NAS, BDF and DAT Files, Version 2001 (MSC Nastran conventions are used) Yes Yes
NASTRAN OP2 files, Version 2001 (MSC Nastran conventions are used) Yes Yes 1
RecurDyn RFlex Input File (RIF) No Yes 2
PATRAN 2.5 Neutral Files (PAT) Yes Yes
SDRC I-DEAS Universal Files (UNV) Yes Yes
Stereolithography Files (STL) Yes No

1 Note: From the Results environment, use the Export All Results command and set the Save as type to NASTRAN Results(*.op2).

2 Note: From the Results environment, use the Export RecurDyn RFI command (Modal analyses only).
