MSC/NASTRAN
Writing an MSC/NASTRAN output file creates an MSC/NASTRAN file in ASCII format called filename.nas.
The following table lists the mesh elements written to the MSC/NASTRAN output file for the various mesh types and idealizations.

PGAP (properties)
Be aware that Pro/MECHANICA does not support or output thermal loads and constraints. Also, for gaps, stiffness properties are specified on the PGAP card. These properties include UO, the initial gap value, KA, the normal stiffness, and KT, the slide stiffness. MSC/NASTRAN supports zero-length idealizations—idealizations that have no length, such as an idealization between a point on a surface and the surface itself—for gaps and advanced springs only.
For an MSC/NASTRAN solution, you can use the fem_solver_time_limit config.pro option to interrupt the solver after the specified time limit. The default value is 60 (60 minutes).
If you place simulation entities on layers and want to review a file containing layer data, you can use the sim_output_ids_for_layers config.pro option to generate an XML file that lists the layers. Pro/MECHANICA outputs this file at the same time that it outputs the .nas file and places it in the same directory as the .nas file.
