Parasolid import error on the Patran discussion group which had the following response from MSC: Make sure that if you are running on NT then you start PATRAN on an NTFS disk partition.
If geometry is not associated to the FEM connecting element faces can be found by using the following tool: o In Patran -> Loads/BCs Tab o Create -> Total Load OR Pressure o Select Application Region, change to FEM, -> Auto Select o Select a reference face (such as one in a cylinder) and increase the tolerance for Adjacent Normals o Click Overwrite and then copy your list of element faces List to find associated nodes o Limitations:
Use caution when attempting to verify material orientations.
If nodes and element connectivity are absent from the Nastran results file, locate and comment out the following line in the input deck and re-run the job: PARAM,OGEOM,NO The parameter instructs Nastran to exclude model data from the results file.
This is an approach provided to a client for animating superelements in MSC Patran.
Start with a Tet-meshed solid model and do the following to apply a pressure load to specific faces on the Tet elements surrounding the hole: Loads/BCs->Create/Pressure/Element Uniform
Type in a "New Set Name" and select "Target Element Type = 3D"
Press the "Input Data" button, define a pressure load, and click OK.
Nastran solution subcases are selected from the Patran Results menu:

When performing a simple tet mesh, try using Patran's AutoTet mesher (it's actually pretty good).
