George,
I appreciate the help. As it turned out, when the CAD model was exported from Solid Edge it changed the model from a surface to a solid, which created the issue you described. Thanks again.
If possible, would you be able to help with another issue? I've updated the model and I believe I have a decently working version. When ran in Radioss, it ends with 'Normal Termination', 0 Errors, and 0 Warnings, however the simulation ends fairly quickly and doesn't seem to any output data. I'm fairly certain there is some small error that I'm not recognizing due to inexperience.
For reference: There are 0 intersections and 0 penetrations, however there is a warning in the model checker: Boundary Condition Cards(1) -> Number of Boundary Conditions (1).
Additionally, it is outputting an .OUT, .RST, and .M00 file. I doubt that's relevant, however I'm listing it just to give full info. The .OUT file is attached if it helps any.
Again, I'm not sure what is going on as the simulation appears to not have many issues but is not outputting any data. My only guess is the definition of the rigid wall or boundary conditions is incorrect, however I have no evidence to believe so.
