NX Nastran 5.0

NX Nastran 5.0

NX Nastran 5.0

(OP)
When I run the solver, the dos window comes up then promptly closes. I opened the log file I found in the folder and the last few lines are:

NX Nastran started  Mon May 11 09:41:35 EDT 2009

Looks like it cant open the file for whatever reason and so it closes the dos window. My question is are there any settings I should look at to resolve this? I had it working before. When I try to run the nastran solver on older sim files that ran fine before, I still get the same error.

RE: NX Nastran 5.0

... there was a April patch for this error  on nastran, contact Gtac...
