"Result File is in wrong format."

"Result File is in wrong format."

"Result File is in wrong format."

(OP)
Im doing modal analysis on a fixture I'm making. I'm using NX Nastran Sol 103 (real eigenvalues). I've run solutions with the same settings before on the same fixture, however I made a minor change to the fixture and now I obtain this error when trying to view my results.

I recreated an entire new simulation, idealized model and everything. Tries starting from scratch with the new fixture model and everything.

I've looked into things and I can't figure out why it's happening.

NOTE: Upon recommendation from support, I have Model Setup Check off and have added AUTOMPC to my parameters. I contacted support when trying to get the first revision to solve. I have tried changing these (although setup check shouldn't change the solution) to no avail.

RE: "Result File is in wrong format."

Hi handsupdb,

What error message is given? You will need to check the .f06 file after nastran solver terminates itself. In the .f06 file, search for the word "FATAL", that s the error message.

Kind regards,
Tuw
