Problem loading MSC Nastran 2013 f06 files in FEMAP

I am experiencing problems loading f06 files generated with MSC Nastran version 2013.1. FEMAP reads the output file, reports no errors, however no results set is created. That goes for all Linear Static (Sol 101), Nonlinear Static (Sol 106), and Modal (Sol 103) analyses I tested so far. However, importing op2 files generated in the same analysis run works fine, but I would like to work with f06 files for other reasons.

On the other hand, I can successfully import f06 files generated with MSC Nastran version 2012.2 for the same input deck.

Additionally, I observed that in some cases, manually changing the "<run_date> MSC Nastran <release_date> PAGE <page>" text to UPPERCASE (namely, "MSC NASTRAN") in the f06 files circumvents the problem.

Does anyone else have this problem? Is there a proper fix for this issue?

Re: Problem loading MSC Nastran 2013 f06 files in FEMAP

MSC changed the f06 file page headers between v2012 and v2013 which causes Femap to skip reading of the results.

This was corrected in Femap v11.3.0.
