After performing an EIGENVALUE Analysis using NX NASTRAN (SOL103) with the option set ATTACH TO RESULTS FILES under FILE > PREFERENCES > RESULTS then I see that the requested functions of modal mass participation factors are not imported in FEMAP model, any solution?, or should I have to repeat the analysis again, previously deactivating the option ATTACH TO RESULTS FILES?.
Solved! Go to Solution.
It works fine for me with Femap 11.4; have you checked f06 for errors and confirmed that the data is available in f06, it should have been printed in f06?
Sorry, my mistake, I can confirm that FEMAP is running OK, I have extracted 100 eigenvalues and the functions are created OK, thanks!.
