RE: CAE NX NASTRAN-103 SOLUTION: Modal mass sum and Modal mass effective fraction

Hello!,
This is very easy, simply enter in the nastran case control the command:
MEFFMASS(PLOT,GRID=0,FRACSUM,SUMMARY) = YES

You will get the modal mass sum and modal mass participation factor results written in the *.F06 output file:



Best regards,
Blas.
