Dear,
Is it possible to have 2 separate frequency analysis (different mass source - loads) in one run Let say eigen solution is to be use.
***NOTE: MASSES DEFINED UNDER LOAD# (last load case) WILL FORM THE FINAL MASS MATRIX FOR DYNAMIC ANALYSIS.
Best regards,
No. As of now you can only have one mass definition.
