Frequency Response: Mulitiple Load Cases not Allowed?

Frequency Response: Mulitiple Load Cases not Allowed?

Frequency Response: Mulitiple Load Cases not Allowed?

(OP)
I would like to create 3 load cases: base excitation in x, y, and z independently. Is there a reason why Femap does not allow load cases for frequency/harmonic response? It does not make much sense to me since you can do multiple load cases in a Random solution; either way the transfer functions need to be generated. I am using Femap 11.1.0 ... is this addressed in the newest release?

Thank you.
