Hello Users,
I am trying to apply a acceleration load to a one side fixed cantilever beam(shell element) to do frequency response analysis.
I tried 2 options.
1. I used DAREA in constraint and in Z direction constraint i used 5(Acclen Value). In Dload Panel, i changed it to Acceleration. It does not work. But, This method works for Load.(simply changed to Load option in DLOAD Panel)
2. I did nt use DAREA. I applied acclen as 5. It does not work.
Error says: Null excitation.
Thanks for any help.
