    Refer Optistruct user guide & tutorial for Modal Analysis.Load collector with EIGRL card is needed to carryout modal analysis & same need to reference under loadstep Method Structure.By creating different load collector you can manage boundary condition.

    Hi Yukesh,

     

    What do you mean by 5 different constraints and same load?

     

    Is it like 5 different simulations? If this the case, you can create 5 different loadsteps.

     

    If you want to add different SPCs you can use SPCADD and use the same as SPC reference in loadstep
