    HI,

     

    OptiStruct this already with output of modal participation from MotionSolve, AVL/EXCITE, and SIMPACK.  You just need to get the modal participation results in .h3d, NASTRAN .inp4, or SDRC .unv file format.

     

    Please see:

    ASSIGN,EXCINP

    ASSIGN,H3DMBD

    ASSIGN,SIMPINP

    Hi Lokesh,

    Mode superposition method is widely used in civil engineering domain, where to reduce the computation and dynamic responses are estimated with very few Eigenmodes.

     

    You can get videos and books on the same. Please give a try on Google search,
