    Hi,

    We request you to see Radioss material library. At present Optistruct not have such material model to carry out Nonlinear modal frequency response analysis.
    See Optistruct & Radioss user guide for various material model.

    Hi Pratik,

     

    It may not be possible to do a modal frequency analysis with non linear material. with either OptiStruct or RADIOSS.
