    Can you provide some details of the model setup? What is the analysis setup, how is excitation applied etc.

    My modal is a car, but the tire and suspension are simplify by spring element, and use an unit load as the excitation on one of the tire element (spring), then analysis by direct FRF which constrain under the car body, my intention is to found out the transmit relation of every part of the car(such as chair & suspension's transmit relation ).

    Please contact your local support office with your problem.

    Can you provide the model file?

    Hello,Greg

    Because the model is business secret, so i can't support the model, sorry !

    And my version of OptiStruct is 8.0.

    Thanks for your reply!
