Hello everybody,

my question is: Is it possible to use superelement’s for modal analysis? I want to reduce a full vehicle model and just reenforce several areas. With the superelement i want to speed up the simulation time to try several strategies.

Thanks and regards

    Hi,

     

    yes, it is possible to use. Take a look for "

    Component Dynamic Analysis (CDSMETH) Superelement Generation

    " in OptiStruct help.
