Hi,

 

Is it possible to do Modal analysis for rotor with shaft ( using 3D elements)  using following example in optistruct?. or it is applicable for only 1D elements problem?? I have tried . But it is not working for 3D problems

    Hi Arul,

    The OptiStruct rotor dynamics feature currently supports only 1D rotors. Rotor shafts modeled with 1D elements like CBEAM, CBAR, or CBUSH only can be used
