    Hi Srikanth,

     

    You can use CMSMETH (in load collector) case control card and specify the method to GUYAN in the same in OptiStruct. CMS stands for Component mode synthesis.

     

    Please refer to the topic 'Creating Superelements' on how to use CMSMETH card.

     

    Altair OptiStruct > User's Guide > NVH Analysis:

    Creating Superelements

     

     

    Please refer to CMSMETH for more information on CMS method.

    Please find out the cards necessary to perform this analysis in NX Nastran from Nastran Manuals etc and we can help you create these cards and preprocess in HyperMesh, this is the ideal procedure.
