    Hello Mr Rahul.

     

    Actually my analysis type is linear static analysis and my loading is cyclic loading because my model is automotive wheel rim.

    for this i am unable to find no of cycle vs load peak value (.cvs file) ,which is needed in FATDATA card image.

    For more detailed i am sharing to you tutorial .cvs data file,

     

    Please let me know how can i create .cvs file for my model. i am waiting for your valuable reply,

     

    Regards
