Boundary conditions for the modal analysis of a rocket

      Hello,

      I am trying to do modal analysis of a rocket just after the take off condition. I want to calculate mode shapes and relative stress at the large deformation areas. What boundary conditions should I take for this analysis? I have only given payload as point mass in the payload attachment frame. Can anyone please tell me what else boundary conditions should I take?

      Please don’t post the same question in multiple channels.  I have answered this question in this post: https://forum.ansys.com/forums/topic/boundary-conditions-for-the-modal-analysis-of-a-rocket/
