To run a frequency analysis after a non linear large displacement analysis.

Hi everyone,

This is my first post on this forum.

I would like to know if it is possible to run a non linear static analysis on a structure I have and THEN running a modal analysis on the resulting deformed structure.

I cannot impose my loads directly in the frequency analysis loadcase because displacements are quite large and various non compenetration contacts must be taken into account.

Is there a way to do this?

Thank you in advance for your attention.


Best Regards
