Hi guys, I tried to make two hollow beam for geometry to run in modal analysis but when I run this , get result only one part is moving . And I confused why this hapen

Hi

Seems something is not connected there – see if the mesh is compatible or if the contacts are active etc. (Or somethng with strange material prop.).

Or if no contact at the far edge where max. disp. is seen in that mode, perhaps then it is just a natural mode of that inner structure, which seems connected on the left but free on the right hand side so it behaves a bit like a cantilever in 1st bending mode.

Make sure to think through the restrains and all connections etc.

All the best

Erik
