Hi, I'm new to this forum, and I have unusual problem.
Results of modal analysis in the same model, I only changed the number of modes.
How is this even possible?

Indeed it's not normal.
Could you share your model

When I close and reopen model, it's fine, same result for 10, and 30 modes.
Strange, but OK.
But, I'm new in RSA, and have a lot of questions. 🙂
First is about parameters of foundation elasticity. What's the best solution for concrete foundation plate in RSA?
- define Kz, Kx, Ky
- define Kz and elastic support (Ux, Uy fixed) on plate edges
- define Kz and set a rigid suport (Ux, Uy fixed) on corners
- some other solution
