Hello everyone,

I am currently working on a part whose topology needs to be optimized. Problem is that I have multiple loadcases. It's a T-form and it has bearings at two points. At the third point different loads are applied.

The other problem is, that modeling the bearings with coupling constraints doesn't give a realistic stress distribution which is highly important to me. A contact analysis gives way better results. So I need nonlinear analyses. But loadcases in Abaqus can only be modeled with a linear perturbation step where nonlinearity is not supported.

Is there a way in Tosca structure to implement different input files (one for each loadcase) to get an optimized structure for all loadcases considering rigid bodies in contact?

Help is highly appreciated. Thanks!
