I'm trying to simulate a compression test with a non-linear hyperelastic material. Everything is set correctly to my knowledge but it keeps on failing. I've added the mesh settings, the face and edges connectivity (shared topology), analysis settings, and two screenshots of the convergence failures in the pictures below.
Could someone please explain what I'm missing or what is wrong, I would really appreciate it!

See if the video in this discussion gets your model to converge.

It's been a while and I've tried many things that you've suggested via your link. However, I need to start with one of the first problems. I created a structure in SW and made it a shell model, next I've imported it into ANSYS. From here, I am able to define the thickness and the thickness mode however, for some reason it won't allow me to create one uniform structure. The structure is penetrated by the surfaces and does not look nice. How can I create a good looking and uniform model? I've attached some pictures to make it more clear.

Open the surface model in SpaceClaim. Perhaps the surfaces don't meet precisely at the same intersection point. On the Workbench tab, use the Share button. Increase the tolerance until all the edges are shared.
