non linear assembly

[vinsce]

Hi !

I've some problems with my assembly...
I use 3 kinds of materials : PA6 for the 2 top volumes , an elastomer HNBR for the volume above them and finally steel for the bottom volume. I apply an effort on the top surfaces linearly (6000N) and a constant pressure (4MPa). I have represented only one quarter of the structure.

Problems :
- I don't know if the non linear material models are suitable.
- How can I make the model converge ?
- etc...

I would be really gratefull if someone is able to give me some advice.

Find attached my program and the solidworks file imported in my ansys program.
