Ok, it's very clear now. I have already made a big step forward. Now I'll have to work on it and to cope with convergence difficulties. It'll take a little time I guess, but I won't give up.
Thank you.
Thanks Denial!
It sounds great and I'm going to try to follow your advice, but I still have a question about normal contact elements between two surfaces: since the two surfaces are supposed to be in a situation of initial contact, shall I interface them with zero-lenght normal contact elements...
