I think that conversation is about how to design clinching joint.

I already have a punch and die and I want to make a full simulation as on the first post is showed.

The problem which I have is that I can't make that "interlock" between the parts. 

Do you know if it is a problem with mesh sizing or some connection problems? 

Or simply I have to use other simulation that "statit structural" like LS-dyna or explit dynamics?

Of course I try to do that with "large deflection" etc. 

It is hard to try all options because all calculations take time.
