Nonlinear Contact

Wow--3 exclamation points--what an exciting problem! And 4 question marks--what a puzzler.

So far we can surmise that the problem is about (no e) some nonlinear (with an a) phenomenon involving contact. But what is the question, pray tell? And what kind of contact: thermal, electrical, or bodily?

Hi Friend...

Maybe my problem is laughabli...

I tell my problem with a very easy sample...

for example I want move a Body upon ground that have about 1 cm distance from wall. when the body get the wall we have stress and strain in body and wall...

the velocity of body is a little; therefore we have not any impact in this process...

please explain for me the option of contacts between body and wall and ground and options of meshing COMPLETELY...
