Contact Problem (For Johannes)

Hy Johannes,
I see your file, Isee the operation that you have made on salome, really I don't know so well all the capabilities of Salomè but Ithink taht you have done the same thinks taht I have done in Hypermesh to define wath I need to solve a simple contact problem.
In particular I define a "skin" of quad4 element on the 3D element of contact zone without detach it to Hexa mesh.
The contact zone is define considering quad4 element defined on to contact surface.
So I don't understand why my example don't run.
I attached it, can you see it and solve and explane me why don't run.
Waiting for an answer I send you my best regards.

Jacopo

P.S.:I try to contact also www.code-aster.org but the web site is blocked, so I send the problem also to www.code-aster.de

I'm just curious, how does this software work out for you guys? Do you get accurate results?

Thanks!

Hello, I just start to study the SW and try to testing contact and other capabilities, when I have some good result I put the model on Forum.

Ciao
