Hello,

I am trying to simulate nonlinear analysis with thin sheet metal parts. Between them i have set no penetration contact with node to node type. But during analysis shell elements still penetrates each other. I tryed to create smaller mesh, but it doesnt work. This contact works fine with surface to surface type, but it's makes much more time to calculate model. Can i ask you, whats wrong with this contact set? Sorry for my bad english. Thanks
