Advanced boundary conditions

Hi everyone,

 

I have a question regarding the boundary conditions. Is it possible to define translational boundary conditions which only act in one direction? So for example only in the positive X-direction and not in the negative X-direction. So that these regions can only transfer compression and separates if put under tension. This means that the reaction force can only work in the direction of the object and not in the opposite direction. Is this somehow possible?

 

Regards, Mike

    It looks like a contact condition?

    Maybe CGAP element can describe that.

    I'm not sure about CGAP elements. But a CGAPG element should do the trick.
