Frictionless contact between two steel member

[simon291]

Hi everyone,

I am trying to simulate the contact of two steel beams. The interface is frictionless. The pressure is applied on the top of the one beam. It seems there is something wrong with my model. Can anyone help me check the setting?

PS: I can run the case if I tie two members together. I just want to try the contact condition.

Attached is the inp file.

Thanks a lot.

Simon
