The difference between each other is clear, I suppose that it influences in the body deformation. My issue is analyse the contact between the edges, so the body's deformation will not be analysed. Because this, I was using Rigid Moment. But the warning is "One or more MPC contact regions or remote boundary conditions may have conflicts with other applied boundary conditions...."
I don't agree with the warning, but despite this, I tried with the deformable moment, only to see the results, and the warning changed to "One or more object is using a deformable behaviour but is applied to a collinear set of nodes. This is not recommended an can cause solver difficulties..."
So which them is correct, rigid or deformable?I think thaht is rigid, but and the warning?
Another result that I am not understanding why do not have compressive stress in the point that stay in contact after the load is applied.
The picture comparing both of them is below:
If anybody can help me, I will be greatful, I am doing my master thesis about steel bolted connections, so it involves a lot of contact problems.
Thank you very much!
