How to constrain body to be solved as static problem

Using SimScale Solid Mechanics / FEA

hi
I am trying to model a part that is sliding on a floor that is subjected to force as shown in the image, but usually, I get an error: residual can not be achieved for MUMPS solver. I am using high-density polyethylene, I guess that the problem is that the body is unconstrained or the large displacement of HPDE

Hi, and thanks for using the forum!

The residual error that you mention is related to the mesh quality. If you do not want to refine the mesh much more, then you can increase the “Linear system relative residual” under Numerics, to a bigger value, say of 5e-4.

thanks for your reply

I tried to increase the residual and refine the mesh, but I was getting the same issue. I have done a few trials
