Negative volume in mesh due to contact

I am simulating a ball inside a valve that its motion is determined by a UDF.
When the ball gets close to the wall I get errors about negative volumes. I tried refining the mesh, decreasing the time step, improving Flow Courant Number and relaxation factors. Also, I added the contact detection specifying the boundaries but I still get the same error.
Do I need to compile a UDF for the contact detection?
If so, any advice or push in the right direction would be appreciated.
