nrd13 is on a distinguished road
Hi there,

I want to make a 2D axisymetric model for indenter simulation. There is a roundness of 50 nm on the tip of inderter. The problem is probably there is not enough contact points between two body. Mesh is fine enough to resolve enough to indent depth but at the very beginning of solution solver gives a warning for abrupt change on contact status and then somehow it doesn't converge on solution.

Is there any solution to converge this simulation?
