Nonlinear contact and h-adaptive mesh

Question asked by Sindre Abrahamsen on Dec 7, 2017

I am simulating (no penetration) the flank pressure distribution between two gears. The results are very bad when I try the h-adaptive mesh:

The flanks are smooth so the pressure should also be smoothly distributed. This is as expected when I do the meshing myself:

What can I do to get the adaptive mesh to work?
