We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

Does convergence depends upon unit system?

      Maybe, Mechanical uses automated technique to treat successfully a vast variety of the nonlinear contact problems. The different numerical criteria and tolerance values can be used during solution for different units. The latter can cause slightly different solution behavior which can sometimes result in lost convergence for such extreme unstable nonlinear problem with large deflection during contact as presented. Mechanical output contains warning messages with the reasons for that and suggested methods to improve convergence.
