I am having trouble in several models I run where contacts are involved. I am applying a contact between two surfaces and when the simulation is run the following error message appears:
No convergence could be reached. If you used manual timestepping try to decrease the timestep or use auto-timestepping. Otherwise check your settings again or contact our support team for problem specific help.
Is this due to the fact that one surface is given a much finer mesh than the the other when I use automatic tetrahedral meshing?
I have seen in some simulations such as Transient Thermal Analysis of a PCB that sections of one surface, the PCB in this, are defined as their own topological entity set.
How is this done? Are there several ways to resolve the issue I am having.
Thank you very much.
