How to fix this problem?

Hi @jmenear,

Thanks for posting your question. Here you have the solution: Divergence in Simulation: How to Tell When and Where? | SimScale


Now what should be done from this point?

In this case, two main workflows are possible:

  • CAD clean-up around the problematic region
  • Improving the mesh settings (for example, by applying additional local refinement, or improving the small feature suppression configuration)
