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.

I would suggest to use automesh, accuracy 1 for testing, with 16 layers PML should be ok.  The goal is to reduce PML reflection, and resolve diverging issue.

do not use uniform mesh.
