Hi, i checked the mesh of my recent simulation and saw that the first few layers of my prism layer are all underdetermined. The first ~5 layers are affected. Is there a way to handle this numerically? I suppose i need a +y of ~1 what the mesh achieves, however results at the wall are not physically reliable.


Thanks in andvance!
