snappyHexMesh is generating cells with flat faces touching each other
2 Attachment(s)
I've recently run into problems where snappyHexMesh will generate polyhedra cells with a nonzero volume, but two faces directly on top of each other.
This results in problems because the Courant number will be extremely high in these cells, and adaptive time step methods will fail. This problem is not detected by checkMesh, since common quality measures like non-orthogonality or cell volume are unaffected. I think this issue needs to be considered in the detection of invalid cells during undo stage in snappyHexMesh. For reference, here's the checkMesh output: Code:
Overall domain bounding box (-2.10476e-08 1.47089e-05 1.07802e-05) (0.017315 0.0186159 0.0183828) |
