I have made some progress with that. I am able to work patch-wise now due to better Hypermesh import (thanks) and this helps a lot. So far I found two patches that makes snappyhexmesh hanging if...

Eugene, thanks for this hin

Eugene,

thanks for this hint. I was aware of that and I am definitely not running out of memory nor swapping.

Refiner is obviously hanging at certain parts of the surface. How can I find...

I see I can get closer to the problematic areas by fitting refinement regions. Some regions of my geometry make the mesher hang up if going finer than level 4, others when going finer than level 5....

SnappyhexMesh and Symmetryplane

Hi Group,

I have problems with a case with symmetry in snappyHexMesh. My geometry has free edges at the symmetry (y=0). These edges are exactly at the border of the initial hex-mesh created by...
