andresbh is on a distinguished road
Hello all!

Is there a rule to use snappyhexmesh with cyclic boundary conditions? I have modeled a pack of spheres in Blender and tried based on the tutorial channel1395 to incorporate these into the flow.

Up to now I always get the next error end when applying snappyhexmesh.

Is there an option in the snappyhexmeshdict that could correct this?

Segmentation fault

I also simplified the test and only added one sphere, see attachment. I ran snappyhexmesh again but I had no success and got the same error.

Thanks for your help
