Hello all,

I got a strange behaviour with snappyHexMesh. I have defined two STL-geometries. See Bild4 bild4.gif . Here the blue shape if the main shape. The gray inside should be used as a zone. As shown with the orange cells, this works fine except some cells, which are located in the nowhere (bild3 bild3.gif ) in the middle of the zone shape. With other words: These cells belong to the internal zone, but where not inside the "zone"-stl. I have tried different background meshes, different refinement level and blocks and so on. I have no idea, why snappyHexMesh does the zones like this. There is no logic. I attach two additional pics.

Can someone help me out?

Christoph

I just have done the internal zones with new a CAD-model and exported this to STL. Now everything works fine.

BUT I do not know why. The old STL passed every check and was closed.
