SnappyHexMesh for internal flows
Hi There!

I've a question about sHM.

My geom is a boxlike thing where I want to simulate the flow inside.

Now i made a blockMesh which is bigger than the geom and from there a snappyHexMesh. Unfortunatly sHM is not deleting the blockMeshPatches which have correctly 0 faces. It's not really a Problem but more to define in the boundary files.

Has anyone any advice how to get rid of the "empty" patches?

Thanks n greets

Hi Jim,

have you find any solution since then ? Are you still encountering difficulties with meshing the interior of surfaces ?

Just delete the entries in constant/polyMesh/boundary. Remember to decrease the number of patches specified at top in the same file.
