snappyHexMesh after extrudeMesh / Creating background mesh with extrudeMesh
i want to run a procedure like:
2.) snappyHexMesh -overwrite
4.) snappyHexMesh -overwrite
In other words, the background mesh for the second snappyHexMesh-procedure should be created with extrudeMesh. My problem is, that the steps 1-3 works fine, but when i run SHM again (Step 4), i get an error-message:
It's quite an old post, have you figured out the solution?
My bet would be:
a. delete all the cell sets, face sets, etc. from the polyMesh directory
b. remove all the files created by snappy in the 0 directory
c. check that all your boundaries are defined properly after the extrude mesh procedure; if not then use topoSet and/or createPatch -overwrite to create new patches or remove those with 0 faces in them
thank you very much for your reply, unfortunately my problem is not solved yet.
Meanwhile, i found out that some files in the polyMesh-directory have to be deleted (as you already mentioned in your post).
Right now, i think my that there is no solution for my desired procedure. This is because snappyHexMesh requires a background mesh which consists (only) of hexahedral elements. But an arbitrary shaped geometry will lead also to tetrahedral- / layer- / other elements, therefore (in my opinion), snappyHexMesh can only be used one time.
Well too bad it didn't work, would have been a nice tool.
Thanks for sharing your conclusions anyway!
