Element with 5 faces and a needle face
 
3 Attachment(s)
Dear all,


I am trying to simulate a ducted fan just for practicing OpenFOAM. When meshing with snappyHexMesh, the systems dumps a cell which seems to have 5 faces and a needle face (due to the snap of the block mesh with the walls.stl file) and that's why I think my snappyHexMesh crashes. I have attached 2 screenshots of my geometry and the aforementioned cell and also the snappyHexMeshDict. I have tried to play with all the refinements but I didn't manage it to work properly.


Do you have any tip about where I should start looking to fix this issue?
