Hi everyone.
I don't really understand where in my mesh there is no consistency. I get this error message when I try to run blockMesh for this mesh region: Inconsistent number of faces between block pair 4 and 6. Here is my blockMeshDict file: Code:

Hi,
Basically on the line connecting vertices 30 and 33 in block 4 you have 24 cells, while on block 6 you have 26 cells. Hence you have the error message. Cheers, Antimony P.S. You will have a similar issue with blocks 6 and 7 that you would need to correct for as well |
