[blockMesh] ..neighbour cell face

hpon · July 16, 2010, 04:57

Hi,

When I run blockMesh I get the following message: "FOAM FATAL ERROR: face 0 in patch 4 does not have neighbour cell face: 4(8 9 15 14)". What does that mean? What is wrong with the patch?

I have attached the blockMeshDict file.

Hi,

I have the same problem.

Could you find a solution?

It tells you that none of the blocks (hex) that you have defined have block faces, which are defined as you have defined the boundary patch. I took a quick look in your blockMeshDict and none of your blocks actually contain all of the points on that boundary patch.

I have a similar issue with my mesh, with possible face ordering problems for the cyclic patch. Can anyone help some, blockMeshDict is attached.
