[blockMesh] Error -blockMesh

Hello Everyone ,

I'm facing this error
"face 3 in patch 2 does not have neighbour cell face: 4 (20 18 30 33)"

My blockMeshDict is attached .

Before adding boundary, all vertices and blocks were checked and I could view it in Paraview . I'm sure there is problem in boundary but where ?

Could somebody please help me ?

Regards
Maral

Hi,

If you look at the blocks you have defined, there is no block where the vertices 20, 18, 30 and 33 all exist in the same block.

As a result, there is no such face that blockMesh can use when it is creating the boundary patch.

18 and 30 appear with 19 and 31, while 20 and 33 appear with 22 and 37 & 16 and 26.

Hope this helps.

Cheers,
Antimony
