Hi Foamers
I maked a BlockMesh with 3 blocks-hex, but when I make the checkMesh, this is tne message:
Checking topology...
Boundary definition OK.
***Total number of faces on empty patches is not divisible by the number of cells in the mesh. Hence this mesh is not 1D or 2D.
Cell to face addressing OK.
Point usage OK.
Upper triangular ordering OK.
Face vertices OK.
Number of regions: 1 (OK).
......
***Number of edges not aligned with or perpendicular to non-empty directions: 117036
<<Writing 150853 points on non-aligned edges to set nonAlignedEdges

Attached my BlockMesh, please can you help me, i dont get a solution, i cant find the error .

I forgot add in blockmesh the next:
blocks
(
hex (0 1 4 3 9 10 13 12) (60 75 1) simpleGrading (0.025 0.012 1)//inletinferior

change "type empty" to something else like a wall

Default The mesh has multiple regions which are not connected by any face.
