Hello Fellow foamers,


I'm being driven insane about what i think could be a bug.

vertices
(
    (16.25 0 0) //0
    (22.25 0 0) //1
    (21.446152422706632 2.9999999999999996 0) //2
    (16.25 0 100) //3
    (22.25 0 100) //4
    (21.446152422706632 2.9999999999999996 100) //5
    (16.25 6 0) //6
    (16.25 6 100) //7
);

blocks
(
  hex ( 0 1 2 0 3 4 5 3 ) (1 6 10) simpleGrading (1 1 1)
  hex ( 0 2 6 0 3 5 7 3 ) (1 12 10) simpleGrading (1 1 1)
);

The blockMesh file above gives me a

--> FOAM FATAL ERROR: 
Inconsistent number of faces between block pair 0 and 1

What am I doing wrong? I have a multitude of similar cases in my meshes that use the same construction time, and none of them have this error, except for this exact orientation of the triangles. changing the mesh nº of cells to the same value in both hexes fixes the problem, but i need this number of cells.


Thank you,

Hi,

AFAIK, you are having problems because you cannot specify two different number of divisions on the same edge. In the first block, you specify 6 while in the second you specify 12, which is not allowed and doesn't make sense.

You can duplicate vertices and in the duplicate edge, you can specify a different number of divisions.

Be warned though! You will need to see how to connect the duplicate entities. I don't know if mergePatchPairs would work.

Cheers,

Thank you for your reply,

I am aware of this limitation, but for both triangles the faces being joined together have only 1 mesh point. The 12 and 6 are for faces that are in no way connected.

Cheers,
