Hi to all.

I'm trying to make a simple cylinder but I get the following error:

--> FOAM FATAL ERROR:
Inconsistent number of faces between block pair 1 and 4

From function blockMesh::calcMergeInfo()
in file blockMesh/blockMeshMerge.C at line 217.

I read that this error occurs when there is difference number of cells between blocks. But I have the same number of cells for the blocks:

convertToMeters 0.001;

Someone can help me? and tell me which is the error.
Thanks in advantage

Hi,

Your block 1 is defined as:

hex (1 5 4 0 9 13 12 8) (100 50 50) simpleGrading (1 1 1)

This means that for the edge connecting vertices 0 and 1, there are 50 divisions.

However, in your block 4, defined as:

hex (3 2 1 0 11 10 9 8) (100 50 50) simpleGrading (1 1 1)

There are 100 divisions for the edge connecting vertices 0 and 1.

Consequently you have the problem of inconsistent number of faces between the two blocks...

Cheers,
Antimony

It's already working.

Thank you very much for your help Antimony.
