Someone can help me?

Hi,

This means that the number of divisions that you have specified for an edge (in this case the edge connecting vertices 4 & 7) are different in different blocks.

Note that the block numbering in blockMesh/OpenFOAM starts from 0 and not 1.

So, in the two blocks that have you have defined that have the edge made up by vertices 4 & 7, one has 10 divisions and the other has 20 divisions.

Correct that to be consistent and that problem will be solved.

Cheers,
Antimony

Thank you very much, yeah the divisions are different.. Thanks again.
