Hello,

I have this annoying error. I made my blockmesh with huge attention. Still I have this issue. It says:

Inconsistent point locations between block pair 7 and 8 probably due to inconsistent grading. From function blockMesh::calcMergeInfo() in file blockMesh/blockMeshMerge.C at line 294.

Here is my blockmesh:

FoamFile
{
version 2.0;
format ascii;
class dictionary;
object blockMeshDict;
}
// * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * //

convertToMeters 1;

I found solution:
hex (18 19 27 26 22 23 31 30) (56 34 1) simpleGrading (1.1 0.90909 1) must be hex (18 19 27 26 22 23 31 30) (56 34 1) simpleGrading (1.1 1.1 1)
