Hello Everyone,

i am trying to mesh a simple geometry with blockMesh. Now i want to refine some regions with simpleGrading, but it only works with 1 in z-Direction. I put everywhere the same number of cells but (15 1 x>1) etc. is not working.

--> FOAM FATAL ERROR:
Inconsistent point locations between block pair 1 and 2
probably due to inconsistent grading.

(2 in z-Direction for hex I - V)

When i am putting in first the z-Lines there is no Problem, but then blockMesh will not grade the mesh.

CheckMesh only failed the check about the aspectRatios which should be irrelevant.

Here is my blockMesh dict
