Ok sorry for the post, I figured out what my mistake is and corrected it.
I am a novice OpenFoam user and I ran into this problem which running blockMesh. Can someone explain to me why I am getting this error?

Creating block offsets
Creating merge list

--> FOAM FATAL ERROR:
Inconsistent point locations between block pair 0 and 2
probably due to inconsistent grading.

From function blockMesh::calcMergeInfo()
in file blockMesh/blockMeshMerge.C at line 294.

FOAM exiting


My blockMeshDict is as shown below
FoamFile

version 2.0;
format ascii;

object blockMeshDict;

Hi Ashwin,

the mesh grading between block 0 and 2, and between 1 and 3 doesn't fit.
The first block has a 0.1 grading in x-direction and the second has 10 in x-direction while they are connected in the x-z-plane.

Just choose the same value for the grading and it should work.

regards
Alex
