When I try to make a mesh with blockMesh; the vertices are ok.
But I can not do a refinement I like; I get the error inconsistent point locations between block pair 0 and 2.

When I put in the old settings for the refinement and try to make the boundaries, everytime I get the error that there are no neighbour cells or patches for certain patches.

I put in the picture and blockMesh file.

Depending on your vertex ordering each block gets a local coordinate system (see figure 5.5). I'm guessing if you draw the local coordinate systems in your case, you will have anti-parallel vectors in some directions.

Ok. I looked at the consistancy of all the directions and local coordinates.
I also learned that for the different regions at the top, I had to make different regions at the bottom as well, instead of 1 bottom patch.

Now it works, I attached the file
