Hi all,
If I try to make a mesh from the blockMeshDict below, it throws the error "inconsistent point locations between block pair 1 and 2 probably due to inconsistent grading". Anyone who knows where the mistake could be?

I found the solution, OpenFOAM choked on the size of the domain, it worked when moving everything 517m to the left. New origin is point 4. There were also mistakes in the locations of the arcs. New working code is:

convertToMeters 1;
