Hello

Please try to comment the 'patches' section of your blockMeshDict file.

Then run blockMesh.

If it turns out ok, then add the first patch, 'inlet' in your case.

Repeat the same procedure step by step until you find where the problem is. By looking at the error message, I would think that the problem resides in the patch 'fixedWalls'.

Good luck!
