Only for a hex are directions

Only for a hex are directions (normal, tan1, tan2) defined. For polyhedral cells it reverts to geometric cutting (with a plane through the cell centre) which will probably fail on your curved mesh.

Your patch cylinderWall has no

Your patch cylinderWall has normal in x and y direction so the undefined direction is the z so my local coordinate system can be:

Does it work with a 'square' case, e.g. the cavity tutorial? Using patch 'movingWall' and tan1=(1 0 0) and tan2=(0 0 1)?

you'll need to use - patchL

you'll need to use

- patchLocalCoeffs
- useHexTopology true
- geometricCut false

And switch on the debug switch for hexCellLooper.

Is your mesh pure hex?

refineMesh can refine in 1,2 or 3 directions in one go. These directions are given the symbolic names 'tan1', 'tan2', 'normal'
