Hi to All!

I've created a mesh of a simple channel with snappyHexMesh (in parallel).
In principle meshing with SHM worked fine, simulation ran successfully.
Primarily the model had these boundary regions:
inlet, outlet : patch
wallLeft, wallRight, top, bottom: wall

Next I've changed the boundaries of LeftWall and RightWall to cyclic in blockMeshDict and I've adapted the 0/* files accordingly.




log-file 'log.snappyHexMesh_par' discloses this error:

Could anybody point out the problem?

Thanks!
