Hello World.

I'm doing a rather complex mesh for channel flow using 36 blocks to get the appropriate mesh resultion at the walls.

The mesh despriction itself is working brilliant, but when I try to set the cyclic boundary conditions I'm getting this error:

face 1 area does not match neighbour 36 by 160% -- possible face ordering problem.
patch:INOUT my area:36 neighbour area:4 matching tolerance:0.001
Mesh face:61 vertices:4((0 2 0) (0 20 0) (0 20 2) (0 2 2))
Neighbour face:96 vertices:4((300 0 2) (300 2 2) (300 2 0) (300 0 0))
Rerun with cyclic debug flag set for more information.

Can you tell me what I should look at in my blockMeshDict concerning this error?
I'm not sure what is meant by the "possible face ordering problem".
