Hey,
I am trying to create a mesh around a cylinder (2D) and I'm always getting an error for my patches-definition. The first one is accepted and for the second one I get the message:
--> FOAM FATAL ERROR:
face 1 in patch 0 does not have neighbour cell face: 4(5 37 43 11)
although it's generated exactly in the same way.
Could anyone tell me what I'm doing wrong please?
I know that this face really doesn't have a neighbour as it is an outside face. But the one before did work.
The mesh has got 32 vertices and on the left side they are numbered 0/32 5/37 11/43 18/50 23/55.
The error occurs in the lines:

(11 43 50 18)

)
