Hello everyone!
I'm new to FOAM and I'm setting up a case for a pressure-driven flow in a channel with a buffer zone.

My blockMeshDict looks as follows:

When I use the blockMesh command, I get an error as follows:
//face 0 in patch 2 does not have neighbour cell face: 4(14 10 13 15)

I tried running blockMesh with only one block at a time and still got the same error for different faces.

I've tried solutions found online but with no success


Please help. Thanks in advance
