Hi Foamers,
I refer to the forum: --> FOAM FATAL ERROR: Trying to specify a boundary face but i don understand which is the solution and what the solution is about...im too novice in OpenFoam. So I succeed the blockMeshDict from my successful case of 7blocks together making an 'I' shape, unfortunately this time to make a 27 blocks i faced the error: Code:
--> FOAM FATAL ERROR: Trying to specify a boundary face 4(21 37 42 26) on the face on cell 13 which is either an internal face or already belongs to some other patch. This is face 0 of patch 0 named HeatedWalls. Code:

The problem tells you that the boundary "HeatedWalls" is inside of your mesh, and not an actual boundary.
If your goal is to create a thin wall inside of your mesh, look into using baffles (createBaffleDict) |
