Hello, I'm trying to simulate with an axial-symmetry geometry. For this reason, in blockMeshDict, I've to specify an empty boundary "axis".
Then I've to create a baffles with createBaffles -overwrite command,

Create time

Create mesh for time = 0

Reading baffle criteria from createBafflesDict

Not converting faces on non-coupled patches.

Created zone baffleFaces at index 1 with 5 faces
Converted 5 faces into boundary faces in patches
2
(
baffleFaces_master
baffleFaces_slave
)


--> FOAM Warning :
From function int main(int, char**)
in file createBaffles.C at line 827
Setting field on boundary faces to zero.
You might have to edit these fields.

Removing zero-sized patches:
axis type empty at position 5

Writing mesh to 0
End

The problem is that this command deletes the empty boundary "axis". Is there any way to avoid this?
