Baffle meshing problem with polyedral mesher
 
Hello!
I'm having this problem:
having a baffle floating in the same continua i define it as an interface and then go trough the volume mesh
when i initialise the run it tells me that the baffle interface is invalid because all the cells spans both sides of the interface:confused:. This happens only with the polyedral mesh (no problems found with a tethraedral volume mesh)

can someone help me? I cannot run it on tethraedral as the cell count is 5 times more.

Hey, I realise this post is already from long ago, but I am facing the same problem now and was wondering if you or someone else knows a solution to it now?

Warning message:
The following potential issues were identified while verifying initialized interfaces.
============================= Interface Initialization Warnings =============================
1. Interface [ interface1 ] has invalid topology.
33 cells span both sides of the interface.
================================================== =============================

EDIT: I found out that the definition of a baffle interface is not required when not modeling heat transfer. Removing the interface and simply defining the two sides of the baffle as adiabatic walls fixed the initialization issue.
