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. 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.
