We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

OK, you're most of the way there. Having switched the interior zone to wall you now have a wall and wall:shadow - ie an internal wall. In the TUI (Console) use 

/mesh/modify-zones/slit-face-zone

To change the wall from an internal type to external. You can then set those as interface, and from there set the non-conformal interface pairings.  If you build the models in the Ansys tools this is a little easier as we can do most of this before going into Fluent.
