Reply To: Non-conformal Mesh: Boundarie is automaticly set to wall instead of internal

If you're remeshing every time then a single body makes more sense, and that also eliminates the poly layers in the middle of the domain. 

I'd use a conformal mesh (share topology at geometry level) and then slit the interior to get a nonconformal mesh, the Frame to Mesh Motion will do that for you: I've been using the code a while so use the "old" command approach out of habit. You can then alter the AoA using the flow solver to cheat.
