Hello everybody,

I'm trying to simulate the airflow in and around a greenhouse for my thesis.
My problem is how to approach the windows. I have 3 different window opening positions. I created 3 separate solids, with the intention, in fluent, to be able to define which is a wall (the one I want to simulate) and which an interior (the other two).

When I go to Meshing it recognises a contact region between the two windows and afterwards in fluent I can't define them as an interior, so they will not interfere with the solution.
I also tried to merge the 2 faces between the windows but again no luck because the minimum angle isn't between 90-180.

Thanks in advance.
