well posed boundary conditions for HVAC grilles

(OP)
Hi everybody,

We are working in a system with an HVAC duct with two outlets, something like in this sketch

Our consultancy uses a model applying the following BC:
set the inlet flow fixed, and P=0 at the front surface of the plate holes and slots (almost aligned with the duct wall).

I don´t feel too comfortable setting P=0 at the exact holes of the perforated plate or at the slots, is that a good practice?
I have been seeing that BC are better imposed at zones with "steady" flux, and the jets from the diffusers don´t seem to me like a good option.

Regards and thanks for reading
