FUDM is on a distinguished road

I'm new at working with CFD software, so my knowledge is very limited.

I'm working on a simulation using CFD commercial program Flow-3D. My goal is to simulate the airflow between two adjacent rooms, through a small hole. The rooms would have a pressure difference between them of -50 Pa (de-pressurization), meaning one room would suck air from the other. The results will then be compared with a blower door test.

Can anyone give me some tips on how to perform this simulation, such as boundary conditions and other important parameters?

Thank you.
