Airflow due to pressure differences
 

Hello!

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.

Hey,

Were you able to figure it out
