Hi
I study the natural ventilation in house and I need to find the volume flow rate through openings ,I tried to use surface Integral for the velocity on the interface surface between the outside air and the room air ,but the problem that the results show unrealistic high values for the flow rate. I checked the domain, the physics of the problem, etc. However could not find anything wrong. So I hope you can help me in this issue ?

With best regards

do you have experimental data to compare with.
check your turbulent model and the grid system.
