Volumetric flow rate of a naturally ventilated room
I am studying in a room that is naturally ventilated. A small room inside the air domain. I just want to find out about the volumetric flow rate in the room only. But I'm getting the full air domain rate right now. Since I'm new to this field, someone could guide me, please, how I could get that value. In geometry, I combine the air domain with the room fluid region.
