How should I set the boundaries for a flow from one space to another space in a building.
here is the volume flow, a fixed data
So I will remove air from one room and take it to the other room.

Hi Mark. Assuming the rooms are connected? The easiest way is to apply a flow rate on one end (the inlet) and apply an outlet boundary condition on the other end to represent a return in the system. Easiest outlet BC is a Pressure = 0 on a surface.
If this doesn't make sense, either post an image here (if you can) or a "share" file (File>save>share file)
The drawing is a sectional view of the building, it is a building in a building. like a box in a box.(see Attachment)
the air inlet from the floor and the air outlet in the wall.
the model is made in revit and read into CFD 2012, I have two mass placed. 1 in the inner sanctuary building and 1 in the entire building. these two overlap each other.
I want to simulate air flow between these two. under the influence of solar radiation and temperature outside.
How should I set my boundaries. what happens to the two mass which overlap and are set to air.
I like to hear it,
In order to get air out of the building, I have a hole at the bottom, and holes made in each floor in the model. in this way, the air can leave the building.
but how do I set my boundaries for this, just the flow or by pressure and flow.
I let the model solve, but in the end it does not go feather. If do a 100 iterations it stops at 99 and if i
do 300 iterations if I stop it at 299.
what can this be?
