I have a room with an inlet for fresh air and additional a person in the room who is breathing. Now if I compile and load the Age of air UDF with DEFINE_DIFFUSITY and DEFINE_SOURCE the code is working but the code runs for both inlets. The fresh air inlet which I want the code running and the breath Inlet of the person in which I don´t want the Age of air in it. Is it possible to give one inlet the UDF scalar and an other Inlet not?

Best regards

You'd typically run the MAA UDF on a frozen flow field after running the model. So in that case change the mouth to a wall and then run MAA. The flow field is unchanged but the scalar won't see the second inlet.
