Hello CFD Community,

I am new to CFD. I am currently working on pollutant dispersion at urban street. I have created a 3*3 symmetric building grid. My target building is at the center of grid surrounded by other buildings (plain blocks with walls). My target building has windows on both windward and leeward side for cross ventilation. I used UDF to generate ABL profile. I created line source to account for roadway traffic emissions as pollutant inlet BC. My simulation ran successfully. I could see pollutant dispersion around the street.

I have few doubts -
1. Is there a way to visualize contour on the pollutant entry inside the room of my target building.
2. Do we need to define an UDS for passive scalar transport of concentration inside the room?
