Hello, Prashanth,
I ran a case that used an air conditioner and an air purifier to dilute the particles in the room. 2400 particles are uniformly distributed in the room initially, and the initial concentration showed good agreement with my calculation. However, after the simulation run, the concentrations at different time steps are the same as the initial concentration. I expected that the particle concentration could decrease as time passed, but it didn't. Did the escape and trap particle also take into account in my UDF? I don't know how to fix it right now.
