particle deposition
 

I 'd like to set 3 particle injections(e.g,30particles for each injections) for different diameter of 20um,1um,0.01um and compare the deposition velocity. i am using the unsteady tracking, the problem is when i starting the iteration, Fluent mix the 3 injections together,that is ,it will show on the console windows: number tracked=90,trapped=15,escaped 75,sth like this,so i can't get the trapped number of particles for each diameter.can you help me ?thanks
