Thanks for your suggestions, Rob! I’ve changed the particle residence time into the particle diameter, and the particles showed up in my model. However, after I ran my simulation (Numbers of timestep=5000, timestep size=0.05), the particles didn’t move. I already give a inlet air velocity with 2.5 m/s, and I don’t know why the particles didn’t move with flow (My assumption is one-way coupling). The following picture is the locations of 160 parcels, and the location is fixed no matter the time pass.
