We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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.
