I need to look at a single particle in a cylinder that is rotating - it's the inspection process for contaminated syringes.

I can't seem to find any guides on particle modelling that don't use an inlet.

I've tried doing it myself but nothing seems to be visible.

Has anyone done something similar?

Thanks a lot,

Hi Greg,
You need to provide a injection point for your particle. This'll be a point location where your particle is introduced. This shouldn't require a fluid "inlet" in the domain.

Also note that you need to run your simulation in transient mode, as their are no complete trajectories from an in to an outlet. And, as far as I know at least, you won't easily 'see' the particle track, FLUENT itself only visualizes the instantaneous position of the particle. To see the history, you can export an xml file with the trajectories (visualizable with CFD post), or export the trajectories otherwise, using an UDF or so.
