Hello all, Here is part of my particle summary from an unsteady DPM (this was at a single time step and I didn't include elasped time here):

[Fate]-------------[Number]-------[Injection]----------[Index]

Incomplete--------1560-----------(blank)---------Min=0 Max =17

Escaped Zone 5-----2------------injection 0------Min=0 Max =21

Trapped Zone 14----27----------injection 1-------Min=0 Max=13

There is no information about injection for the incompleted particles. How can I know how many particles from injection 1 and how many of the injection 0 are incompleted? (They are not the same size.) And what's the index represent?

Thank you so much for your helps, OP

Which software are you using? It sounds like Fluent - there's a dedicated forum for Fluent.

Yes, I am using Fluent. And I've just learned that Fluent cannot provide information about the injection or ID of incomplete particles in unsteady system. In such case, it only reports the total number in the domain. And the index represents the indices of the injection and injection name with min and max elapsed time.
