Fluent DPM deleting particles during iteration
 

I am new to modeling discrete particles using Fluent and am running into a problem. When I inject particles at an independent timestep from the main solver timestep, the status window says that the particles are deleted when the solver advances to the next timestep.

Something like this:

1. Inject particles
2. Delete particles
3. Advance to next timestep
4. Perform specified iterations per timestep (main solver)
5. Repeat...
