Console reporting for DPM

      Hello


      My simulation is running slowly because it is reporting the DPM data in the console after every time-step (part of report attached below). I want it to report every 1000 time-steps instead. How can I make sure the console doesn't report so often?

      Are you using unsteady flow with unsteady particle tracking?

      Yes. Transient problem with unsteady particle tracking.

      You may need to change dpm iteration interval.
