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?

[pnvk95]

Yes. Transient problem with unsteady particle tracking.

You may need to change dpm iteration interval.
