We’re putting the final touches on our new badges platform. Badge issuance remains temporarily paused, but all completions are being recorded and will be fulfilled once the platform is live. Thank you for your patience.

Correct re the coupling. 

If you want to see a change with more DPM mass you need to couple (interact) the particles with the flow. That way if there is sufficient particle momentum you'll see a change in the flow field and that will intern show a change in the particle trajectories. But... You may also find the particles slow/accelerate to the flow speed fairly quickly so the differences may be very small, potentially to the point of not being noticeable.Â
