DPM BC "Reflect" for Pressure Outlet
 

Hi I am simulating a wave tank where one side is a velocity inlet and other side is a pressure outlet. But after the DPM injection I set both the BC for the inlet and outlet as "Reflect" in the DPM tab in the BC conditions of each. I wanted to keep the limited particles inside the system though the water flow is like a channel. I'm not sure if it's working.

Does DPM particles leave the system through outlets even though the BC of the outlets are set as "Reflect/Trap"?

Thanks a lot in advance
