Hello everyone,

I am simulating the interaction of particles of polypropylene injected to water tank. I have already converged the continuous flow with VOF for the interaction of air-water inside the tank and now I want to introduce the particles to my model with DPM.

It is assumed that it doesn't affect the continuous flow (1-way coupled) and also it is tracked by unsteady tracking. My flow time now is at 3.22 sec so I put as start time 3.23 sec and stop time 3.3. However, when it reaches 3.23 no particle is tracked.

Mass flow rate is at : 0.1 kg/s. X-velocity-> 0.2 m/s Y-Velocity--> -0.5m/s and parcel containing 4000 particles.

Does someone know why DPM is practically not working?
