Ran a test case with two parcels falling and rebouncing against a wall and each other. I'm working on the parcels splitting when colliding. They bounce...

Have you tried setting the restitution coefficient (mu) to zero? I'm running the DPMFoam test case now and so far no parcels have either escaped or got stuck on any wall. The...

Thats the way i would have set up my BC.'s for total reflection. I'll be looking into DPMFoam myself for a few weeks for work. So hopefully I can come with more...

Wall instead of inlet sounds resonable to stay true too physics. How have you defined your localInteractionCoeffs? I think total reflection would be as the example usages is defined below. ...

Turbulence model? Transient/ steady-state flow? and so on If there were no energy loss wouldn't the particle be in total vacuum?...

Hi, With such grid size the particle drag can't be solved by the flow. If you would solve the drag with N-S the mesh size would be almost infinte. Thus my ideé is that it solves the particle...
