[FAQ]

When we have a moving zone in contact with a stationary zone we create a non-conformal mesh interface connecting a set of interfaces belonging to either zone. An interface has no particle boundary condition assigned to it and will let particles pass over it. If you want the fluid to be able to pass the interface but filter and keep the particles in one of the zones you can do this by putting the Discrete Particle Model Boundary Condition (DPM BC) on the interior zone that is automatically created when the mesh interface is created. The naming will help you find the interior zone that matches the mesh interface in question. Turn this interior zone into a porous jump by changing the boundary type. This will give access to a DPM BC. Then assign the DPM BC type to “reflect” if you want the particles to bounce back in the same way as if the interface was a wall. If the fluid should not be affected by the porous jump you adjust the parameters to have zero resistance by setting the “Face Permeability” to a large number and both the “Thickness” and “Pressure-Jump Coefficient” to zero.
