No/partial/full-slip BCs in pure DEM?

Hey MFIX community, I want to make sure I understand the mathematical implementation of the no-slip, partial-slip and full-slip boundary conditions in a pure DEM framework (no fluid) with a linear spring-dashpot contact model. I’ve noticed that the friction coefficient for particle-particle and particle-wall interactions is input in the “Solids” dialog (see below) as a property of the particles, while the BC dialog has options for “no-slip”, “partial-slip”, and “full-slip” at a wall boundary. …
