surajkvs is on a distinguished road
I want to implement Partial Slip condition on the walls for particle as in MPPICFoam as in Eulerian Eulerian solver we can give boundary condition as JohnsonJacksonParticleSlip which gives partial slip of partcle when it collide with the wall.
...................................
walls
{
type JohnsonJacksonParticleSlip;
specularityCoefficient 0.0001;
value $internalField;
}
.................................................. ................

Well but in lagrangian case we define patchInteractionModel in which we define value of Elasticity coefficient(e) and Restitution coefficient(mu) and Interaction type name- stick, escape ,rebound but is it possible to define partial slip condition for solids in MPPICFoam or DPMFoam.

please suggest if any body have idea.
