Particle sticking model in MPPICFoam solver
 

Good morning,

I am currently trying to model particle deposition, rebound and resuspension on a tilted surface facing a mixture of wind and particles. In my case, i am using the MPPICFoam solver (similar case to Cyclone in Tutorial), and I would like to know if there is a way where i can change the rugosity of the surface so they dont slide and stick. How is that possible ? Or a way to define a critical velocity below which all particles are stuck on the surface.

Thank you for your help !
