Wall Boundary Condition for Multiphase System

Zahoor · July 19, 2016, 12:04

Hi Everyone.
i am dealing granular particles in a conveyor. now problem i am facing in defining wall boundary condition. as i have to use no slip for air and partial slip for granular. but the problem is that when i open wall settings it doesn't show separate options for air and solid particles mean either it can be no slip for all phases or free slip for all phases. how can i apply different B.C's for multiple phases.
Thanks

Is there a "Fluid Dependent" option under Mass and Momentum ?

no in wall setting it shows three options
1- No Slip
2- Free Slip
3- Specified Shear.
