Default granular flow in the packed bed

Hello! I try to model granular flow in the packed bed. I use Eulerian multiphase regime, set parameters the same as for fluidized bed (fluent tutorial), also I set frictional viscosity and frictional angle for Shaeffer equation. I have never found good solution. What is the matter? Whether it was possible to somebody to solve this problem correctly?

rather vague question. Have you remembered gravity? Dr. Flow Squad
