question on granular flow simulation
 

Hi all,

I ever used FLUENT 6.0 to simulate granular flow, but I failed. Now I try to turn to CFX. My question is:

(1) which version shall I choose: CFX 4.x or 5.x?

(2) How CFX model the boundary condition between particle and wall? What kind of USER subroutine can I use?

Thank you very much.
