Derek Jing Guest Posts: n/a	Hi all, I am simulate fine powders flow out of a hopper using FLUENT 6 Eulerian multiphase model. I applied outflow B.C. along the bottom (nozzle), and applied pressure outlet B.C. along top surface. Now my problem is: even though the computed result shows that the free surface of particles drops, the mass flow rate along the bottom surface is always zero, which means no powders flow out. Can you give me some advice on this problem? Thank you in advance. Derek Jing
