Reversed flow at the outlet
 
Dear all,

I have a multiphase system with water, magnetic and non-magnetic particles. the mixture flows down by gravity between two grooved magnetic plates. I have specified velocity inlet at the inlet boundary and outflow or pressure outlet at the outlet boundary. The pressure at the outlet is taken as 0 gauge pressure. although initially the simulation results are okay after sometime I get reversed flow and the flow of solids as well as water in the downward direction stops. Could anybody help in fixing the right boundary conditions.
thanx
