I meet a problem in the fluent simulation.my model is simle ,it is water falling from a 2-dimension verticle ,the water inlet is setting as a constant velocity,the beside boundary sets the no slip wall condition, the verticle wall sets the no slip wall condition too.The boudary contray to the wall and the outlet sets as the pressure outlet condition (it's Gauge pressure=0Pa,Reverse flow fraction: phase 2=0),but when I simulate,it always give the signs "there are reserve flow in 2189 faces in the pressure outlet 6" ,how can I solve it .
