Hi!
Im simulating 2D geometry of a centrifugal pump and Ive specified pressure inlet(1.02 atma.) and pressure outlet(3.79 atma.) as boundary conditions. But the simulation doesn't converge and I'm getting very high mass flow rates in the report----> flux panel. The expected values is 1.833 kg/s and the obtained value is 207 kg/s. Ive looked into the FLUENT manual but I cant pinpoint the reason. Im using sliding mesh with coinciding interfaces separating the moving domain with the bulk. Any comments?
