i am new in the use of fluent.
I need predict a h-q curve for a pump. My periodic mesh impeller was created on gambit.
I put on boundary conditions as follows.
Fluid: Water / rotation axis direction x=1 (because i put my rotation axis direction on x) / moving reference frame / rotacional velocity "3480" rpm
inlet: Mass-flow-inlet /mass flow rate: 0.323312 / supersonic/initial gauge pressure: 0 / direction specification: Normal to boundary/ reference frame: Absolute/ turbulence intensity: 5% /hydraulic diameter: 0.01896385
outlet: Gauge pressure: 791424.4 / backflow direction specification method boundary: Normal to baoundary/ turbulent intensity: 5%/ hydraulic diameter: 0.01345759 /target mass flow rate: 0.323312
i use first order discretization on flow / turbulent kinect energy / turbulence dissipation rate/
but doesn't converge the solution... what´s happening?
