ANSYS FLUENT:

I am currently trying to model a system in which a two phase (water and air[ Volume fraction 20%]) passes through an impeller.

-Mixture Model
-K-epsilon Turbulence Model
-Rotating reference plane of impeller location at 100 rad /sec
-Inlet velocity, water=0.6 m/s and air 0.5 m/s

The problem that I am having however is that the solution is that the AMG is diverging.

Any tips on creating a model for this system would be very much appreciated as I am no expert at CFD.

Thanks.
