Reply To: Calculation of a centrifugal pump in fluent

I'm using a mixture model. I need a mixture because... water comes immediately with gas.

I'm using incompressible gas.

No I don't use steady state. I use transient analysis.

I use the setting pressure at the inlet and mass flow at the outlet.

I managed to solve the problem using the SIMPLEC method, with great relaxation:

 

Only the pressure makes big leaps:

 

Otherwise everything was set.

I achieved a solution only in the first orders of the SIMPLEC method. What do you think about this?
