Hi everyone,
I'm trying t orun a multiphase simulation, with multiple inlets, some of which have very high mass flow values in them, resulting in a high Mach value. Since the case has multiple phases, and the wet steam model doesn't work in this particular case, I have to run a pressure-based solver.

The problem is that pressures and densities I'm getting at the inlets doesn't match at all with the results I'm supposed to get. I'm talking of getting a 3.5 kg/m3 density when I should have 48 (I supposed this is due to the error calculating the pressure field).

Mach numbers are in the order of (0.8, 1) locally at the inlets, so I assume that it might be a problem related to the solver.

Is there any way of solving these types of cases?

Thank u very much
Alex
