I have two-phase flow in a domain. There is a phase change in the domain and I have turned on the thermal phase change model. If I monitor the mass flow rates at the inlet and outlet for the mixture they don't match!
Can someone explain this please. I have tried the mass flow rate of the individual phases as well, but the difference is huge!
My continuity residuals are of the order 10^-3.

Thank you.
Regards
HM.

Try lower convergence for Continuity and also VOF. Something 10^-4 or 10^-5 even.
