"WebDomain has one inlet, one outlet, and a body limited by two heated plates. At the inlet the liquid enters the domain, is heated, partially evaporates and leaves the domain via outlet. The problem is that the mass is not conserved. There is approximately 6x larger mass flow of the liquid/vapor mixture at the outlet that at the inlet. " - Openfoam mass flow inlet
