I am modifying the interCondensatingEvaporizingFoam by adding different phase change models. I met a very weird thing. When I run a case using the modified solver, in the first 0.3s, the flow parameters, including temperature, velocity, pressure, and phase volume fraction develop well. But suddenly, the pressure field becomes completely wrong, while other parameters, including temperature, velocity, and phase volume fraction still develop well. It seems that the pressure field does not correspond to other flow parameters after the pressure field becomes wrong.

It has puzzled me for a while. Does anyone give me a hint of where the possible reasons are from?
