Hello, Rob, thanks for your reply and thanks for explaining this phenomenon with phases, I'm using 0.005 step size. I just came back from uni, where PhD controlled my model and gave me an answer. In my model doesn't work the law of conservation of mass because the vapor in the cube is isolated and pressure is settled to a constant value. Water has way bigger density, during condensation pressure in the system rapidly decreases, leading to error. The model needs a pressure-inlet so it can maintain the pressure. I explained this to someone who will have the same problem and will be looking for a solution.

I tried to set one and now my calculation is running for more than an hour, I hope the result will be close to reality.
