It fixed the problem. Thanks a lot!

Thanks for the quick response! I attached the simulation file.

I'm new to thermodynamics and process simulation, so this may be a very basic question. I made a material stream with the following mass fractions: - Ethanol: 0.05 - Water: 0.95. Then I ran "Pressure and Enthalpy (PH)" calculation with pressure = 101325 (Pa) and specific enthalpy = -1629.42912178436 (kJ/kg) using the Raoult's Law. But after the calculation the specific enthalpy value was modified to a different value 156.545 (kJ/kg). And if I entered the -1629.42912178436 (kJ/kg) several times it...
