Hello,

in preparation for simulating the natural evaporation of water, I did some experiments with Ansys fluent 16.2. First I simulated boiling water with VOF and everything works as expected. But if I lower the temperature of the heater below the saturation temperature of the water, there is no evaporation at all. Am I doing something wrong or is fluent 16.2 not able to simulate natural evaporation? Are there some improvements in the current version of Ansys?
Thanks in advance
