Thanks for the reply. I will look into it.

I have a basic doubt regarding evaporation and condensation in multiphase simulations. The problem is as follows:

I have a chamber that contains a mixture of moisture (air + water vapor) and liquid water at atmospheric pressure with a relative humidity of 50%. My goal is to simulate the evaporation of the liquid water into the air. I expect the evaporation to occur well below 100°C. How should I set the conditions to induce evaporation? Additionally, I need to ensure that the evaporation stops once the air becomes fully saturated with water vapor.

I am confused about the default saturation temperature of 100°C. Does the saturation temperature of 100°C imply that boiling will occur at those conditions?
