Question regarding the selection of primary phase and secondary phase for Lee model

Hello,

          I apologize if this issue has already been discussed before. My question is while selecting the primary and secondary phases for VOF- Lee evaporation condensation model is there any recommendation to choose the vapor phase as primary and liquid phase as secondary or is it the other way round?

When I choose vapor as the primary and liquid as secondary phase, I could not get condensation but when the liquid phase is chosen as a primary phase and vapor phase as a secondary phase, I could see condensation occurring in my simulations. 

PS: The evaporation and condensation frequency is left default as 0.1, while the mass transfer phase interaction is from liquid to vapor in both the scenarios.
