Frequency of lee model at Fluent 2021 R1
 

Hello,

I have a question about Lee model of new version Fluent.
When I use Lee model, I need to set evaporation frequency and condensation frequency. In Fluent 2021 R1, their names are changed. Instead of evaporation frequency and condensation frequency, there are "from phase frequency" and "to phase frequency". Which is evaporation frequency, "from phase frequency" or "to phase frequency"?
Does phase mean main phase?

Thank you.

"In the Evaporation-Condensation Model dialog box, the Evaporation Frequency and Condensation Frequency text entry fields (Model Constants group box) have been renamed for clarity to From Phase Frequency and To Phase Frequency, respectively."

Can you specify about the primary phase and secondary phase also please specify "To phase" and "From phase" in the mass transfer mechanism?
thanks in advance
