I will be glad to answer more questions.

hi again, what was your approach?
(we model a laminar flow problem)
#1 Did you use the species transport model, in that case what settings?
#2 How can i put relative humidity bc at an inlet or domain?
#3 did you write your own udf for the mass transfer of condensate at the boundary, in that case how does it look like?
