Wikie is on a distinguished road

my problem I'm trying to simulate is similar to cooling towers. My droplets are falling due to the gravity. The droplets will evaporate and cool down, the air will heat up and the humidity will increase.
For this I turned on the follwing models: Energy - On; Species - Species Transport; Discrete Phase - On.
I'm using the DPM to simulate the droplets and I use a group injections. I also adjusted the vapour pressure.
One big problem that occours is, that my rel. humidity increases obove 100%.
How can I adjust the evaporation that it will not continue when the humidity reach 100%??

cheers wikie
