Default Condensation of humid air on a cold surface (VOF - Lee, species transport)

Tarantino is on a distinguished road
I want to simulate humid air condensation on a cold surface. The geometry includes two channels with a joined blade in between.
I simulated humid air using “species transport” and condensation using VOF, Lee model. A UDF imposes the saturation Temperature.
The problem I face is that I got very small (negligible) condensation on the blade although we expect a clear formation of water on the blade.
I tried a variety of settings, however, none works!!
Any hint what might be the problem?
