How to make a interface boundary?

Hello
I am doing a evaporative cooling project. I have two domain (see the figure). One is for air, another is for water. Problem is, when I try to give flux at the interface boundary, comsol is showing it is not applicable. How can I solve this? See the figure.

I don't usually use those particular settings, but I can guess what is happening.
Internal boundaries are not in the default set; they appear as inapplicable (and act as continuity) in the default set. So you usually have to create a new boundary condition if you want something other than continuity there. In the Model Builder, under Component, find the physics-related heading (e.g., "Electromagnetic Waves" or whatever physics you are using. Right-click on that, to bring up a menu, which will include various boundary conditions to choose from. Choose one of those, corresponding to the condition you want to set on this particular boundary. This will generate a whole new entry in the list under the physics. Left-click on that entry, Now select the boundary you want from the graphics window and right-click to cause it to be loaded it into the selection box.

I would recommend you to go through evaporating cooling model available in heat transfer module. For concentration, you do not need to include water domain in transport of diluted species.
