Phase change effect in Simulation

Dear Comsol Users,

I would like to know if someone here has already deal with phase change effect in the simulation. I mean, like water phase change from liquid to gas --> showing the pressure and mass evolution. If it is the case, please just give me some hints that could help me. I use the Chemical Engineering and Heat Transfer Modules.

Thanks in advance for your help.
Cheers,
