Default How to write my own phase change with VOF method

yamifm0f is on a distinguished road

Can anybody help me on how I can implement my own phase change model?
I am in dire need to have a working interface evaporation with the VOF method.
unfortunately, StarCCM+ do not have good phase change models. The evaporation model implemented does not even work for some reason and in order to activate it I need to choose multicomponent liquid and multicomponent gas which I do not need for my problem and even if I wanted to use it I can not use water as one phase and steam as the second.

I also want to find a way to implement a thermal boundary layer from the wall with a natural convection equation. but I do not know how to do that as starccm+ does not give me that option (or I just did not find it yet).
