Metal melting simulation.

Hi everyone,

I'm trying to simulate the melting of metal (Cu) using the Heat transfer module.
I have already done phase changes from solid to liquid (melting point) like as Continuous Casting model.
Could you help me please with phase changes from liquid to gas phase (boiling point), like this:

What module and logic are used in this video to do evaporation of material?

Thanks,
James
