Dear Comsol user,
I have one conceptual question...
I would like to model phase change of solid due to heat transfer from fluid above. Intuitively i should model the melting of solid using " heat transfer with phase change". But in different examples it is modeled differently. I found three examples till now "Cooling and Solidification of Metal" , "Tin Melting Front" and one with phase change of ice.
Use of either deformed geometry or phase change should give me the same result.
What is the difference between both of the approaches?

Dear Francois,
Can you tell me how to find the direction of normal vector at an interface? This interface is modeled as deformed geometry, thus i want to know the normal vector in order to specify the "prescribed normal mesh velocity".
I couldn't locate it in the expression options for deformed geometry or geometry in itself.
Kind Regards
Parth
