I am trying to determine the melting depth in my material as a result of my heat source.

The result I aim to obtain from COMSOL is of this plot.

Can someone give me an idea on how to obtain it?

Thanks.

Oluwasogo, I recommend you have a look at the Tin Melting Front model: https://www.comsol.com/model/tin-melting-front-6234

Dear Amin,

I have checked it out. Is there a mathematical expression to call out the melt depth in the result section?

Dear Amin,

You may try integrating a function which is 1 in the liquid and 0 in the solid. Let Tm be the melting point. Then the function is:

if(T<Tm,0,1)

and the liquid depth is:

intop1(if(T<Tm,0,1))
