Thanks Daniel for the fast answer as always. I am a bit confused : if I understood correctly, in this example, the boundary condition is that the normal component of the gradient of c is equal the velocity of the interface. and as you know the velocity of the interface (supposed to be

Hi Daniel, I was also thinking about two conditions : condition 1 : for the boundary of the diffusion of C instead of a condition on grad(c) like in the example, I was thinking of a condition on c directly : c=0 at the interface; condition 2 : definition of the speed of the interface instead
