Hi all,
I posted a dozen of days ago in search for help for a solver of pure conduction with different diffusivity values.
Now that I solved that problem, I'm trying to get a solution for a domain with third kind boundary conditions, so that, at the wall S:

h*(T_i - T_s) = k*grad(T)

I've seen that there is the possibility of using a mixed condition, but it has to be defined explicitly rather than implicitly, with two values, one for temperature and one for the gradient, and a weight ranging from 0 to 1.

I've tried many combinations but none seems to give me the expected results.

Any clue about it?

thanks in advance
