Hello everybody,

I am going to implement for the first time a diffusion problem with temperature dependent physical properties of the material, namely density, conductivity, specific heat and so on
How can I specify to the solver that the material properties are temperature dependent when the temperature is the solution of the PDE?
I would appreciate if you could help me or show me a tutorial I can follow

Thank you!

You can use Newton's method to solve, see the FEniCS tutorial on nonlinear methods:
