Dear Lorenzo,
It depends how you will solve the (non-linear) problem. If you intend to use a fixed point algorithm, you can use a non-homogeneous coefficient k describe on a finite element and update its value with respect to the temperature, iterating on the resolution of linear problems. If you want to solve directly the problem, then you need to describe the corresponding tangent terms. Unfortunately, for the moment, there is no automatic way to do this. In C++, you have to use the nonlinear terms and write specific assembly procedures (not well documented, I admit). Yves. Le 02/04/2013 09:48, Lorenzo.iron a écrit :
