Hi
I am a Dolfin newbie trying to solve a steady heat conduction problem div(K grad u) + f = 0 For constant scalar K the variational form (I am using the Python interface) K*dot(grad(v),grad(u))*dx works OK. The problem is that I do not know how to instruct Dolfin to deal with the case where K=K(x) is a (symmetric) tensor field (anisotropic heat conduction). Any help is appreciated. -- Best regards Heitor Pina
