[Getdp] Heat Problem

[sdurand]

Hello,

You are missing some Jacobian terms (JacNL) in the formulation of your
problem. If you want to solve a nonlinear problem by Newtons method, you
need to define extra terms in the formulation using the JacNL-command
(there is an example of this in the GetDP-wiki for nonlinear
magnetostatics). I think this might solve your problem.

Regards!
Stephane
