[Getdp] Internal Boundary heat source?

[Christophe Trophime]

I wish to add an internal heat source on a surface (or a line) in my
heat equation. The Flux is the heat source term.
On the internal boundary this difference of heat flux on this boundary
is equal to Flux, we have :

[k \frac{\partial T}{\partial n]_{\Gamma} = Flux

So I tried to add a term :

     Galerkin { [ Flux[] , {T} ]; In Domain_HeatFlux; 
     	Jacobian Sur ; Integration I1; }

within my heat equation formulation. 

But it do not seem to work?
Has anybody has an idea what's wrong in my formulation?
