[Getdp] Dual formulation for heat equation

[Amit.Itagi at seagate.com]

Hi,

I am trying to solve the heat equation  :   div(-K grad(T))=g  (in 2D).  In
the weak form, I choose T to be of Form0 and have basis BF_Node. To make
use of hp-adaptivity, I need to set up a dual problem. The dual problem
will probably be in terms of the heat flux Q=-K grad(T). I think that Q has
to be of Form2P and
have basis BF_PerpendicularFacet. Is this correct ? What will the weak form
of the dual problem look like ?

div(Q)=g  =>   ??

Thanks

Rgds,
Amit
