I would like to seek help regarding the implementation of radiative losses in
thermal model as a BC which will make the system non linear. So it would be
much helpful if someone could direct to relevant tutorial program implementing
the above BC.
Pushkar,
these sorts of nonlinear boundary conditions are generally included into the
weak formulation of the problem via Neumann boundary conditions. Your weak
formulation then becomes nonlinear, and if you take a look at step-15, you
will see how this kind of problem should be solved.
(You could also look at the new step-72 and step-77 programs to see how
certain aspects of this could be simplified.)
