Hello all
I'm trying to use the adaptive refinement capabilities of deal.ii. I was reading step 6, where adaptivity is introduced for first time. I have two questions: The kelly error estimator expects a map with relations between boundary indicators and corresponding objects describing neumann boundary values. So, for what I understand if I have, lets say, 2 boundaries with indicators '1' and '2', I need to put them in the map function with the respective functions that gave me the values for these boundaries. Something like: '1' boundary_function_1() '2' boundary_function_2() How do I define this map function? And, what happen if I use robin boundary conditions? Do I need to put them in the map function? If so, how do I do it? Finally, I would like to expose what is the problem I'm trying to solve because I'm not sure if the way I'm doing it the more efficient one (probably not). Any advice would be highly appreciated. The problem is a heat pipe. I have a 3d cubic domain with a cylindrical hole. The problem equation in the cube domain is heat diffusion and is subjected to robin and neumann boundary conditions on the external surfaces and a robin boundary condition on the hole surface. This boundary condition depends on the solution of a 1d advection problem. The 1d domain has an internal heat generation depending on the values on the internal hole surface in the 3d domain. I iterate the assembling and solve steps until the difference in both norm solutions is less than .5.
