Hi all, i need help with following problem:
I have a 2D Convection-Diffusion Equation and a 1D first order ODE, which is coupled by boundary-condition. (i need the concentration_solution for computing the ODE and the solution of that ODE on the other hand is part of the neumann-BC in the 2D Equation). Assembling and solving of the 2D problem works well, but i don't know how to setup the sytem including the 1D (boundary-) ODE. I need a second dof_handler and sparsity_pattern only for the neumann-boundary where the ODE is define, don't I? How can i create all these only on a boundary? Thanks in advance.
