I am actually now writing a demo on this, but have not yet finished the FEM solver to solve Poisson on 2D, so I'll let you know soon what I find and if get into the same problem as you have ;) meanwhile, I have a Mathematica demo solving the same problem you are solving but using finite difference (a little easier I think than FEM), and direct solver, may be we can compare results? I have an option to show the solution grid. here it is: http://12000.org/my_notes/mma_demos/KERNEL/KERNEL.htm #25 on the table. It is CDF. Will update this when I finish the FEM solver, or make a new one just for FEM, since that is more complicated. --Nasser
