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:

#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.
