Moreover Poisson equation, being a Linear PDE, is essentially solved using convolutions.
The crux of the problem seems to be in the handling of boundaries - once FEM-ized the nice grid like structure gets replaced by an irregular graph (with similar topological dimension). Can someone please shed some light on this ?
