The old version which came from an FEM simulation had significant errors towards the edges, possibly because the simulation volume was chosen too small. The potential dropped much too slowly towards the image edges. In contrast, the analytic solution is very simple, as the potential is just the linear sum of two 1/r potentials. | |
