Laplace Equation Numerical Solution

Click For Summary
SUMMARY

The discussion focuses on incorporating point charges into the numerical solution of the Laplace equation. Participants suggest using conformal mapping techniques, particularly an inversion at the point charge location. Additionally, the idea of modeling the charge as a square and analyzing the limit as it shrinks to a point is proposed as a viable approach. These methods are essential for accurately solving electrostatic problems involving point charges.

Homework Statement
Place a charge of +1 mC at the centre of the square, and initially
using the relaxation method, solve the potentials inside the grid for
the boundary conditions:
• N=S=E=W=10 V
• N=S=10 V; E=W=−10 V
• N=0 V; E=10 V; S=20 V; W=30 V
Relevant Equations
Laplace Equation, Poisson equation
I wonder how to incorporate point charge?

Perhaps an application of conformal mapping, with an inversion at the point?
Or maybe make it a square too, then take the limit as it shrinks to a point.
