Accuracy Investigation of FDM, FEM and MoM for a Numerical Solution of the 2D Laplace’s Differential Equation for Electrostatic Problems

Laplace’s differential equation is one of the most important equations which describe continuity a system in various fields engineering. As gets more complex, need for solving this numerically rises. In paper we present an accuracy investigation three significant numerical methods used computational electromagnetics by applying them to solve two-dimensional domain with Dirichlet boundary conditions. We investigate influence discretization on relative error obtained each method. point out advantages and disadvantages investigated emphasis hardware requirements achieving certain accuracy.
