• NUMERICAL SOLUTIONS OF LAPLACE EQUATION
Abstract
In this paper, Laplace equation will be solved in rectangular and non-rectangular domains. The solution is done using two methods. The first method is finite difference method with two different operators of Laplace equation (five and nine-points). The second method is finite element method. A comparison took place between the three results (The two result by finite difference and the one taken from finite element method). The best result found from comparison is the nine-points method (the result was more accurate than the other two methods especially in regular domain). The conclusion from this paper is that the nine-point method is the most accurate method.
