Abstract

The use of BEM in piece-homogeneous open Poisson's analysis generally leads to the solution of a linear system of equations where interface potentials and fluxes are the degrees of freedom. In this paper the change in material property is modelled as a single layer source along the interfaces that is modified every step of an iterative process. Therefore, no linear system is to be solved and po- tential value at any point is computed from a direct boundary integration. The underlying technique is the transmission-line modelling method. The perfor- mances of our method are demonstrated through a two-dimensional magnetos- tatics problem. 1 Introduction The boundary element method provides an excellent accuracy in the numerical analysis of Poisson's problem.
