摘要

In this paper the boundary element method (BEM) is used iteratively in order to implement numerically the alternating algorithm proposed by Kozlov et al.(Kozlov, V. A., Maz'ya, V. G. & Fomin, A. V. Comput. Maths. Math. Phys., 1991, 31, 45-52) For solving the Cauchy problem for the Laplace equation. Various types of Convergence and accuracy criteria, and boundary condition formulations are Investigated which confirm that the iterative BEM produces a convergent and Accurate numerical solution with respect to the number of boundary elements and Number of iterations.
