Abstract

The standard Boundary Integral Equation Method generally results in dense and nonsymmetric algebraic equations. To speed up the computations, spe- cial techniques are needed. In this paper a multigrid method is presented applied to boundary integral equations. The main idea of the method is to convert a mixed boundary value problem to a sequence of pure Dirichlet and Neumann subproblems. To evaluate the appearing boundary integral operators, a special panel clustering method based on the fast multipole evaluation technique is applied. A completely different multigrid approach for solving the scattered data interpolation problem arising in the dual reci- procity method is also presented. 1 Introduction The usual discretisation techniques
