TI - A New Application of the Panel Clustering Method for 3D SGBEM T2 - Computer Modeling in Engineering \& Sciences PY - 2003 VL - 4 IS - 1 SN - 1526-1506 AB - This paper is devoted to the study of a new application of the Panel Clustering Method [Hackbusch and Sauter (1993); Hackbusch and Nowak (1989)]. By considering a classical 3D Neumann screen problem in its boundary integral formulation discretized with the Galerkin BEM, which requires the evaluation of double integrals with hypersingular kernel, we recall and use some recent results of analytical evaluation of the inner hypersingular integrals. Then we apply the Panel Clustering Method (PCM) for the evaluation of the outer integral. For this approach error estimate is shown. Numerical examples and comparisons with classical PCM technique are presented. KW - Galerkin method KW - Boundary Element Method KW - Panel Clustering Method DO - 10.3970/cmes.2003.004.031
