Numerical Treatment of Viscous Flows Against Bodies with Corners and Edges by Boundary Element and Multigrid Methods

摘要

The slow viscous flow past a spatial body with corners and edges is investigated mathematically and numerically by means of a boundary element method. For the resulting algebraic system a multigrid solver is designed and analyzed. It proves to be preferable to that introduced earlier for related problems. A numerical example illustrates some of the proposed methods. (ERA citation 13:015748)
