Abstract
This paper tests a number of incomplete lower-upper (ILU)-type precondition ers for solving indefinite linear systems, which arise from complex applica tions such as computational fluid dynamics (CFD). Both point and block prec onditioners are considered. The paper focuses on ILU factorization that can be computed with high accuracy by allowing liberal amounts of fill-in. A n umber of strategies for enhancing the stability of the factorizations are e xamined. Copyright (C) 2000 John Wiley & Sons, Ltd.
