— SparSol is a software package intended for the preconditioned iterative solution of large sparse linear systems. It includes sets of iterative methods, preconditioners, scaling and reordering algorithms that allows to choose the optimal combination of algorithms for a particular problem. The paper briefly describes the algorithms implemented and(More)
We consider cell-centered nite diierence discretizations with local reenement for nonsymmetric boundary value problems. Preconditioners with mesh independent convergence properties for corresponding matrices are constructed. The method is illustrated with numerical experiments. 1. Introduction This paper is devoted to construction of preconditioners of(More)
