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 numerically(More)
Based on approximation of the balance relation for convection-diffusion problems, finite difference schemes on rectangular locally refined grids are derived and studied. A priori estimates and error bounds in discreteH 1-norm are provided. Numerical examples demonstrating the accuracy of the schemes for a variety of model convection-diffusion problems are(More)
