Abstract
In this paper we investigate the performance of CGS, BCGSTAB and GMRES with ILU preconditioner for solving convection-diffusion problems. Nu merical experiments indicate that BCGSTAB appears to be an efficient a nd stable method. CGS sometimes suffers from severe numerical instabil ity. GMRES shows a higher suitability and stability but the overall co nvergence rate may be lower.
