We study nonstationary iterative methods for solving preconditioned systems arising from discretizations of the convection-diffusion equation. The preconditioners arise from Gauss-Seidel methods applied to the original system. It is shown that the performance of the iterative solvers is affected by

Discretization of boundary integral equations leads, in general, to fully populated complex valued non-Hermitian systems of equations. In this paper we consider the e cient solution of these boundary element systems by preconditioned iterative methods of Krylov subspace type. We devise preconditione
This paper investigates the performance of preconditioned Krylov subspace methods used in a previously presented two-fluid model developed for the simulation of separated and intermittent gas -liquid flows. The two-fluid model has momentum and mass balances for each phase. The equations comprising t
