The preconditioner, based on an upwind finite difference approximation, is tested on one- and two-dimensional problems. The preconditioner behaves efficiently for advection-dominated cases and produces rates of convergence independent of the number of nodes. Finally, an 'ad hoc' designed multi-domain strategy is introduced.journal articlehttp://www.sciencedirect.com/science/article/pii/S0045782594800243http://www.sciencedirect.com/metadata only access531Física (Física)22 Física
