00925njm 22002777a 4500 dc Pinelli, Alfredo author Benocci, C. author Deville, M. author 1994 An original method to precondition Chebyshev collocated advection-diffusion operators is proposed. 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. 0045-7825 10.1016/S0045-7825(94)80024-3 https://hdl.handle.net/20.500.14352/58580 http://www.sciencedirect.com/science/article/pii/S0045782594800243 http://www.sciencedirect.com/ A Chebyshev collocation algorithm for the solution of advection—diffusion equations
