RT Book, Section T1 A preconditioning technique for Chebyshev collocated advection diffusion operators A1 Pinelli, Alfredo A1 Benocci, C. A1 Deville, M. AB An original method for preconditioning Chebyshev collocated advection-diffusion operators is proposed. The preconditioner, based on an upwind finite difference approximation, is tested on one and two dimensional problems with both Neumann and Dirichlet boundary conditions.
