Variable Step/Order Generalized Upwind Methods for the Numerical Solution of Second Order Singular Perturbation Problems
Issues 1-2 Volume 04Keywords: Two-point Boundary Value Problems, singular perturbation problems, finite difference schemes, upwind method, mesh variation. Abstract: We propose a simple and quite efficient code to solve singular perturbation problems when the perturbation parameter ? is very small. The code is based on generalized upwind methods of order ranging from 4 to 10 and uses highly […]
