The ε‐Uniform Convergence of a Defect‐Correction Method on a Shishkin Mesh

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001
AbstractA defect correction method based on finite difference schemes is considered for a singularly perturbed boundary value problem on a Shishkin mesh. The method combines the stability of the upwind difference scheme and the higher‐order accuracy of the central difference scheme.

A streamline diffusion finite element method on a shishkin mesh for a convection-diffusion problem

Rendiconti del Seminario Matematico e Fisico di Milano, 1994
A model of the time-dependent convection-diffusion problem whose solution may exhibit interior and boundary layers is considered. The standard streamline diffusion scheme, with piecewise linear elements on a uniform mesh for such a problem is convergent only at points that are not close to any layer. The main of the paper is to replace the uniform mesh
