Necessary conditions for uniform convergence of finite difference schemes for convection-diffusion problems with exponential and parabolic layers

Hans-Görg Roos, Martin Stynes (1996)

Similarity:

Singularly perturbed problems of convection-diffusion type cannot be solved numerically in a completely satisfactory manner by standard numerical methods. This indicates the need for robust or ϵ -uniform methods. In this paper we derive new conditions for such schemes with special emphasize to parabolic layers.
