Convection-diffusion problems, SDFEM/SUPG and a priori meshes

This paper aims to give the reader a summary of current understanding of the streamline-diffusion finite element method (SDFEM), as applied to linear steady-state convection-diffusion problems. Towards this end, we begin with a brief description of the nature of convection-diffusion problems: the structure of their solutions will be examined, with special emphasis o
