Superconvergence of a Galerkin FEM for Higher-Order Elements in Convection-Diffusion Problems
S. Franz, H. -G. Roos
In this paper we present a first supercloseness analysis for higher-order Galerkin FEM applied to a singularly perturbed convection-diffusion problem. Using a solution decompositio…

Superconvergence Using Pointwise Interpolation in Convection-Diffusion Problems
Sebastian Franz
Considering a singularly perturbed convection-diffusion problem, we present an analysis for a superconvergence result using pointwise interpolation of Gauß-Lobatto type for higher-…
