Abstract

We present a numerical study for singularly perturbed convectiondiffusion problems using higher order Galerkin and streamline diffusion finite element method. We are especially interested in convergence and superconvergence properties with respect to different interpolation operators. For this we investigate pointwise interpolation and vertex-edge-cell interpolation. (C) 2012 Wiley Periodicals, Inc. Numer Methods Partial Differential Eq, 2013
