In this paper characteristic-nonconforming finite-element methods are studied for time dependent advection-dominated diffusion problems. The diffusion term in these problems is discretized using nonconforming finite elements, and the temporal differentiation and advection terms are treated by charac

A one-dimensional singularly perturbed problem with a boundary turning point is considered in this paper. Let V h be the linear finite element space on a suitable grid T h . A variant of streamline diffusion finite element method is proved to be almost uniform stable in the sense that the numerical

A new stabilized and accurate finite element formulation for convection-dominated problems is herein developed. The basis of the new formulation is the choice of a new upwind function. The upwind function chosen for the new method provokes its degeneration into the SUPG or CAU methods, depending on

We study convergence properties of a numerical method for convection-diffusion problems with characteristic layers on a layer-adapted mesh. The method couples standard Galerkin with an h-version of the nonsymmetric discontinuous Galerkin finite element method with bilinear elements. In an associated
