✦ Synopsis

Stabilized FEM of streamline-diffusion type for advection-diffusion problems may exhibit local oscillations in crosswind direction(s). As a remedy, a shock-capturing variant of such stabilized schemes is considered as an additional consistent (but nonlinear) stabilization. We prove existence of discrete solutions. Then we present some a priori and a posteriori estimates. Finally we address the efficient solution of the arising nonlinear discrete problems.

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

In this paper three characteristic mixed discontinuous finite element methods are introduced for time dependent advection-dominated diffusion problems. Namely, the diffusion term in these problems is discretized using mixed discontinuous finite elements, and the temporal differentiation and advectio

A procedure to derive stabilized space-time finite element methods for advective -diffusive problems is presented. The starting point is the stabilized balance equation for the transient case derived by On ˜ate [Comput. Methods Appl. Mech. Eng., 151, 233-267 (1998)] using a finite increment calculus
