The dependence of the computation of advective-diffusive transport phenomena on the orientation of the mesh with respect to the flow direction is analyzed. Poor performance of the classical Galerkin finite-element method in the convectiondominated regime is alleviated by stabilization. We propose de

In a previous paper a general procedure for deriving stabilized ®nite element schemes for advective type problems based on invoking higher order balance laws over ®nite size domains was presented. This provides an expression for the element stabilization parameter in terms of the solution residual a
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
