✦ Synopsis

Multidimensional residual distribution schemes for the convectiowdiffusion equation are described. Compact upwind cell vertex schemes are used for the discretization of the convective term. For the diffusive term, two approaches are compared the classical finite element Galerkin formulation, which preserves the compactness of the stencil used for the convective part, and various residual-based approaches in which the diffusive term, evaluated after a reconstruction step, is upwinded along with the convective term.

A multidimensional discretisation of the shallow water equations governing unsteady free-surface flow is proposed. The method, based on a residual distribution discretisation, relies on a characteristic eigenvector decomposition of each cell residual, and the use of appropriate distribution schemes.

This paper is concerned with the development of the finite element method in simulating scalar transport, governed by the convection-reaction (CR) equation. A feature of the proposed finite element model is its ability to provide nodally exact solutions in the one-dimensional case. Details of the de
