Finite difference methods for hyperbolic PDEs like the wave equation: Lax–Friedrichs method — first-order explicit Lax–Wendroff method — second-order explicit MacCormack method — second-order explicit Upwind scheme Lax–Wendroff theorem — conservative scheme for hyperbolic system of conservation laws converges to the weak solution.

Traditionally, low-order numerical schemes, for instance classical finite volume (FV) methods, have been used to solve hyperbolic conservation laws, particularly in industrial applications.

But since they become quite costly for high accuracy or long time simulations, there is a rising demand of high-order (third and above) by: 1. 7-Volume Set now available at special set price.

Over the second half of the 20th century the subject area loosely referred to as numerical analysis of partial differential equations (PDEs) has undergone unprecedented development. At its practical end, the vigorous growth and steady diversification of the field were stimulated by the demand for accurate and reliable tools for computational.

The carefully reviewed selection of the papers will provide the reader. Solving non conservative hyperbolic systems is a delicate problem because the definition of weak admissible solutions is difficult. Here, we consider the weak solutions obtained by the fluid limit of an underlying two species polyatomic kinetic model coupled with the Poisson and Ampère equations.

The resulting model consists of a system of hyperbolic conservation laws, which, in a relaxation limit, exhibit the correct diffusive properties given by the variance of the observed data. Controlling a re-entrant manufacturing line via the push-pull point Dominique Perdaen, Dieter.
