چکیده

— We study her e the convergence of Finite Volume schemes of monotone type for gênerai multidimensional conservation laws. By generalizing a previous result of Kuznetsov for Finite Différence schemes, we obtain under gênerai assumptions error bounds in h when the initial condition lies in BV (U) ; convergence follows for initial conditions in L (U) C\ L (U), Résumé. — On étudie ici la convergence de schémas aux Volumes Finis de type monotone pour des lois de conservation multi-dimensionnelles générales. En généralisant un résultat antérieur de Kuznetsov pour des schémas aux Différences Finies, on obtient sous des hypothèses générales des majorations d'erreur en h lorsque la condition initiale est dans BV(U) ; la convergence en découle pour des conditions initiales dans L(IR) n L(U).

Convergence and Error Estimates of Relaxation Schemes for Multidimensional Conservation Laws

M. A. Katsoulakis, G. Kossioris and Ch. Makridakis Abstract. We study discrete and semidiscrete relaxation schemes for multidimensional scalar conservation laws. We show convergence of the relaxation schemes to the entropy solution of the conservation law and derive error estimates that exhibit the precise interaction between the relaxation time and the space/time discretization parameters of t...

A priori error estimates for numerical methods for scalar conservation laws. Part II : flux-splitting monotone schemes on irregular Cartesian grids

This paper is the second of a series in which a general theory of a priori error estimates for scalar conservation laws is constructed. In this paper, we focus on how the lack of consistency introduced by the nonuniformity of the grids in uences the convergence of ux-splitting monotone schemes to the entropy solution. We obtain the optimal rate of convergence of ( x)1=2 in L1(L1) for consistent...

Convergence of monotone finite volume schemes for hyperbolic scalar conservation laws with multiplicative noise

We study here the discretization by monotone finite volume schemes of multi-dimensional nonlinear scalar conservation laws forced by a multiplicative noise with a time and space dependent flux-function and a given initial data in L(R). After establishing the well-posedness theory for solutions of such kind of stochastic problems, we prove under a stability condition on the time step the converg...

Finite volume methods: foundation and analysis

Finite volume methods are a class of discretization schemes that have proven highly successful in approximating the solution of a wide variety of conservation law systems. They are extensively used in fluid mechanics, meteorology, electromagnetics, semi-conductor device simulation, models of biological processes and many other engineering areas governed by conservative systems that can be writt...

Convergence of High Order Finite Volume Weighted Essentially Nonoscillatory Scheme and Discontinuous Galerkin Method for Nonconvex Conservation Laws

In this paper, we consider the issue of convergence toward entropy solutions for high order finite volume weighted essentially non-oscillatory (WENO) scheme and discontinuous Galerkin (DG) finite element method approximating scalar nonconvex conservation laws. Although such high order nonlinearly stable schemes can usually converge to entropy solutions of convex conservation laws, convergence m...
