Abstract:

In this paper, we present a Discontinuous Galerkin Method ( DGM ) with mass lumping and Qr aproximation for linearized Euler's equations. Mixed formulation provides low-storage for stiffness and jump matrices and the use of quadrangular meshes provides a quick algorithm.

Abstract (translation) :

Ce document presente une methode de Galerkin discontinue avec condensation de masse de type Qr adaptee aux equations d'Euler linearisees. Une formulation mixte permet de reduire significativement le stockage des matrices de rigidite et de saut et l'utilisation de maillages quadrangulaires permet un d'avoir un algorithme rapide.
