Simulation numérique d'écoulements compressibles complexes par des méthodes de type Lagrange-projection : applications aux équations de Saint-Venant

Autor: Stauffert, Maxime

On étudie dans le cadre de la thèse une famille de schémas numériques permettant de résoudre les équations de Saint-Venant. Ces schémas utilisent une décomposition d'opérateur de type Lagrange-projection afin de séparer les ondes de gravit�

A large time-step and well-balanced Lagrange-Projection type scheme for the shallow-water equations

Autor: Chalons, Christophe, Kestener, Pierre, Kokh, Samuel, Stauffert, Maxime

This work focuses on the numerical approximation of the Shallow Water Equations (SWE) using a Lagrange-Projection type approach. We propose to extend to this context recent implicit-explicit schemes developed in the framework of compressibleflows, wi

International audience; In this work, we explain how a classical nodal Discontinuous Galerkin (DG) method for conservation laws can be modified to be geometrically exact with respect to CAD (Computer-Aided Design) data. The proposed approach relies o

A well-balanced Discontinuous-Galerkin Lagrange-Projection scheme for the Shallow Water Equations

Autor: Chalons, Christophe, Stauffert, Maxime

This work considers the Shallow Water equations (SWE) and proposes a high order conservative scheme based on a Lagrange-Projection decomposition. The high order in space and time are achieved using Discontinuous-Galerkin (DG) and Runge-Kutta (RK) str
