High order nonlinear numerical schemes for evolutionary PDEs : proceedings of the European workshop HONOM 2013, Bordeaux, France, March 18-22, 2013 by Rémi Abgrall( )

14 editions published between 2014 and 2016 in English and held by 382 WorldCat member libraries worldwide

This book collects papers presented during the European Workshop on High Order Nonlinear Numerical Methods for Evolutionary PDEs (HONOM 2013) that was held at INRIA Bordeaux Sud-Ouest, Talence, France in March, 2013. The central topic is high order methods for compressible fluid dynamics. In the workshop, and in this proceedings, greater emphasis is placed on the numerical than the theoretical aspects of this scientific field. The range of topics is broad, extending through algorithm design, accuracy, large scale computing, complex geometries, discontinuous Galerkin, finite element methods, Lagrangian hydrodynamics, finite difference methods and applications and uncertainty quantification. These techniques find practical applications in such fields as fluid mechanics, magnetohydrodynamics, nonlinear solid mechanics, and others for which genuinely nonlinear methods are needed

Design of an essentially non-oscillatory reconstruction procedure on finite-element type meshes by Rémi Abgrall( Book )

9 editions published between 1991 and 1992 in English and held by 93 WorldCat member libraries worldwide

Abstract: "In this report, we have designed an Essentially Non Oscillatory reconstruction for functions defined on finite-element type meshes. Two related problems are studied: the interpolation of possibly unsmooth multivariate functions on arbitrary meshes and the reconstruction of a function from its averages in the control volumes surrounding the nodes of the mesh. Concerning the first problem, we have studied the behaviour of the highest coefficients of two polynomial interpolations of a function that may admit discontinuities of locally regular curves: the Lagrange interpolation and an approximation such that the mean of the polynomial on any control volume is equal to that of the function to be approximated. This enables us to choose the best stencil for the approximation. The choice of the smallest possible number of stencils is addressed. Concerning the reconstruction problem, two methods have been studied: a first one base [sic] on an adaptation of the so-called reconstruction via deconvolution method to irregular meshes and a second one that lies on the approximation on the mean as defined above. The first method is conservative up to a quadrature formula and the second one is exactly conservative. The two methods have the expected order of accuracy, but the second one is much less expensive than the first one. Some numerical examples are given which demonstrate the efficiency of the reconstruction [sic]."
On essentially non-oscillatory schemes on unstructured meshes : analysis and implementation by Rémi Abgrall( Book )

6 editions published in 1992 in English and held by 78 WorldCat member libraries worldwide

A few years ago, the class of Essentially Non-Oscillatory Schemes for the numerical simulation of hyperbolic equations and systems was constructed. Since then, some extensions have been made to multidimensional simulations of compressible flows, mainly in the context of very regular structured meshes. In this paper, we first recall and improve the results of an earlier paper about non-oscillatory reconstruction on unstructured meshes, emphasising the effective calculation of the reconstruction. Then we describe a class of numerical schemes on unstructured meshes and give some applications for its third order version. This demonstrates that a higher order of accuracy is indeed obtained, even on very irregular meshes ... ENO Schemes, High order accuracy, Numerical shock capturing scheme, Unstructured meshes

Hypersonic flows for reentry problems by J.-A Désidéri( Book )

5 editions published between 1992 and 1994 in English and German and held by 10 WorldCat member libraries worldwide

The physical modelling and the numerical simulation of the critical reentry phase of hypersonic space vehicles are important areas of aerospace research. Eight specific problems of aerodynamics and thermodynamics were chosen as the central topics of this workshop. In these two volumes bothexperimental and computational data are collected along with comparative reviews presented at the meeting by international experts in the field of hypersonic flows. The books will be an important reference and the data will be valuable for numerical simulations of hypersonic flows and theirapplications in physics and engineering

A genuinely multidimensional Riemann solver = Un solveur de Riemann vraiment multidimensionnel by Rémi Abgrall( Book )

3 editions published in 1993 in English and held by 5 WorldCat member libraries worldwide

Abstract: "Many modern numerical method [sic] for the integration of the equation of compressible flows rely on TVD type schemes with Riemann solvers. These schemes are directly built from the generalisation of 1D numerical schemes for the Euler equations by mean [sic] of the finite volume method. Doing this, some propagation directions are priviledged [sic], the directions orthogonal to the facets of the control volumes. This may lead to large numerical errors, especially when the mesh is distorted. In this report, we compute the exact solution of the Riemann for a linear hyperbolic equation obtained from the Euler equation by linearisation. Then we show how to apply this result to construct a first order finite volume scheme that is genuinely multidimensional."

Construction simple de schémas distribuant le résidu non-oscillants et d'ordre élevé pour la simulation d'écoulements stationnaires sur maillages triangulaires et hybrides by Cédric Tavé( Book )

2 editions published in 2007 in French and held by 3 WorldCat member libraries worldwide

Nous nous intéressons dans cette thèse aux schémas numériques dits "distribuant le résidu". Cette classe de méthode s'applique aux équations de conservation, typiquement les équations de la mécanique des fluides ; la robustesse et la flexibilité de cette approche permettent de résoudre de manière précise et compacte des problèmes difficiles sur maillages non structurés. Nous présentons ici une méthodologie permettant de construire de façon automatique des schémas d'ordre élevé (deux et plus). Après avoir rappelé quelques éléments théoriques nécessaires à la compréhension de la méthode, nous tâchons de décrire la construction du schéma de façon assez simple, en illustrant la démarche par des expérimentations numériques. Les principaux avantages de la solution proposée sont les suivants : une grande facilité de mise en oeuvre, la possibilité de l'appliquer à de nombreuses discrétisations (triangulaire, quadrangulaire, tétrahèdrique, etc.) et le large éventail de problèmes pouvant être traités (mécanique des fluides, magnéto-hydrodynamique, équations de Saint-Venant,...). Les résultats numériques proposés ici peuvent être groupés en deux types. Tout d'abord, les résultats sur des problèmes scalaires permettent de valider le gain de précision apportée par la méthode (jusqu'à l'odre 4) et son bon comportement sur des maillages hybrides. Ensuite, nous nous intéresserons à la mécanique des fluides (équations d'Euler et de Navier-Stokes). En particulier, nous proposons des résultats sur le cas-test cylindre-jupe à Mach 5, où nous confrontons nos résultats avec des solutions mises à disposition par ONERA
