Description
The study of numerical methods for the approximation of Partial Differential Equations (PDEs) on polygonal and polyhedral meshes is drawing the attention of an increasing number of researchers. Indeed, polytopal grids offer a very convenient framework to handle, for instance, hanging nodes, different cell shapes within the same mesh and nonmatching interfaces. Such a flexibility represents a powerful tool towards the efficient solution of problems with complex inclusions (as in geophysical applications) or posed on very complicated or possibly deformable geometries (as encountered in basin and reservoir simulations, in fluid-structure interaction, crack propagation or contact problems). In recent years, several discretization methods for polygonal and polyhedral meshes have been developed and there are strong connections among them. The aim of this Workshop is to bring together experts and young researchers in this field in order to discuss the most recent developments and to establish common grounds and shared goals.
Particular attention will be paid to industrial applications of polyhedral methods, which will be discussed during a dedicated session.
L’étude des méthodes numériques pour l’approximation des équations différentielles partielles (EDP) sur les maillages polygonaux et polyédriques attire l’attention d’un nombre croissant de chercheurs. En effet, les maillages généraux offrent un cadre très pratique pour manipuler, par exemple, des noeuds non-conformes, des formes de mailles différentes dans le même maillage et des interfaces non conformes. Une telle flexibilité représente un outil puissant pour la résolution efficace de problèmes avec des inclusions complexes (comme dans les applications géophysiques) ou posés sur des géométries très compliquées ou éventuellement déformables (telles que rencontrées dans des simulations de bassin et de réservoir, en interaction fluide-structure, propagation de fissures ou problèmes de contact). Ces dernières années, plusieurs méthodes de discrétisation des maillages polygonaux et polyédriques ont été développées et il existe de fortes connexions entre elles. Le but de ce workshop est de rassembler des experts et des jeunes chercheurs dans ce domaine afin de discuter des développements les plus récents et d’établir des points communs et des objectifs communs.
Une attention particulière sera portée aux applications industrielles des méthodes polyédriques, qui seront discutées lors d’une session dédiée.
