New book: Méthodes Level Set pour l’interaction fluide-structure

by Georges-Henri Cottet, Emmanuel Maitre, and Thomas Milcent

Springer, 2021 : https://www.springer.com/gp/book/9783030700744

About this textbook:

Les modèles eulériens sont devenus dans les quinze dernières années des outils populaires pour étudier les interactions fluide-structure, car, au contraire des méthodes plus classiques de type ALE, ils permettent de résoudre numériquement ces problèmes en se ramenant à une grille et une méthode de résolution unique pour les différents milieux.

Ce livre s’intéresse à cette classe de modèles en adoptant le point de vue original des méthodes level-set, utilisées à la fois pour suivre les interfaces fluide-solide, représenter les contraintes élastiques des solides et modéliser les forces de contact entre solides. Il combine un éclairage mathématique des modèles, des aspects d’analyse numérique, des codes élémentaires et des illustrations numériques permettant au lecteur de se faire une idée des domaines d’application et des performances de ces modèles.

Les pré-requis nécessaires pour profiter pleinement de son contenu font partie du bagage scientifique d’élèves de niveau master en mathématiques appliquées ou mécanique théorique. Il sera un outil pédagogique fructueux pour des cours de deuxième année de master ou de début de thèse, ainsi que pour des chercheurs voulant aborder ou approfondir ce domaine.

MPARME: A joint ANR (Grenoble) – FNS (ETH Zurich) project on multi-resolution particle methods for two-phase flows

In multi-phase flows the interactions between phases further increase the already stringent requirements on methods and software capabilities for flow simulations.
The computational elements have to resolve a multitude of scales, handle the physics imposed by the different phases and capture their interfaces.
By their adaptivity, accuracy and robustness, particle methods provide desirable methods to address these issues.
In this project we will develop multi-resolution semi-largrangian particle methods and software that can harness the capabilities of supercomputing architectures to simulate multi-phase flows. We will also consider hybrid strategies where different computational blocks and algorithms are distributed to heterogeneous hardware (CPU/GPU) to optimize the parallel scalability of the software.

Fernando Guevara Vasquez is visiting us

Fernando Guevara Vasquez, Assistant Professor at University of Utah, is visiting us for the whole academic year.

His reasearch deals with inverse problems and in particular cloacking. However he did not manage to cloack himself and you can easily meet him in the laboratory. We added him to the Faculty list of the team, taking into account the very precise FAQ of his web page 😉

JEARA: PDE days of the Auvergne-Rhône-Alpes region

Every year PDE people from the Auvergne-Rhône-Alpes region gather for two days.

In 2017 they will gather at the ENS in Lyon on October 19th and 20th.

The full programme can be found on the JEARA web page: http://math.univ-lyon1.fr/~jera/2017.html
