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

New book: Complex fluids: Modeling and Algorithms

Pierre Saramito, Complex fluids: Modeling and Algorithms, Springer, 2016

This book presents a comprehensive overview of the modeling of complex fluids, including many common substances, such as toothpaste, hair gel, mayonnaise, liquid foam, cement and blood, which cannot be described by Navier-Stokes equations. It also offers an up-to-date mathematical and numerical analysis of the corresponding equations, as well as several practical numerical algorithms and software solutions for the approximation of the solutions. It discusses industrial (molten plastics, forming process), geophysical (mud flows, volcanic lava, glaciers and snow avalanches), and biological (blood flows, tissues) modeling applications. This book is a valuable resource for undergraduate students and researchers in applied mathematics, mechanical engineering and physics.
