Sliding of rough surfaces and energy dissipation with a 3D multiscale approach

Jean-François Molinari, Guillaume Anciaux

The purpose of this paper is to present a novel approach to study sliding friction by the use of 3D multiscale coupling techniques. We highlight the difficulties of using multiscale schemes that couple molecular dynamics (MD) with finite elements to perfor ...

Adaptive finite elements with large aspect ratio for electroosmotic and pressure-driven microflows

Martinus Gijs, Marco Picasso, Virabouth Prachittham

A space–time adaptive method is presented for the numerical simulation of mass transport in electroosmotic and pressure-driven microflows in two space dimensions. The method uses finite elements with large aspect ratio, which allows the electroosmotic flow ...

Influence of the implanted pulse generator as reference electrode in finite element model of monopolar deep brain stimulation

Jean-Philippe Thiran, Juan Ramon Mosig, Grégoire Walckiers, Benjamin Fuchs

lectrical deep brain stimulation (DBS) is an efficient method to treat movement disorders. Many models of DBS, based mostly on finite elements, have recently been proposed to better understand the interaction between the electrical stimulation and the brai ...

Multiscale algorithm with patches of finite elements

Jacques Rappaz, Marco Picasso, Vittoria Augusta Rezzonico Janka

We develop a discretization and solution technique for elliptic problems whose solutions may present strong variations, singularities, boundary layers and oscillations in localized regions. We start with a coarse finite element discretization with a mesh s ...

Étude des fondements physiques possibles des concepts numériques utilisés dans les méthodes d'acoustique géométrique

Thomas Guignard

The subject of the work presented here is the study of the acoustical ray method, which aims at describing a pressure field by an analogy with light rays. The concept of a wave is therefore replaced by the concept of "acoustical rays", whose paths through ...

Iterative methods for Stokes/Darcy coupling

Marco Discacciati

We present iterative subdomain methods based on a domain decomposition approach to solve the coupled Stokes/Darcy problem using finite elements. The dependence of the convergence rate on the grid parameter h and on the physical data is discussed; some diff ...

Approximation of multi-scale elliptic problems using patches of finite elements

Jacques Rappaz

In this paper we present a method to solve numerically elliptic problems with multi-scale data using multiple levels of not necessarily nested grids. The method consists in calculating successive corrections to the solution in patches whose discretizations ...
