Academic Work

I've been studying physics and especially acoustics for the past five years at the Université du Maine in Le Mans, France. The cursus was mainly about physical acoustics, signal analysis, vibroacoustics, mechanics & fluid dynamics. The first two years were held in common with a bachelor degree in computer sciences (C programming language, web development, etc.).

Modelling framework for thin interfaces - MSc 2 final project

The end of the Master degree comprises a report (master thesis) discussing the outcomes of a 4 to 6 months internship.

I realised mine at the Royal Institute of Technology (KTH, Stockholm, Sweden) under the supervision of Pr. Olivier Dazel and Pr. Peter Göransson. Conducted in the Marcus Wallenberg Laboratory, the internship was about modelling thin interfaces for multilayer systems involving porous materials.

We studied different types of porous films, their effect on the system's performance and implemented a hybrid FEM-based method to account for the propogation through films without meshing them.

As a conclusion, we analysed the sensibility of the model to randomness of some parameters (airflow resistivity, etc...) and discussed the usability of the hybrid method to model uncertainties on thin interfaces.

DGM/FEM Coupling - MSc 1 final project

A great part of my first year of MSc was evaluated on a 4-6 months project.

Mine was completed under supervision of Pr. Olivier Dazel and treated the subject of coupling between Finite Elements and Discontinuous Galerkin Methods. The project relied heavily on the work of Dr. Gwenaël Gabard, from the University of Southampton, and Oliver on the usage of a set of plane waves as an expansion basis for DG method. He, Gwenaël, also took part in the project.

We discussed the mathematical formulations of both methods and expressed the boundary operators in a way allowing coupling. Finally, noting a loss of one convergence order, we experimented the use of Hermite polynomials as a interpolation basis for FEM which led to better results.

The method devised in this work was implemented in PLANES, a porous materials simulator from the LAUM.

The report (in french) can be downloaded from Github : Couplage des méthodes FEM et DGM (fr)

The project was interesting enough to be discussed in a talk held by Olivier at the French Congress of Mechanics in Lyon, August 2016. The slides can be found here : Couplage FEM/DGM avec ondes planes (fr)
