Parallel finite-element codes for the Bogoliubov-de Gennes stability analysis of Bose-Einstein condensates
Georges Sadaka, Pierre Jolivet, Efstathios G. Charalampidis +1
We present and distribute a parallel finite-element toolbox written in the free software FreeFem for computing the Bogoliubov-de Gennes (BdG) spectrum of stationary solutions to on…
A finite element toolbox for the Bogoliubov-de Gennes stability analysis of Bose-Einstein condensates
Georges Sadaka, Victor Kalt, Ionut Danaila +1
We present a finite element toolbox for the computation of Bogoliubov-de Gennes modes used to assess the linear stability of stationary solutions of the Gross-Pitaevskii (GP) equat…
Coupling Navier-Stokes and Gross-Pitaevskii equations for the numerical simulation of two-fluid quantum flows
Marc Brachet, Georges Sadaka, Zhentong Zhang +2
Numerical methods for solving the Navier-Stokes equations for classical (or normal) viscous fluids are well established. This is also the case for the Gross-Pitaevskii equation, go…
Identification of vortices in quantum fluids: finite element algorithms and programs
Victor Kalt, Georges Sadaka, Ionut Danaila +1
We present finite-element numerical algorithms for the identification of vortices in quantum fluids described by a macroscopic complex wave function. Their implementation using the…
Boussinesq-Peregrine water wave models and their numerical approximation
Theodoros Katsaounis, Dimitrios Mitsotakis, George Sadaka
In this paper we consider the numerical solution of Boussinesq-Peregrine type systems by the application of the Galerkin finite element method. The structure of the Boussinesq syst…
Metabolic Flux Analysis in Isotope Labeling Experiments using the Adjoint Approach
Stéphane Mottelet, Gil Gaullier, Georges Sadaka
Comprehension of metabolic pathways is considerably enhanced by metabolic flux analysis (MFA-ILE) in isotope labeling experiments. The balance equations are given by hundreds of al…
FullSWOF_Paral: Comparison of two parallelization strategies (MPI and SKELGIS) on a software designed for hydrology applications
Stéphane Cordier, Hélène Coullon, Olivier Delestre +4
In this paper, we perform a comparison of two approaches for the parallelization of an existing, free software, FullSWOF 2D (http://www. univ-orleans.fr/mapmo/soft/FullSWOF/ that s…
Generation and propagation of a Tsunami wave : a new mesh adaptation technique
Georges Sadaka
The importance of the study of the propagation of a Tsunami wave came from the complex phenomenon and its natural disasters which represents a major risk for populations. To model…
FreeFem++, a tool to solve PDEs numerically
Georges Sadaka
FreeFem++ is an open source platform to solve partial differential equations numerically, based on finite element methods. It was developed at the Laboratoire Jacques-Louis Lions,…
Solution of 2D Boussinesq systems with FreeFem++: The flat bottom case
Georges Sadaka
We consider here different family of Boussinesq systems in two space dimensions. These systems approximate the three-dimensional Euler equations and consist of three coupled nonlin…
