Hughes2d (2025-)

Hughes2d is a Python library for approximating the solutions of a macroscopic pedestrian flow model named the Hughes’ model. The package combines a finite volume scheme for the scalar conservation law and a fast marching algorithm for the Eikonal equation.
Developer: T. Girard
Support: ANR COSS project (ANR-22-CE40-0010)
Licence GNU General Public Licence v3.0.

SWASHES: Shallow-Water Analytic Solutions for Hydraulic and Environmental Studies (2011-)

SWASHES is a library of analytic solutions for hydraulic and environmental studies.
Persons in charge for the code development: C. Lucas et F. Darboux (INRAE).
Developers: O. Delestre et P.-A. Ksinant-Garcia.
Support: ANR METHODE (2008-2011) (S. Cordier).

B-Growth: Bubble growth in magmas (2008-)

This program has been developed in the context of the ERC-DEMONS project. It solves a coupled system
of two non-linear differential equations and a diffusion equation, modeling the growth of a single gas bubble in a viscous fluid and undergoing decompression and diffusion (exsolution).
Person in charge for the code development: A. Burgisser (ISTerre).
Developers: L. Forestier-Coste et S. Mancini.
Support: ERC-DEMONS (2008-2012) (A. Burgisser, F. James et S. Mancini).

mixtools (2007-)

This package for the R statistical software, provides a set of functions for analyzing a variety of finite mixture models. These functions include both traditional methods, such as EM algorithms for several univariate and multivariate parametric mixtures, and newer methods that reflect some recent research in finite mixture models, such as « EM-like » algorithms for various nonparametric multivariate mixture models.
Person in charge for the code development: D. Chauveau.
Main developers: D. Young, D. Chauveau,  D. Hunter (Penn State).
