The research performed by the Mathematical Modelling and Scientific Computing (MMCS) team is concerned with applied mathematics and their interactions, with the following objectives : understanding phenomena through modeling, doing a mathematical and numerical analysis of the models, and building efficient algorithms for computer simulations.
The models which are studied are based on (elliptic, parabolic, hyperbolic, kinetic, dispersive) Partial Differential Equations, variational inequalities, Ordinary Differential Equations, dynamical systems, homogenization theory, multiscale approaches, calculus of variations, geometric measure theory, optimal control, etc. Most of the studies of the team use deterministic models, but others also include stochastic approaches (diffusion limits, regularization by noise).
The numerical methods which are used to approximate solutions are finite differences, finite elements, finite volume methods, discontinuous Galerkin methods, decomposition domain methods, spectral methods. Codes are developped, and at a larger scale parallelization techniques are used. The numerical contributions of the team members both deal with convergence, stability and efficiency issues, and with visualization questions.
The contributions of the team can be divided into three main axes and methodologies, which are non-exclusive since many researchers contribute to several of them : Mathematical modelling for physics and engineering, Mathematical Biology, Numerical methods and Scientific Computing.
Research themes (detailed description)
↓ Mathematical modelling for physics and engineering
The research related to Mathematical modelling for physics and engineering performed in the MMCS team covers a large spectrum of problems : mechanics of structures, fluid mechanices, gas dynamics, and many interaction problems where several states of matter appear. Problems concerned with Image and Discrete Geometry are also studied, with standard physics problems. The contributions with their domains of applications can be presented as follows :

↓ Mathematical Biology
The research on mathematical biology made by the MMCS team is strongly motivated by modelling. There are many collaborations with biologists and medical researchers, and a large spectrum of theoretical tools is covered. There are several natural links with the other research axes of the team. A substantial part of the mathematical biology research is associated with the Inria Dracula team.

↓ Numerical methods and Scientific Computing
The analysis and development of numerical methods, as well as developping efficient codes, belong to the traditional research axes of the MMCS team. This theme is separated from the others due to the diversity of tools, however most of the works are associated with modelling studies.
Finite volume methods : schemes for the simulation of flows (Navier-Stokes, Euler, Baer-Nunziato, shallow waters) or diffusion equations (with coupling between domains of different dimensions) (S. Delcourte, D. Le Roux, M. Marion, G. Panasenko, K. Saleh, M.-C. Viallon)
Galerkin methods : schemes for the simulation of contact, multi-cracking, plastic deformation phenomena, for the simulation of shallow water folows, for heterogeneous coupling of Darcy-Stokes type, for the propagation of elastic, acoustic or electromagnetic waves, adaptive schemes (A. Agouzal, M. Bergot, N. Debit, S. Delcourte, D. Le Roux, A. Petrov, Y. Renard)
Spectral methods
