The TELEMAC-MASCARET modelling system
The TELEMAC-MASCARET system is a powerful integrated modeling tool for use in the field of free-surface flows. Having been used in the context of very many studies throughout the world (several hundred to date), it has become one of the major standards in its field.
The various simulation modules use high-capacity algorithms based on the finite-element method. Space is discretised in the form of an unstructured grid of triangular elements, which means that it can be refined particularly in areas of special interest. This avoids the need for systematic use of embedded models, as is the case with the finite-difference method.

All the numerical algorithms are gathered into a single library (BIEF) that is shared by all the simulation modules. This makes for consistency throughout the TELEMAC-MASCARET system.
The pre- and post-processing tools are particularly powerful and user-friendly. Most of them are based on the use of Ilog/Views libraries and offer a range of extremely sophisticated functions. The grid can be generated with the generator embedded in the TELEMAC-MASCARET system (MATISSE module, now deprecated) or by others (Blue-Kenue, Janet).

TELEMAC-MASCARET has numerous applications in both river and maritime hydraulics.
The system was developed by the Laboratoire National d'Hydraulique, a department of Electricité de France's Research and Development Division. It is now available as open source, and is developped by the Open Telemac-Mascaret Consortium.
The various modules of the TELEMAC-MASCARET system run under:
Windows (NT, XP, Vista, Win7)
Linux (Ubuntu, Fedora, Redhat, OpenSUSE, Debian)
Supercalculators (Cray, Fujitsu, IBM, …)
