• Simulation platform NUM3SIS

    NUM3SIS is a multidisciplinary simulation platform developed jointly by Opale, Nachos and Tosca teams and used for prototyping numerical methods. It is based on modern software engineering techniques, such as visual programming or plugin system to facilitate and speed up developments.

    More details can be found at NUM3SIS web site

    It contains presently plugins for the following fields:

    • Compressible flows (Reynolds-averaged Navier-Stokes equations)
    • Electromagnetics (space-time Maxwell equations)
    • Pedestrian and automotive traffic flows (macroscopic continuous models)
