The code FluidBox is a non-specialized platform for compressible fluids flows simulation. The targeted fluids can be of very different nature and are characterized by their state. A version of this software is at present downloadable under open source license CeCILL-C in the INRIA’s GForge (https: // to gforge.inria.fr / projects / fluidbox/). Possible applications’ domains concern the aerodynamics, the multi-fluid flows and multi-phases, turbulent. This code has been developed for more than ten years and requires henceforth a more professional management if we want to have a more important transfer. The purpose of this project, which will end in a platform of calculation named RealFluids and whose code FluidBox constitutes a part of the scientific base, is to create a professional version of FluidBox by including software management tools, better definition of input/output modules, a better management of different mesh formats, a human-machine interface, a base of not-regression, almost absent things at present. It will thus be a question of facilitating a better management of the code (creation and validation of not-regressive tests, portability of the code, the facilitation of management of modules, to allow easier encapsulation of the code in the other physical or mathematical models, the numerical stability and the control of floating-point errors, etc.), to envisage the distribution of a new open source version (the choice of the license will be made at the right moment) but also a transfer towards one or more SMEs. FluidBox interested, indeed, in past the company Glaizer Innovation and more recently the company AXS and Valeol, the latter situated in the suburb of Bordeaux and making pales of wind turbines.
