Code Saturne

code_saturne is a free and open-source computational fluid dynamics (CFD) solver developed by the research and development division of Électricité de France (EDF). Released under the GNU General Public License since 2007, it is based on a co-located finite volume method and can simulate incompressible or low-Mach number dilatable flows, with or without turbulence and heat transfer.

The software is integrated into the SALOME platform through the salome_cfd distribution and can be coupled with the solid thermal code SYRTHES and the structural mechanics code code_aster, both also developed by EDF under free software licences.

Its two-phase extension, Neptune_CFD, co-developed by EDF and the CEA, handles two-phase flows such as water-steam and water-air mixtures.
