Code-Saturne

Code_Saturne is an open-source general-purpose Computational Fluid Dynamics (CFD) software developed by the French nuclear power group EDF, with wide applications in the energy sector, particularly in nuclear power.

By solving the Navier-Stokes equations, Code_Saturne can handle 2D/3D, steady/unsteady, laminar/turbulent (with various turbulence models), incompressible/weakly compressible, and isothermal/non-isothermal calculations. The software features good parallelism, supports general thermal, fluid, and environmental analysis, and includes multiple modules tailored for the energy industry.
