Ocean Model SYMPHONIE:

       
 SYMPHONIE is basically a three-dimensional primitive equation ocean model. The three components of the current, free surface elevation, temperature and salinity are computed on a C grid, using an energy conserving finite difference method (Marsaleix et al, 2008). A generalized vertical coordinate and a curvilinear horizontal coordinate are used. The turbulence closure is achieved through a prognostic equation for the turbulent kinetic energy and a diagnostic equation for the mixing and dissipation length scales. A leap frog scheme is used for the time stepping. Calculus costs are limited thanks to a time splitting technique that permits to compute the vertical shear of the current and its depth-averaged components separately with appropriate time steps. Radiation conditions combined to restoring terms to the large-scale circulation are applied at the open boundaries (Marsaleix et al, 2006).
       A Non-Hydrostatic version of the SYMPHONIE code is now available. A prognostic equation for the vertical momentum has been implemented resulting in the inversion of a classical Poisson equation for the non-hydrostatic component of the pressure.
