Participants : Caterina Calgaro [ correspondant ] , Emmanuel Creusé, Thierry Goudon, Emile Chane-Kane.

The NSVarDens code is based on a hybrid method coupling FV and FE approaches for solving the variable density Navier-Stokes equation in dimension 2. This original approach for variable density flows is described in [10] . The code, with a current version in Matlab, is still in a development phase, but simulations of the Rayleigh-Taylor instabilities prove the efficiency of the code. An optimized version will be produced soon and it will be completed by mesh refinements strategy.
