### ns2ddv

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

The ns2ddv 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 [42] . The current version of the ns2ddv code is being developped around the GetFem++ and the Bamg softwares. It allows in particular mesh refinement strategies so that very relevant simulations can be reached (As the falling droplet with very high density ratios, see for example [32] ).
