**JADIM**

JADIM is a code which permits to solve the incompressible, unsteady and 3-D Navier-Stokes equations :

and the advection-diffusion of a passive scalar on a orthogonal mesh:

The equations are written in primitive variables (velocity-pressure) and are solved with the finite volume method. Schemas used give to the code a two order precision in time and in space thanks to three order Runge-Kutta advancement schema and thanks to a semi-implicit Crank-Nicholson method concerning the diffusive terms resolution.

JADIM also
permits :

* a LES simulation using a "mixed-dynamic" model.

* a diphasic VOF calculation on a fixed mesh.

* a lagrangian particles following.
