Contract with CEA Bruyères-Le-Châtel: Determination of the numerical diffusion in a Lagrange-Projection type scheme with a slope limiter, using the associated equivalent equation

Participant : Nicolas Crouseilles.

Other participants (outside IPSO) are D. Bouche, J.P. Braeunig, Ch. Steiner, M. Mehrenberger. The main goal of this contract is to determine equivalent equations for standard numerical schemes dedicated to advection equations. In particular, the first term arising in these equivalent equation concerns the numerical diffusion. These computations enable to quantify in a analytical way the numerical diffusion.
