[Un nouveau schéma préservant lʼasymptotique avec le principe du maximum pour le modèle sur maillages quelconques]
Dans cette Note, nous montrons quʼun nouveau schéma introduit dans Buet et al. (2011) [5] pour le modèle à deux moments non linéaire de lʼéquation de transport et qui est compatible avec la limite de diffusion (schéma AP) sur maillage quelconque vérifie aussi le principe du maximum. Lʼidée consiste à réécrire le modèle comme un système de la dynamique des gaz, puis à utiliser un schéma Eulerien nodal, dérivé dʼun schéma Lagrange + projection couplé à une extension multidimensionnelle, developpée dans Buet et al. (2012) [6], de la méthode de Jin et Levermore (1996) [9] pour lʼéquation de la chaleur hyperbolique. Après la présentation du schéma on donne les preuves dʼentropie et de principe du maximum. Pour finir on présente des résultats numériques pour des maillages déformés triangulaires et quadrangulaires qui montrent notamment lʼordre deux dans le régime de diffusion.
In this Note, we show that a recent scheme introduced by Buet et al. (2011) [5] for the nonlinear two moments model of linear transport and which captures correctly the diffusion limit on distorded meshes (AP scheme) also possesses the maximum principle. The main idea of the design of this scheme is to rewrite the model as a gas dynamics model and to use an Eulerian scheme, derived from a Lagrange + remap scheme. To obtain the AP property we use the multidimensional extension, developed by Buet et al. (2012) [6], of the Jin and Levermore (1996) procedure [9] for the hyperbolic heat equation. We will show that this scheme is entropic which ensures the maximum principle of the model. More we present some numerical results, on distorted quadrangular and triangular meshes which show that the scheme is second order in the diffusive regime.
