[Une méthode multi-domaines pour résoudre numériquement des problèmes elliptiques multi-échelles]
Dans cette Note nous présentons une famille de méthodes itératives pour résoudre numériquement des problèmes elliptiques du deuxième ordre à données multi-échelles utilisant plusieurs niveaux de grilles. Ces méthodes sont basées sur l'introduction d'un multiplicateur de Lagrange pour imposer la continuité de la solution et de ses flux à travers les interfaces. Ces méthodes peuvent être interprétées comme des méthodes de décomposition de domaines avec recouvrement total, de type mortier, pour résoudre numériquement des problèmes elliptiques multi-échelles.
In this paper we present a family of iterative methods to solve numerically second order elliptic problems with multi-scale data using multiple levels of grids. These methods are based upon the introduction of a Lagrange multiplier to enforce the continuity of the solution and its fluxes across interfaces. This family of methods can be interpreted as a mortar element method with complete overlapping domain decomposition for solving numerically multi-scale elliptic problems.
