Discrete-duality finite volume method for second order elliptic problems
Résumé
This paper deals with applications of the "Discrete-Duality Finite Volume" approach to a variety of elliptic problems. This is a new finite volume method, based on the derivation of discrete operators obeying a Discrete-Duality principle. An appropriate choice of the degrees of freedom allows one to use arbitrary meshes. We show that the method is naturally related to finite and mixed finite element methods.
