Finite volume box schemes and mixed methods
Finite Volume Box Schemes and Mixed Methods
We present the numerical analysis on the Poisson problem of two mixed Petrov-Galerkin finite volume schemes for equations in divergence form . The first scheme, which has been introduced in [CITE], is a generalization in two dimensions of Keller's box-scheme. The second scheme is the dual of the first one, and is a cell-centered scheme for and the flux . For the first scheme, the two trial finite element spaces are the nonconforming space of Crouzeix-Raviart for the primal unknown and...
