Grid Orientation Effect and MultiPoint Flux Approximation

Résumé

Some cases of nonlinear coupling between a diffusion equation, related to the computation of a pressure field within a porous medium, and a convection equation, related to the conservation of a species, lead to the apparition of the so-called grid orientation effect. We propose in this paper a new procedure to eliminate this Grid Orientation Effect, only based on the modification of the stencil of the discrete version of the convection equation. Numerical results show the efficiency and the accuracy of the method.
