A Multipoint Flux Mixed Finite Element Method on Hexahedra

We develop a mixed finite element method for elliptic problems on hexahedral grids that reduces to cell-centered finite differences. The paper is an extension of our earlier paper for quadrilateral and simplicial grids [SIAM J. Numer. Anal., Vol. 55, pp. 2082
