The "3D anisotropy Benchmark" (http://www.latp.univ-mrs.fr/latp_numerique/?q=node/4) addresses a three-dimensional anisotropic diffusion problem, which is discretized on general, possibly non-conforming meshes. In most cases, the diffusion tensor is taken to be anisotropic, and at times heterogeneous and/or discontinuous. This paper presents numerical results to this benchmark for a 3D Cell and Vertex centered DDFV scheme. The method applies to very general 3D meshes including non conformal ones. Its princples and construction is presented as well as its implementation for diffusion problems.
