Benchmark 3D: CeVeFE-DDFV, a discrete duality scheme with cell/vertex/face plus edge unknowns

The method that we investigate in this contribution was proposed by Y. Coudiére and F. Hubert in [1] as a three-dimensional (3D) extension of the finite volume scheme previously studied by F. Hermeline in [4] and K. Domelevo and P. Omn'es in [3]. This method belongs to the family of Discrete Duality Finite Volume (DDFV) methods, which can naturally handle anisotropic or non-linear problems on general distorted meshes.
