“…Examples are found in . A more exhaustive list of contributions to the development of the MFD method can also be found in the two review works [33] and [34]. Other discretization frameworks related to general meshes include the polygonal/polyhedral finite element method (PFEM) [35,36], the finite volume methods [37], the hybrid high-order (HHO) method [38,39], the discontinuous Galerkin (DG) method [40,41], the hybridized discontinuous Galerkin (HDG) method [42], the weak Galerkin (wG) method [43], the virtual element method (VEM) [44] and its connections with the PFEM [45], and the more recent Discontinuous Skeletal Gradient Discretization (DSGD) [46].…”
