A hybridization-derived interior penalty Nitsche method for heterogeneous and anisotropic diffusion
Vincent Fontaine
We develop an interior penalty Nitsche finite element formulation for heterogeneous and anisotropic diffusion problems, which is derived from an interior-penalty stabilized Lagrang…

A Unified Transmissibility-Based Interior Penalty DG Method for Heterogeneous and Anisotropic Diffusion
Gregory Etangsale, Vincent Fontaine, Anis Younes
We derive a primal discontinuous Galerkin (DG) formulation for heterogeneous and anisotropic diffusion, obtained by exact algebraic elimination of the skeletal unknown in a compact…
