Superconvergence by M-decompositions. Part III: Construction of three-dimensional finite elements∗
Revised: 20 March 2016
Accepted: 31 March 2016
We apply the concept of an M-decomposition in the framework of steady-state diffusion problems to construct local spaces defining superconvergent hybridizable discontinuous Galerkin methods as well as their companion sandwiching mixed methods in ℝ3 with tetrahedral, pyramidal, prismatic, and hexahedral elements.
