Superconvergence of tensor-product quadratic pentahedral elements for variable coefficient elliptic equations (English)
0 references
The author solves a Dirichlet problem attached to a 3D linear elliptic equation in divergence form, for a rectangular block domain. He claims a max norm result for the derivatives of its tensor-product quadratic pentahedral finite elements solution. Unfortunately the paper contains some unclear or incomplete statements.
