Symmetric Point Structure of Superconvergence for Cubic Triangular Elements—A Consultation with Zhu

Author(s)

Abstract

Superconvergence structures for rectangular and triangular finite elements are summarized. Two debatable issues in Zhu's paper [18] are discussed. A superclose polynomial to cubic triangular finite element is constructed by area coordinate.

Keywords:

Cubic triangular element Superconvergence Symmetric points.
