Locating Natural Superconvergent Points of Finite Element Methods in 3D
Keywords:
finite element methods, three-dimensional problems, natural superconvergence, pentahedral elements and tetrahedral elements.Abstract
In [20], we analytically identified natural superconvergent points of function values and gradients for several popular three-dimensional polynomial finite elements via an orthogonal decomposition. This paper focuses on the detailed process for determining the superconvergent points of pentahedral and tetrahedral elements.
