The 14-parameter nonconforming tetrahedral finite element for fourth order elliptic equations. (English) Zbl 1208.35038
Summary: This paper presents the 14-parameter nonconforming tetrahedral element for the discretization of fourth order elliptic partial differential operators in three spatial dimensions. The newly constructed element is proved to be convergent for a model biharmonic equation in three dimensions.
