Smooth Finite Elements Based on Powell-Sabin Triangle Split Triangles

by Peter Alfeld and Larry Schumaker.

Advances in Comp. Math., to appear.

Abstract

Macro elements of smoothness Cr are constructed on Powell Sabin triangle splits for all r >= 0. In contrast to earlier constructions, our elements depend only on natural derivative information.
