Smooth Finite Elements Based on Powell-Sabin Triangle Split Triangles

by Peter Alfeld and Larry Schumaker.

Advances in Comp. Math., to appear.


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.
