Abstract
- Ciarlet‐Raviart's scheme is a finite element method for solving the mixed formulation of the biharmonic equation. So far, there has been no superconvergence for the vorticity from this method if a general rectangular mesh is used. In this article, we deal with the biquadratic elements under the uniform rectangular mesh and prove for the first time a superconvergence for the vorticity. © 2002 Wiley Periodicals, Inc.
