Superconvergence analysis of Wilson element on anisotropic meshes
- 41 Downloads
The Wilson finite element method is considered to solve a class of two-dimensional second order elliptic boundary value problems. By using of the particular structure of the element and some new techniques, we obtain the superclose and global superconvergence on anisotropic meshes. Numerical example is also given to confirm our theoretical analysis.
