ORTHOGONALITY CORRECTION TECHNIQUE IN SUPERCONVERGENCE ANALYSIS

Chuanmiao Chen, C. Chen

Abstract

Abstract. A technique of orthogonality correction in an element is introduced and applied to superconvergence analysis in finite element method. Ultracon-vergence results for rectangular elements of odd degree n ≥ 3 are derived in the case of variable coefficients. Key Words. Finite elements, rectangular element, orthogonality correction, superconvergence and ultraconvergence. 1.
