Abstract

En 中文
We develop a method to compute the H-2-conforming finite element approximation to planar fourth order elliptic problems without having to implement C-1 elements. The algorithm consists of replacing the original H-2-conforming scheme with preprocessing and postprocessing steps that require only an H-1-conforming Poisson type solve and an inner Stokes-like problem that again only requires at most H-1-conformity. We then demonstrate the method applied to the Morgan--Scott elements with three numerical examples.
