| Abstract: | The relationships between a general family of nodal schemes J.P. Hennart, SIAM J. Sci. Stat. Comput. 3 , 264 (1986)] and primal nonconforming as well as mixed-hybrid finite element formulations are explored in this paper. It is shown in particular that the nodal schemes proposed are quite natural extensions in rectangular geometry of the Raviart-Thomas-Nédélec mixed-hybrid finite elements. This paper is a revised and extended version with new numerical results of part of a previous research report J.P. Hennart, Rapports de Recherche INRIA Vol. 386 (1985)]. © 1993 John Wiley & Sons, Inc. |
