Stability estimates of the mortar finite element method for 3-dimensional problems

By D. Braess, W. Dahmen and Aachen Technische Hochschule (Germany). Inst. fuer Geometrie und Praktische Mathematik

Abstract

This paper is concerned with the mortar finite element method for three spatial variables. The two main issues are the proof of the LBB condition based on appropriate choices of Lagrange multipliers and optimal efficiency of corresponding multigrid schemes for the whole coupled systems of equations. The implementation of the smoothing procedures also differs from that one used in the 2-dimensional case.
