Abstract

Mathematics Mathematics, Applied Physical Sciences Science & Technology
In this article, we implement the mortar spectral element method for the Stokes problem on a domain within corners. We consider the Strang and Fix algorithm, which permits to enlarge the discrete space of the velocity by the first singular function. The usefulness of this method is confirmed by the numerical results presented here.
