Numerical Zoom and the Schwarz Algorithm

Abstract

We investigate Schwarz’ domain decomposition algorithm as a tool for numerical zoom and compare it with the Subspace Correction Method. Quadrature error is investigated and the convergence of Schwarz’ algorithm is sketched for non matching grids. The methods are also compared numerically.
