Preconditioners for nonconforming domain decomposition methods

摘要

In this article we briefly discuss two preconditioner techniques, the Neumann–Neumann-preconditioner and the Dirichlet–Neumann-preconditioner, for nonconforming domain decomposition methods. We will show with some examples that the numerical results obtained with nonconforming multidomain techniques are qualitatively equivalent to the results obtained on an unique domain.
