On the analysis of block smoothers for saddle point problems
Lorenz John, Ulrich Rüde, Barbara Wohlmuth +1
In this article, we discuss several classes of Uzawa smoothers for the application in multigrid methods in the context of saddle point problems. Beside commonly used variants, such…
A two-scale approach for efficient on-the-fly operator assembly in massively parallel high performance multigrid codes
Simon Bauer, Marcus Mohr, Ulrich Rüde +3
Matrix-free finite element implementations of massively parallel geometric multigrid save memory and are often significantly faster than implementations using classical sparse matr…
Highly sparse surface couplings for subdomain-wise isoviscous Stokes finite element discretizations
Markus Huber, Ulrich Rüde, Christian Waluga +1
The Stokes system with constant viscosity can be cast into different formulations by exploiting the incompressibility constraint. For instance the strain in the weak formulation ca…
