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…
Research and Education in Computational Science and Engineering
Ulrich Rüde, Karen Willcox, Lois Curfman McInnes +30
Over the past two decades the field of computational science and engineering (CSE) has penetrated both basic and applied research in academia, industry, and laboratories to advance…
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…
Microswimming with inertia
Jayant Pande, Kristina Pickl, Oleg Trosman +2
Microswimmers, especially in theoretical treatments, are generally taken to be completely inertia-free, since inertial effects on their motion are typically small and assuming thei…
