A massively parallel Eulerian-Lagrangian method for advection-dominated transport in viscous fluids
Nils Kohl, Marcus Mohr, Sebastian Eibl +1
Motivated by challenges in Earth mantle convection, we present a massively parallel implementation of an Eulerian-Lagrangian method for the advection-diffusion equation in the adve…
Stencil scaling for vector-valued PDEs on hybrid grids with applications to generalized Newtonian fluids
Daniel Drzisga, Ulrich Rüde, Barbara Wohlmuth
Matrix-free finite element implementations for large applications provide an attractive alternative to standard sparse matrix data formats due to the significantly reduced memory c…
The Maximum Dissipation Principle in Rigid-Body Dynamics with Purely Inelastic Impacts
Tobias Preclik, Sebastian Eibl, Ulrich Rüde
Formulating a consistent theory for rigid-body dynamics with impacts is an intricate problem. Twenty years ago Stewart published the first consistent theory with purely inelastic i…
Scheduling massively parallel multigrid for multilevel Monte Carlo methods
Björn Gmeiner, Daniel Drzisga, Ulrich Ruede +2
The computational complexity of naive, sampling-based uncertainty quantification for 3D partial differential equations is extremely high. Multilevel approaches, such as multilevel…
Two Computational Models for Simulating the Tumbling Motion of Elongated Particles in Fluids
Dominik Bartuschat, Ellen Fischermeier, Katarina Gustavsson +1
Suspensions with fiber-like particles in the low Reynolds number regime are modeled by two different approaches that both use a Lagrangian representation of individual particles. T…
