waLBerla: A block-structured high-performance framework for multiphysics simulations
Martin Bauer, Sebastian Eibl, Christian Godenschwager +8
Programming current supercomputers efficiently is a challenging task. Multiple levels of parallelism on the core, on the compute node, and between nodes need to be exploited to mak…
On numerical solution of full rank linear systems
A. Dumitrasc, Ph. Leleux, C. Popa +2
Matrices can be augmented by adding additional columns such that a partitioning of the matrix in blocks of rows defines mutually orthogonal subspaces. This augmented system can the…
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…
A Modular and Extensible Software Architecture for Particle Dynamics
Sebastian Eibl, Ulrich Rüde
Creating a highly parallel and flexible discrete element software requires an interdisciplinary approach, where expertise from different disciplines is combined. On the one hand do…
Validation and calibration of coupled porous-medium and free-flow problems using pore-scale resolved models
Iryna Rybak, Christoph Schwarzmeier, Elissa Eggenweiler +1
The correct choice of interface conditions and effective parameters for coupled macroscale free-flow and porous-medium models is crucial for a complete mathematical description of…
Computational Study of Ultrathin CNT Films with the Scalable Mesoscopic Distinct Element Method
Igor Ostanin, Traian Dumitrică, Sebastian Eibl +1
In this work we present a computational study of the small strain mechanics of freestanding ultrathin CNT films under in-plane loading. The numerical modeling of the mechanics of r…
