A quantitative performance analysis for Stokes solvers at the extreme scale
Björn Gmeiner, Markus Huber, Lorenz John +2
This article presents a systematic quantitative performance analysis for large finite element computations on extreme scale computing systems. Three parallel iterative solvers for…
Pore-scale lattice Boltzmann simulation of laminar and turbulent flow through a sphere pack
Ehsan Fattahia, Christian Waluga, Barbara Wohlmuth +3
The lattice Boltzmann method can be used to simulate flow through porous media with full geometrical resolution. With such a direct numerical simulation, it becomes possible to stu…
Large scale lattice Boltzmann simulation for the coupling of free and porous media flow
Ehsan Fattahi, Christian Waluga, Barbara Wohlmuth +1
In this work, we investigate the interaction of free and porous media flow by large scale lattice Boltzmann simulations. We study the transport phenomena at the porous interface on…
Resilience for Exascale Enabled Multigrid Methods
Markus Huber, Björn Gmeiner, Ulrich Rüde +1
With the increasing number of components and further miniaturization the mean time between faults in supercomputers will decrease. System level fault tolerance techniques are expen…
