Direct simulation of liquid-gas-solid flow with a free surface lattice Boltzmann method
Simon Bogner, Jens Harting, Ulrich Rüde
Direct numerical simulation of liquid-gas-solid flows is uncommon due to the considerable computational cost. As the grid spacing is determined by the smallest involved length scal…
A stencil scaling approach for accelerating matrix-free finite element implementations
Simon Bauer, Daniel Drzisga, Marcus Mohr +3
We present a novel approach to fast on-the-fly low order finite element assembly for scalar elliptic partial differential equations of Darcy type with variable coefficients optimiz…
A Scalable Multiphysics Algorithm for Massively Parallel Direct Numerical Simulations of Electrophoresis
Dominik Bartuschat, Ulrich Rüde
In this article we introduce a novel coupled algorithm for massively parallel direct numerical simulations of electrophoresis in microfluidic flows. This multiphysics algorithm emp…
Extreme-Scale Block-Structured Adaptive Mesh Refinement
Florian Schornbaum, Ulrich Rüde
In this article, we present a novel approach for block-structured adaptive mesh refinement (AMR) that is suitable for extreme-scale parallelism. All data structures are designed su…
A comparative study of fluid-particle coupling methods for fully resolved lattice Boltzmann simulations
Christoph Rettinger, Ulrich Rüde
The direct numerical simulation of particulate systems offers a unique approach to study the dynamics of fluid-solid suspensions by fully resolving the submerged particles and with…
