Effect of Sediment Form and Form Distribution on Porosity: A Simulation Study Based on the Discrete Element Method
Christoph Rettinger, Ulrich Rüde, Stefan Vollmer +1
Porosity is one of the key properties of dense particle packings like sediment deposits and is influenced by a multitude of grain characteristics such as their size distribution an…
Coupling fully resolved light particles with the Lattice Boltzmann method on adaptively refined grids
Lukas Werner, Christoph Rettinger, Ulrich Rüde
The simulation of geometrically resolved rigid particles in a fluid relies on coupling algorithms to transfer momentum both ways between the particles and the fluid. In this articl…
An efficient four-way coupled lattice Boltzmann - discrete element method for fully resolved simulations of particle-laden flows
Christoph Rettinger, Ulrich Rüde
A four-way coupling scheme for the direct numerical simulation of particle-laden flows is developed and analyzed. It employs a novel adaptive multi-relaxation time lattice Boltzman…
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…
Dynamic Load Balancing Techniques for Particulate Flow Simulations
Christoph Rettinger, Ulrich Rüde
Parallel multiphysics simulations often suffer from load imbalances originating from the applied coupling of algorithms with spatially and temporally varying workloads. It is thus…
A Coupled Lattice Boltzmann Method and Discrete Element Method for Discrete Particle Simulations of Particulate Flows
Christoph Rettinger, Ulrich Rüde
Discrete particle simulations are widely used to study large-scale particulate flows in complex geometries where particle-particle and particle-fluid interactions require an adequa…
