Fundamental Data Structures for Matrix-Free Finite Elements on Hybrid Tetrahedral Grids
Nils Kohl, Daniel Bauer, Fabian Böhm +1
This paper presents efficient data structures for the implementation of matrix-free finite element methods on block-structured, hybrid tetrahedral grids. It provides a complete cat…
Model-Based Performance Analysis of the HyTeG Finite Element Framework
Dominik Thönnes, Ulrich Rüde
In this work, we present how code generation techniques significantly improve the performance of the computational kernels in the HyTeG software framework. This HPC framework combi…
Scalable Flow Simulations with the Lattice Boltzmann Method
Markus Holzer, Jayesh Badwaik, Radim Vavrik +7
The primary goal of the EuroHPC JU project SCALABLE is to develop an industrial Lattice Boltzmann Method (LBM)-based computational fluid dynamics (CFD) solver capable of exploiting…
Efficiency and scalability of fully-resolved fluid-particle simulations on heterogeneous CPU-GPU architectures
Samuel Kemmler, Christoph Rettinger, Ulrich Rüde +2
Current supercomputers often have a heterogeneous architecture using both CPUs and GPUs. At the same time, numerical simulation tasks frequently involve multiphysics scenarios whos…
Particle-resolved simulation of antidunes in free-surface flows
Christoph Schwarzmeier, Christoph Rettinger, Samuel Kemmler +5
The interaction of supercritical turbulent flows with granular sediment beds is challenging to study both experimentally and numerically; this challenging task has hampered the adv…
