Code Generation and Performance Engineering for Matrix-Free Finite Element Methods on Hybrid Tetrahedral Grids
Fabian Böhm, Daniel Bauer, Nils Kohl +5
This paper introduces a code generator designed for node-level optimized, extreme-scalable, matrix-free finite element operators on hybrid tetrahedral grids. It optimizes the local…
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…
Comparison of refilling schemes in the free-surface lattice Boltzmann method
Christoph Schwarzmeier, Ulrich Rüde
Simulating mobile liquid-gas interfaces with the free-surface lattice Boltzmann method (FSLBM) requires frequent re-initialization of fluid flow information in computational cells…
A decoupled numerical method for two-phase flows of different densities and viscosities in superposed fluid and porous layers
Yali Gao, Daozhi Han, Xiaoming He +1
In this article we consider the numerical modeling and simulation via the phase field approach of two-phase flows of different densities and viscosities in superposed fluid and por…
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…
