A P-Adaptive Hybridizable Discontinuous Galerkin Spectral Element Method for Electrostatic Particle-in-Cell Simulations
Tobias Ott, Stephen Copplestone, Marcel Pfeiffer
This paper presents a p-adaptive high-order hybridizable discontinuous Galerkin spectral element method (HDG-SEM) for solving the Poisson equation in electrostatic plasma simulatio…
A framework for high-fidelity particle tracking on massively parallel systems
Patrick Kopper, Anna Schwarz, Stephen M. Copplestone +3
Particle-laden flows occur in a wide range of disciplines, from atmospheric flows to renewable energy to turbomachinery. They generally pose a challenging environment for the numer…
Hybrid Parallelization of Euler-Lagrange Simulations Based on MPI-3 Shared Memory
Patrick Kopper, Stephen Copplestone, Marcel Pfeiffer +3
The use of Euler-Lagrange methods on unstructured grids extends their application area to more versatile setups. However, the lack of a regular topology limits the scalability of d…
A Load Balance Strategy for Hybrid Particle-Mesh Methods
P. Ortwein, T. Binder, S. Copplestone +5
We present a load balancing strategy for hybrid particle-mesh methods that is based on domain decomposition and element-local time measurement. This new strategy is compared to our…
Load balancing strategies for the DSMC simulation of hypersonic flows using HPC
T. Binder, S. Copplestone, A. Mirza +6
In the context of the validation of PICLas, a kinetic particle suite for the simulation of rarefied, non-equilibrium plasma flows, the biased hypersonic nitrogen flow around a blun…
