Astrophysics on GPUs: introducing AGILE 1.0
Oliver Porth, Adrian Kelly, Olaf Willocx +10
We present AGILE, a GPU-enabled adaptive mesh refinement (AMR) framework for the solution of (near-) conservation laws which occur in astro- and solar-physical applications. AGILE…
foap4: Adaptive mesh refinement with OpenACC/OpenMP, MPI, and p4est
Jannis Teunissen, Héctor R. Olivares Sánchez, Jesse Vos +10
GPUs and other accelerators are increasingly used for scientific computing. We want to add GPU support to existing parallel adaptive mesh refinement (AMR) codes written in Fortran.…
Stochastic simulation of partial discharge inception
Jannis Teunissen, Yuting Gao
We present a Monte Carlo method for simulating the inception of electric discharges in gases. The input consists of an unstructured grid containing the electrostatic field. The out…
Data-driven reduced modeling of streamer discharges in air
Jannis Teunissen, Alejandro Malagón-Romero
We present a computational framework for simulating filamentary electric discharges, in which channels are represented as conducting cylindrical segments. The framework requires a…
Positive streamer discharge simulations in humid air: uncertainty in input data and sensitivity analysis
Baohong Guo, Hemaditya Malla, Alejandro Malagon-Romero +1
We study how the choice of input data affects simulations of positive streamers in humid air, focusing on H2O cross sections, photoionization models, and chemistry sets. Simulation…
Measurement of the electric field distribution in streamer discharges
Yihao Guo, Anne Limburg, Jesse Laarman +2
Using electric field induced second harmonic generation (E-FISH), we performed direction-resolved absolute electric field measurements on single-channel streamer discharges in 70 m…
A model comparison of 2D Cartesian and 2D axisymmetric models for positive streamer discharges in air
Zhen Wang, Anbang Sun, Jannis Teunissen
Simulating streamer discharges in 3D can computationally be very expensive, which is why 2D Cartesian simulations are sometimes used instead, especially when dealing with complex g…
A comprehensive comparison of relativistic particle integrators
Bart Ripperda, Fabio Bacchini, Jannis Teunissen +5
We compare relativistic particle integrators commonly used in plasma physics showing several test cases relevant for astrophysics. Three explicit particle pushers are considered, n…
