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…
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…
foap4: Adaptive mesh refinement with OpenACC, MPI, and p4est
Jannis Teunissen, Héctor R. Olivares Sánchez, Jesse Vos +10
GPUs and other accelerators are increasingly used for scientific computing. In the future, we want to add GPU support to parallel adaptive mesh refinement (AMR) codes written in Fo…
Data-driven reduced modeling of streamer discharges in air
Jannis Teunissen, Alejandro Malagón-Romero, 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…
