Abstract
Streamer discharges are fast ionisation fronts that are of crucial importance to many academic and industrial fields, including: understanding of geophysical processes, gaseous breakdown, surface treatment technology, bio-decontamination, air cleaning, and pulsed power system design. The growing capabilities of modern computers allow streamers to be simulated on desktop computers. However, it is far from a trivial task. In this work, we demonstrate a parallelised, adaptive-mesh enabled code developed using FEniCS in python. We show that the platform is capable of simulating streamer propagation in pure gas and across gas-solid interfaces, with the inclusion of complex photoionisation processes, while simultaneously being user-friendly yet comparably fast to previously published codes. We further demonstrate that FEniCS is a highly suitable alternative, by showing excellent agreement between our simulated results, results from published custom codes, and results from popular commercial applications.
