Geoelectric Field Caused by Flux Transfer Events in an Ionosphere-Coupled Vlasiator Simulation
Konstantinos Horaites, Markku Alho, Yann Pfau-Kempf +10
We report on the relationship between flux transfer events (FTEs) at Earth's magnetopause and the geoelectric field that is induced near the FTEs' magnetic footpoints. We study thi…
Load Balancing in Strongly Inhomogeneous Simulations -- a Vlasiator Case Study
Leo Kotipalo, Markus Battarbee, Yann Pfau-Kempf +2
Parallelization is a necessity for large-scale simulations due to the amount of data processed. In this article we investigate different load balancing methods using Vlasiator, a g…
Coalescing MPI communication in 6D Vlasov simulations: solving ghost domains in Vlasiator
Markus Battarbee, Urs Ganse, Yann Pfau-Kempf +3
High-performance computing is used for diverse simulations, some of which parallelize over the Message Passing Interface (MPI) with ease, whilst others may have challenges related…
Sunward Flows in the Magnetosheath Associated with Magnetic Pressure Gradient and Magnetosheath Expansion
H. Madanian, Y. Pfau-Kempf, R. Rice +5
A density structure within the magnetic cloud of an interplanetary coronal mass ejection impacted Earth and caused significant perturbations in plasma boundaries. We describe the e…
Transient Upstream Mesoscale Structures: Drivers of Solar-Quiet Space Weather
Primož KajdiÄ, Xóchitl Blanco-Cano, Lucile Turc +12
In recent years, it has become increasingly clear that space weather disturbances can be triggered by transient upstream mesoscale structures (TUMS), independently of the occurrenc…
