Realistic magnetohydrodynamical simulation of solar local supergranulation [PDF]

open access: yesPhysica Scripta, 2010
Three-dimensional numerical simulations of solar surface magnetoconvection using realistic model physics are conducted. The thermal structure of convective motions into the upper radiative layers of the photosphere, the main scales of convective cells and the penetration depths of convection are investigated.

Modeling Kinetic Reconnection Onset in Global Magnetospheric Simulations

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 9, September 2026.
Abstract We investigate the onset of magnetic reconnection in Earth's magnetotail using a coupled magnetohydrodynamic with embedded particle‐in‐cell (MHD‐EPIC) model, which self‐consistently links global magnetospheric dynamics to electron‐scale kinetic processes. Unlike standalone kinetic simulations with idealized boundary conditions, reconnection in

Well-Posedness for a Magnetohydrodynamical Model with Intrinsic Magnetisation

open access: yes
Ferromagnetic magnetohydrodynamics concerns the study of conducting fluids with intrinsic magnetisation under the influence of a magnetic field. It is a generalisation of the magnetohydrodynamical equations and takes into account the dynamics of the ...

Particle Acceleration and Magnetic Field Amplification by Relativistic Shocks in Inhomogeneous Media

open access: yesThe Astrophysical Journal Letters
Particle acceleration and magnetic field amplification in relativistic shocks propagating in inhomogeneous media are investigated by three-dimensional magnetohydrodynamical (MHD) simulations and test-particle simulations.

Michigan Geospace Model With Ensemble Forecasting and Particle Filtering: Modeling the May 2024 Extreme Storm

open access: yesSpace Weather, Volume 24, Issue 9, September 2026.
Abstract This paper introduces an updated version of the University of Michigan Geospace model. The Geospace model has been used for operational forecasting at the Space Weather Modeling Center of the National Oceanic and Atmospheric Agency since 2016 with regular updates. The current operational version, Geospace V2, was launched in 2021 and is driven

Relativistic jets: Physics and simulations

open access: yes, 2010
Jets are one of the more dramatic and visible manifestations of black hole accretion. It is becoming increasingly accepted that magnetic fields underlie the mechanism behind the launching of relativistic jets.

How can exploratory learning with games and simulations within the curriculum be most effectively evaluated? [PDF]

open access: yes, 2006
There have been few attempts to introduce frameworks that can help support tutors evaluate educational games and simulations that can be most effective in their particular learning context and subject area.

Fluctuation Dynamos in Supersonic Turbulence at Pm ≳ 1

open access: yesThe Astrophysical Journal
Fluctuation dynamos provide a robust mechanism for amplifying weak seed magnetic fields in turbulent astrophysical plasmas. However, their behaviour in the highly compressible regimes characteristic of the interstellar medium remains incompletely ...
