Cancellation exponent and multifractal structure in two-dimensional magnetohydrodynamics: direct numerical simulations and Lagrangian averaged modeling

, 2005
We present direct numerical simulations and Lagrangian averaged (also known as alpha-model) simulations of forced and free decaying magnetohydrodynamic turbulence in two dimensions.

Evolution of Magnetospheric Boundary Layers Under the 10 May 2024 ICME Impact

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract On 10 May 2024, an interplanetary coronal mass ejection‐driven shock impacted the dayside magnetopause, compressing it to ∼5 RE. A northward interplanetary magnetic field suppressed dayside reconnection and allowed a clear investigation of the magnetosphere response.

Nonlinear Gyrokinetic Simulation of the Magnetosphere‐Ionosphere Feedback Coupling

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract A nonlinear gyrokinetic simulation is applied to the magnetosphere‐ionosphere (M‐I) coupling system to investigate spontaneous growth of auroral structures and electron acceleration self‐consistently. Perturbations of electron density, potential and field‐aligned current in the auroral ionosphere develop through the feedback instability ...

Asymmetrically Distributed Kelvin‐Helmholtz Instability at Venusian Magnetosphere

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract The asymmetric distribution of Kelvin‐Helmholtz (KH) instability at Venusian ionopause is investigated using a multifluid model. Results show that KH instability distributes asymmetrically, preferentially developing in the −E (anti‐parallel to the interplanetary electric field) hemisphere.

Simulating the Photospheric to Coronal Plasma Using Magnetohydrodynamic Characteristics. I. Data-driven Boundary Conditions

The Astrophysical Journal Supplement Series
We develop a general description of how information propagates through a magnetohydrodynamic (MHD) system based on the method of characteristics and use that to formulate numerical boundary conditions that are intrinsically consistent with the MHD ...

Parallel grid library for rapid and flexible simulation development

, 2012
We present an easy to use and flexible grid library for developing highly scalable parallel simulations. The distributed cartesian cell-refinable grid (dccrg) supports adaptive mesh refinement and allows an arbitrary C++ class to be used as cell data ...

Mars' Ionospheric Response to the Onset and Early Phase of 20 May 2024 Solar Flare

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Solar extreme ultraviolet (EUV, 10–100 nm) and X‐ray (<10 nm) photons are the primary ionization source for the dayside Mars ionosphere. Their fluxes, especially at short wavelengths, increase significantly during solar flares. Among the series of solar flares and solar storms encountered by Earth and Mars in May 2024, one of the strongest ...

Formation of Fine Structures in Incompressible Hall Magnetohydrodynamic Turbulence Simulations

Plasma
Hall magnetohydrodynamic simulations are often carried out to study the subjects of instabilities and turbulence of space and nuclear fusion plasmas in which sub-ion-scale effects are important.

New numerical method for mechanics of continuous media

Computer Assisted Methods in Engineering and Science, 2023
A new, original numerical method of free particles, for mechanics of continuous media, has been developed. The free particle hydrocodes (HEFP), based on this method, are the powerful tools that can be used to simulate, in the sense of computational ...
