TL;DR: This study considers multiphysics applications from algorithmic and architectural perspectives, where “algorithmic” includes both mathematical analysis and computational complexity, and “architectural’ includes both software and hardware environments.
Journal ArticleDOI
A high resolution wave propagation scheme for ideal Two-Fluid plasma equations
TL;DR: The ideal Two-Fluid model is more general than the often used magnetohydrodynamic model and takes into account electron inertia effects, charge separation and the full electromagnetic field equations and allows for separate electron and ion motion.
Journal ArticleDOI
Discontinuous Galerkin algorithms for fully kinetic plasmas
TL;DR: A new algorithm for the discretization of the non-relativistic Vlasov–Maxwell system of equations for the study of plasmas in the kinetic regime is presented, and a high order accurate solution for the plasma's distribution function is obtained.
Journal ArticleDOI
Comparison of multi-fluid moment models with particle-in-cell simulations of collisionless magnetic reconnection
TL;DR: In this article, an extensible multi-fluid moment model is proposed for collisionless magnetic reconnection, which evolves full Maxwell equations and simultaneously moments of the Vlasov-Maxwell equation for each species in the plasma.
Journal ArticleDOI
Extended MHD Modelling with the Ten-Moment Equations
TL;DR: In this article, high-order moment fluid equations for simulation of plasmas are presented, which are a two-fluid model in which time dependent equations are used to advance the pressure tensor.
