Other Abstract

Hydrodynamics (HD) and Magnetohydrodynamics (MHD) simulation technics have been wildly developed, in the last decade, in order to describe the plasma behavior in a magnetic field related to some kinds of astrophysical system, such as magnetic reconnection in solar eruptions or the interstellar medium, star formation, and accretion flows. As we know, MHD approximation considers the plasmas as a collisionless neutral fluid and focuses on the macro description of dynamic phenomenons. Basically, we have two ways to describe fluids. One of them is Lagrangian method, while the other is Eulerian method. And MHD simulations usually belong to Eulerian class. In this work, three Eulerian grid-based codes:ZEUS, ATHENA and NIRVANA (2D or 3D) are introduced to solve MHD problems. We discuss the category of grid generation (Structured mesh, Unstructured mesh and Cartesian mesh) as well. Indeed, the main challenge for computational MHD in astrophysics is the huge discrepancy in space scaling and complex physical process coupling (shock-turbulence).
