Relativistic MHD with Adaptive Mesh Refinement
This paper presents a new computer code to solve the general relativistic magnetohydrodynamics (GRMHD) equations using distributed parallel adaptive mesh refinement (AMR). The fluid equations are solved using a finite difference Convex ENO method (CENO) in 3 + 1 dimensions, and the AMR is Berger-Oliger. Hyperbolic divergence cleaning is used to control the ∇ · B = 0 constraint. We present resul...
متن کاملA new MHD code with adaptive mesh refinement and parallelization for astrophysics
A new code, named MAP, is written in FORTRAN language for magnetohydrodynamics (MHD) calculation with the adaptive mesh refinement (AMR) and Message Passing Interface (MPI) parallelization. There are several optional numerical schemes for computing the MHD part, namely, modified Mac Cormack Scheme (MMC), Lax-Fridrichs scheme (LF) and weighted essentially non-oscillatory (WENO) scheme. All of th...
متن کاملAdaptive Mesh Refinement in Computational Astrophysics – Methods and Applications
The advent of robust, reliable and accurate higher order Godunov schemes for many of the systems of equations of interest in computational astrophysics has made it important to understand how to solve them in multi-scale fashion. This is so because the physics associated with astrophysical phenomena evolves in multi-scale fashion and we wish to arrive at a multi-scale simulational capability to...
متن کاملSelf-gravitational Magnetohydrodynamics with Adaptive Mesh Refinement for Protostellar Collapse
A new numerical code, called SFUMATO, for solving self-gravitational magnetohydrodynamics (MHD) problems using adaptive mesh refinement (AMR) is presented. A block-structured grid is adopted as the grid of the AMR hierarchy. The total variation diminishing (TVD) cell-centered scheme is adopted as the MHD solver, with hyperbolic cleaning of divergence error of the magnetic field also implemented...
متن کاملAdaptive Mesh Refinement and its Application to Magneto-Hydrodynamics
In this paper we present three improvements over the BergerColella’s adaptive mesh refinement (AMR) approach: adaptive clustering algorithm, conservative prolongation and restriction for cylindrical and spherical grid, and divergence-free reconstruction for AMR.
