ZEUS-2D : a radiation magnetohydrodynamics code for astrophysical flows in two space dimensions. II : The magnetohydrodynamic algorithms and tests

摘要: In this, the second of a series three papers, we continue detailed description ZEUS-2D, numerical code for simulation fluid dynamical flows in astrophysics including self-consistent treatment effects magnetic fields and radiation transfer. Here, magnetohydrodynamical (MHD) algorithms ZEUS-2D is given. The recently developed constrained transport (CT) algorithm implemented evolution components field MHD simulations. This formalism guarantees numerically evolved will satisfy divergence-free constraint at all times
