在这篇三篇论文系列中的第二篇中，我们继续详细描述 ZEUS-2D，这是一种用于模拟天体物理学中流体动力学流动的数字代码，包括对磁场和辐射传输影响的自洽处理。这里详细描述了 ZEUS-2D 中的磁流体动力学 (MHD) 算法。最近开发的约束传输 (CT) 算法用于 MHD 模拟磁场分量的数值演化。这种形式保证了数值演化场分量始终满足无散约束
In this, the second of a series of three papers, we continue a detailed description of ZEUS-2D, a numerical code for the simulation of fluid dynamical flows in astrophysics including a self-consistent treatment of the effects of magnetic fields and radiation transfer. Here, a detailed description of the magnetohydrodynamical (MHD) algorithms in ZEUS-2D is given. The recently developed constrained transport (CT) algorithm is implemented for the numerical evolution of the components of the magnetic field for MHD simulations. This formalism guarantees the numerically evolved field components will satisfy the divergence-free constraint at all times
