论文摘要
历史上，数值模拟在理解潮汐破坏过程的流体动力学方面发挥了重要作用。考虑到系统的几何形状的复杂性，问题所带来的挑战确实刺激了数值方面的大量工作。例如，平滑的颗粒流体动力学方法已经在潮汐破坏的背景下看到了它们的第一个应用，并且至今仍起着重要作用。同样，最初用所谓的仿射方法模拟恒星的演变的初步尝试在历史上非常有用。在本章中，我们概述了该领域中使用的数值技术及其局限性，并总结了为潮汐破坏过程模拟所做的工作。
Numerical simulations have historically played a major role in understanding the hydrodynamics of the tidal disruption process. Given the complexity of the geometry of the system, the challenges posed by the problem have indeed stimulated much work on the numerical side. Smoothed Particles Hydrodynamics methods, for example, have seen their very first applications in the context of tidal disruption and still play a major role to this day. Likewise, initial attempts at simulating the evolution of the disrupted star with the so-called affine method have been historically very useful. In this Chapter, we provide an overview of the numerical techniques used in the field and of their limitations, and summarize the work that has been done to simulate numerically the tidal disruption process.
