Tidal disruption events involve numerous physical processes (fluid dynamics, magnetohydrodynamics, radiation transport, self-gravity, general relativistic dynamics) in highly nonlinear ways, and, because TDEs are transients by definition, frequently in non-equilibrium states. For these reasons, numerical solution of the relevant equations can be an essential tool for studying these events. In this chapter, we present a summary of the key problems of the field for which simulations offer the greatest promise and identify the capabilities required to make progress on them. We then discuss what has been—and what cannot be—done with existing numerical methods. We close with an overview of what methods now under development may do to expand our ability to understand these events.

潮汐干扰事件的未来模拟

潮汐破坏事件以高度非线性的方式涉及许多物理过程（流体动力学、磁流体动力学、辐射传输、自重力、一般相对论动力学），并且由于 TDE 根据定义是瞬态，经常处于非平衡状态。由于这些原因，相关方程的数值解可以成为研究这些事件的重要工具。在本章中，我们总结了模拟最有希望的领域的关键问题，并确定了在这些问题上取得进展所需的能力。然后，我们讨论使用现有数值方法可以完成和不能完成的工作。我们最后概述了现在正在开发的方法可以做什么来扩展我们理解这些事件的能力。
