光滑粒子流体动力学：我希望我妈妈教我的事情
Smoothed Particle Hydrodynamics: Things I wish my mother taught me
摘要：
我讨论了光滑粒子流体动力学（SPH）作为一种数值方法的主要特点-特别是SPH和更标准的基于网格的方法之间的关键差异-这对从业者很重要。这些包括对流的精确处理，没有内在耗散，精确的守恒和更微妙的性质，产生于其哈密顿公式，如粒子的最低能量状态的存在。每一个这些的影响进行了讨论，显示它们如何可以是优点和缺点。
英文摘要：
I discuss the key features of Smoothed Particle Hydrodynamics (SPH) as a numerical method - in particular the key differences between SPH and more standard grid based approaches - that are important to the practitioner. These include the exact treatment of advection, the absence of intrinsic dissipation, exact conservation and more subtle properties that arise from its Hamiltonian formulation such as the existence of a minimum energy state for the particles. The implications of each of these are discussed, showing how they can be both advantages and disadvantages.
