移动质点半隐式(MPS)方法是利用质点概念分析连续介质力学的质点方法之一。由于不使用网格，因此可以模拟自由曲面和材料界面的大变形，而不存在网格变形的问题。因此，MPS方法已应用于核工程中的多相流分析。粒子方法的优点还可用于其他工程领域：船舶工程、土木工程、微流、生物力学、可视化等。本文对计算实例进行了描述和分类。商业代码已经发布，并在行业中应用。粒子方法也被用于电视节目、电影和电脑游戏中。多物理问题的数值技术、快速计算和高质量可视化的结合有望在不久的将来为各种新的应用带来实时粒子模拟。
The Moving Particle Semi-implicit (MPS) method is one of the particle methods in which continuum mechanics is analyzed using the concept of particles. Since meshes are not used, large deformation of free surfaces and material interfaces can be simulated without the problems of mesh distortion. Thus, the MPS method has been applied to multiphase flow analysis in nuclear engineering. The advantages of the particle methods are also useful for applications in other engineering fields: ship engineering, civil engineering, microflow, biomechanics, visualization, etc. In this review, calculation examples are described and classified. Commercial codes have been released and applied in industries. The particle methods are also used in TV programs, movies, and computer games. Combinations of numerical techniques for multiphysics problems, fast calculations, and high-quality visualizations are expected to lead to real-time particle simulations for various new applications in the near future.
