综合介绍了一种新的纯(Lagrangian 方法——光滑质点流体动力学(SPH) 方法,
由于它计算空间导数时不需要使用网格, 从而避免了高维拉氏差分网格法中的网格缠结和扭曲的 …

Numerical simulations are presented for viscous incompressible flows with and without solid
wall boundaries. Our numerical method is based on vortex methods. The classical inviscid …

This paper describes a new and pure Lagrangian method——called" Smoothed Particle Hy
drodynamics"(SPH) method. The method is to actually evaluate spatial gradients without the …

We present and test a general-purpose code, called PPASPH, for evolving self-gravitating
fluids in astrophysics, both with and without a collisionless component. In PPASPH …

抄録 To simulate the crater formation into the granular material covering the majority of the
surface of a planet, a satellite, a comet nucleus or an asteroid by high-speed impact of a …

Ubiquitous and captivating, fluid—gaseous and liquid—motion is often desired in computer
animation. For example, rives, lakes, and clouds enhance flights simulations. Realizing …

Simulations of shock-wave reflection in a model one-dimensional shock tube have been
made using a Lagrangian technique called smoothed particle hydrodynamics. Different …
