Hypermesh 新版本加入SPH单元划分功能

belonging

Smooth Particle Hydrodynamics (SPH) is a technique used to analyze bodies that do not have high cohesive forces among themselves and undergo large deformation, such as liquids and gases.  Use this panel to perform SPH  analysis on a component with volume, such as airbags or fuel tanks.  
In SPH Finite Point Method (SPH FPM), a given volume of the body of interest is discretized into particles, called SPH elements.  These elements are node-like particles which have no geometric connectivity among themselves.  Each SPH element has an effective mass.  The  summed mass of all particles in the filled volume of the body should be equal to the mass of the filled volume.


相比prepost的sph划分在单元质量计算方面更加方便，之需要输入part的密度或者mass，SPH单元质量会自动计算。并且支持在任意形状的面，体，网格，components基础上直接划分SPH网格。网格均匀，效果非常不错。（不一定非要原始有限元网格了）
不过同时ls-prepost的SPH划分功能也在开发中，相信不久就能看到新的SPH划分界面了。

楼主没有说怎么生成sph粒子。
