无网格法中SPH方法和有限元方法的对比分析

The contrastand analysis of SPH method and FEM method

无网格法是近期发展起来的一种数值计算方法,根据形函数构造可分为多种样式在此主要介绍了较常用的一种方法:光滑粒子法(SPH)并对这种方法的原理和计算过程与有限元方法进行对比,从而阐述SPH方法的特点,后边又用这两种方法对一个简单例子进行求解。

Meshless method is new developing numerical method .It has many types by shape function .The useful method is introduced in this paper,The feature of SPH method is interpreted by contrast with FEM method ;at last an example is calculated.
