摘要:
光滑粒子流体动力学（SPH）法是一种无网格拉格朗日粒子法。文中介绍了SPH法的常数和线性连续性条件,测试求解一维溃坝问题时不同的初始粒子配置对实验结果的影响。结果表明在SPH法中,初始时刻粒子应尽量均匀分布,并且尽量使所有粒子的质量相同或者是呈连续变化的
Abstract:
Smoothed particle hydrodynarnies（SPH）method, as a meshfree, Lagrangian, particle method, is developed in the past twenty years. In this paper, firstly, the zeroth - order consistency and linear consistency are introduced and then the influence of initializing particle configuration on the result in solving one - dimensional dam- break problem is examined. The results show that in the initialization all particles should be configured as uniform as possible, and their mass should be made equally or to change continuously
