中文摘要：

针对模拟流体，提出了一种基于定位流体方法的改进模型，继承了定位动态学方法的稳定性以及光滑粒子流体动力学方法的光滑性，通过将流体粒子按速度值动态分配支集半径和给流体粒子添加密度限制来增加计算准确性并加强流体的表面细节的模拟效果．

英文摘要：

This paper puts forward an improved model for fluid simulation according to Position Based Fluids, which inherits the stability of Position Based Dynamics （PBD） method and the smoothness of Smoothed Particles Hydrodynamics （SPH） method. In this method, according to velocity and added density constraints effects. we distrabuted different supported radius for different particles for paticles, which improved calculation accuracy and simulation
