提出一种基于光滑粒子流体动力学(SPH)方法的流体与可变形固体双向交互模拟方法,将流体和可变形固体统一由连续介质运动控制方程进行刻画,使流体模型和固体模型具有统一形式,避免了为流体和固体建立复杂的耦合接口.流体和固体均由粒子构成,每个粒子具有各自的物理属性,如粒子类型、质量和速度等.由于每个粒子可以与相邻的任何类型粒子发生交互,因此可以直接实现双向的流体和固体交互模拟.实验结果表明本方法能够快速、真实地模拟流体-可变形固体的交互现象.%A SPH-based simulation method for the two-way interactions of fluids and deformable solids is presented. Both fluids and solids are described by smoothing particle hydrodynamics, thus the fluids model and the solids model have the same form, which avoids complex interface for coupling fluids and solids. Fluids and solids are composed of particles with physical properties, such as type, mass and velocity, etc. Since each particle will interact with all neighboring one, the two-way interaction simulation can be implemented directly. The experimental results show that this method is capable of animating quickly the realistic interaction of fluids and deformable bodies.
