High Effective Simulation Of Liquid-Solid Coupling For Complex Scene

In Computer Graphics,the simulation of natural scenes has always been a hot topic.And,simulation of liquid-solid coupling for complex scenes is widely used in the fields of disaster simulation,Virtual Reality,Video special effect and other related fields.However,those conventional methods of fluid simulation which simplify the problem of the interaction between fluid and solid cannot simulate complex fluid-solid coupling scenarios such as collapse,dam break and so on.They are restricted to relative small-scale scenes as well as simulating fracture animation with objects.To overcome the defaults mentioned above,we propose a method to handle high effective simulation of liquid-solid coupling for complex scenes.In the first chapter,we improve the traditional divergence free smoothed particle hydrodynamics method with the Fluid Implicit Particle and come up with a new fluid simulation method which can simulate millions fluid particles efficiently.On the one hand we enforce the incompressibility of fluid with DFSPH,on the other hand we utilize implicit particles to enrich the details.The new method enable more particles participate which makes the simulation of large-scale scenes possible.In the second chapter,we handle the motion problem of fluid and solid based on which two,solid or fluid,are the participants.According to the different scenarios,we adopt different strategies mentioned in this chapter.In the third chapter,a controllable rigid body fracture method is proposed so that the solid can be broken under the action of:fluid.The results show that the proposed method can be successfully applied to the solid-liquid coupling simulation in complex scenes.Compare with conventional DFSPH method,under the scene with one million fluid simulation,our method is much faster with similar simulation results.
