Abstract:
1. A method for calculating a force acting on an interface between immiscible fluids in an SPH (Smoothed Particle Hydrodynamics) based fluid simulation, the method comprising: calculating a force caused by viscosities of the fluids; calculating a force caused by pressures of the fluids; calculating an external force applied to the fluids from outside; and calculating an interactive force caused by interaction between the fluids, wherein the force acting on the interface between the immiscible fluids are obtained by a computer by using a sum of the force caused by the viscosities, the force caused by the pressures, the external force and the interactive force, wherein the interactive force is a surface tensional force calculated based on a pressure acting on the interface between the fluids at a contact surface of the fluids, and wherein the interactive force is calculated by using parameters representing scattering properties of the fluids, normal vectors of particles in the fluids, a magnitude of the force caused by the pressure acting on the interface between the fluids and an angle between a direction of the force caused by the pressure acting on the interface between the fluids and the interface of the fluids, wherein the interactive force is calculated by using the following formula:
