A method for calculating a force acting on an interface between immiscible fluids in an SPH (Smoothed Particle Hydrodynamics) based fluid simulation includes: 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. The force acting on the interface between the immiscible fluids are obtained by using sum of the force caused by the viscosities, the force caused by the pressures, the external force and the interactive force. The interactive force is a surface tensional force calculated based on a pressure acting on the interface between the fluids.
