Abstract
To obtain velocity, density, pressure, and a position per unit time, acceleration of each particle and a repulsive force applied to each particle from a boundary surface is obtained by an equation of motion discretized by a predetermined kernel function; velocity after unit time is calculated by time integration; a density time differential is calculated by a discretized continuity equation representing a temporal change in the density based on a predetermined kernel function; density after unit time is calculated by time integration on the density time differential by using the velocity after the unit time; smoothing is performed on the density at predetermined intervals; pressure after unit time is calculated by an equation of state with the density after unit time; a position after unit time is calculated; the above calculations are repeated from the initial state to the end of a predetermined time.
