APPARATUS, METHOD, AND COMPUTER PROGRAM FOR PERFORMING SPH-BASED FLUID ANALYSIS SIMULATION

摘要

A smoothed-particle hydrodynamics (SPH)-based fluid analysis simulation apparatus comprises: an input unit for receiving, as an input, data about a plurality of particles, for a fluid analysis simulation; a space formation unit that divides, into a plurality of cells, the space in which the plurality of particles are present, and generates cell indexes on the basis of the locations of the cells in the space where the plurality of particles are present; a particle search unit for searching for at least one neighboring particle that neighbors a target particle, on the basis of particle reference information about the plurality of particles and cell reference information about the plurality of cells; and a flow data calculation unit that calculates flow data between the target particle and the at least one neighboring particle, and performs a fluid simulation on the basis of the flow data for the plurality of particles.
