STRUCTURE MODEL GENERATOR, PARTICLE BEHAVIOR ANALYZER, STRUCTURE MODEL GENERATION METHOD, PARTICLE BEHAVIOR ANALYSIS METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To allow for placing spherical wall particles representing a structure to be in contact with particles without increasing calculation load when analyzing behavior of the particles using a discrete element method (DEM).;SOLUTION: A particle behavior analyzer is configured to extract points to be analyzed from point cloud data by means of three-dimensional measurement such that a spatial frequency distribution bears a blue noise characteristic, and sets up wall particles for the extracted points to be analyzed.;SELECTED DRAWING: Figure 10;COPYRIGHT: (C)2019,JPO&INPIT
