<p><P>PROBLEM TO BE SOLVED: To prevent reduction of calculation efficiency in particle behavior analysis applied a force division method. <P>SOLUTION: With respect to a particle allocated to a force matrix, coping is performed such that processing set with a cutoff distance is performed. When reduction to a minimum force matrix certainly including the particles inside a cutoff area is performed, the cutoff distance is adjusted such that a data amount for interaction calculation related to the particles inside the set cutoff area is stored within cache memory capacity. By paying attention to the particles inside the set cutoff area, the original force matrix is reduced to the force matrix such that the particles inside the cutoff area are certainly included by use of a substitute particle ID. Correspondence relation between an actual particle ID of an analysis target inside the cutoff area and the substitute particle ID in the reduced force matrix is managed. Interaction force of a calculation target shown by the reduced force matrix is obtained in reference to the correspondence relation between the actual particle of the analysis target inside the cutoff area and the particle in the reduced force matrix. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
