<p><P>PROBLEM TO BE SOLVED: To provide a simulation method which attains precise simulation, and to provide a program therefor. <P>SOLUTION: The simulation method is the method in a particle method for analyzing the state of an object by each discretely distributed time on a temporal axis by expressing the object as the aggregation of particles and calculating the action of each particle as a numerical value by certain time width. The method includes: (a) a process for calculating frictional force to be applied on first particles and second particles, based on relative speed at the first time point between the first particles constituting the first body and the second particles constituting the second body (S105); and (b) a process for obtaining the positions of the first and second particles at the second point time point next to the first time point by considering the frictional force calculated in the process (a). <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
