<p><P>PROBLEM TO BE SOLVED: To provide a simulation device capable of following three-dimensional behavior of a particle. <P>SOLUTION: A simulation device comprises: a velocity calculation section which calculates a velocity of a particle at each position based on simulation result information on a time series variation of a physical quantity of the particle obtained from a simulation of a fluid flow; a grouping section which calculates a distance between the two particles based on the positions of the particles, calculates a difference in the velocity between the two particles based on the velocities of the particles, groups the two particles if a value of the distance between the particles is smaller than a first threshold and a value of the difference in the velocity between the particles is smaller than a second threshold; and a drawing information generation section which generates drawing information to draw display objects visualizing the grouped two particles based on velocity vectors of the grouped two particles. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
