Title:
SIMULATION METHOD AND PROGRAM
Document Type and Number:
Japanese Patent JP2010170309
Kind Code:
A
Abstract:

To provide a new simulation method which attains high-accuracy simulation.

The simulation method in a particle method includes analyzing the state of an object at each time discretely distributed on a time axis by expressing an object as group of particles, and numerically calculating the behavior of each particle based on a certain time width. The simulation method includes: (a) calculating the positions of a plurality of particles at a second time next to a first time based on a force acting on each of a plurality of particles at the first time; (b) configuring a Voronoi polyhedron based on the positions of the plurality of particles at the second time; and (c) calculating the temperature of the object at the positions of the plurality of particles at the second time based on the temperature of the object at the positions of the plurality of particles at the first time and the dimension and relative position relationship of the Voronoi polyhedron configured in the process (b).
