<p>PURPOSE:To reduce the calculation processing quantity of the whole particles by setting the attribute of a stationary state or a fluctuating state to plural particles in space and applying respectively different attribute information calculation method. CONSTITUTION:After a primary attribute information setting part 1 sets the primary attribute of the particle to an attribute information storage part 2, a state/change information deciding part 3 decides attribute information of the particle and attribute information of the particle is calculated through the use of respective calculation parts namely a stationary state calculation part 5 in a stationary state, a neighborhood particle serching part 4 and a fluctuating state calculation part 6 in a fluctuating state and a neighborhood particle serching part 4 and a changing state calculation part 6 in a changing state.</p> |
