PURPOSE:To reduce the calculation quantity of mutual operation on respective particles by registering particles which are close to each particle at intervals of a large time step number and discriminating nearby particles within an optional radius among the registered particles at intervals of an optional time step number. CONSTITUTION:Particles which are closed to each particle within a radius larger than the optional radius are registered previously at intervals of the large time step number larger than the optional time step number and the particles which are close within the optional radius are discriminated among the registered particles at intervals of the optional time step number. For example, particles which are close to each particle within a radius of 6.5Angstrom are registered previously in every 100 steps and particles which are close to each particle within a radius of 4.5Angstrom are discriminated among the registered particles in every 10 steps. Consequently, the number of the discriminated nearby particles decreases and the frequency of calculation required for the nearby particle discrimination is reduced to greatly shorten the time for discriminating the nearby particles. |
