SIMULATION METHOD, SIMULATION APPARATUS, AND PROGRAM

In simulating a behavior of a particle system including a plurality of particles disposed in an analysis region, by using a molecular dynamics method, centroid velocities of the particles present in a local region including a particle of interest are converted on the basis of the number of particles present in the local region for each of the particles, and thus a conversion value of a centroid velocity of the local region is calculated. Temperature control of maintaining the temperature of the particle system to be a target temperature is performed by using a difference between a velocity of the particle and the conversion value of the centroid velocity of the local region including the particle as a velocity of the particle which is a basis for calculating the temperature of the particle system.
