摘要
In an information update step of a particle and a lattice including the particle in an information preservation method based on a direct simulation Monte-Carlo method, the present invention relates to a particle and lattice information correcting method including: a particle selecting step of selecting a particle with a temperature lower than a reference temperature among the particles in the lattice; a relaxation function factor calculating step of calculating a relaxation function factor using a ratio of the particles selected to the particles in the lattice; a temperature variation calculating step of calculating a temperature variation using the relaxation function factor; and a bank temperature updating step of updating a bank temperature using the temperature variation. The temperature variation is calculated by applying an unselected particle weight and a selected particle weight using the relaxation function factor with regard to the selected particles and the unselected particles in the temperature variation calculating step. Accordingly, the present invention can stably and easily update and correct the temperature of the particle.
