<p><P>PROBLEM TO BE SOLVED: To reduce communication load required for transferring calculation information between matrix elements when particle behavior analysis is conducted by employing a matrix-based division method. <P>SOLUTION: Based on distances between particles to be analyzed in the range of analysis, particles to be analyzed are distributed to particle behavior calculation units associated with one another by a matrix. For example, the particles to be analyzed are numbered so that the particles close to each other are included in the same matrix element. Alternatively, the arrangement of the particles to be analyzed in an area to be analyzed is sequentially associated with the numbers of particles of interest in a row direction of the matrix, to number the particles to be analyzed. In short-range force analysis, particles for one matrix (on both sides) are cut off. In long-range force analysis, n particles that satisfy 2n+1≤N-1 in a matrix of N lines are cut off. For particles not to be cut off, communication is not required for obtaining particle data. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
