Abstract
In the field of continuum mechanics, there is a need to hypothesize empirical rule such as the constitutive laws. If the discipline governing the dynamics at an atomic/molecular level is considered, it is believed that the physical properties, such as the stress intensity factor unique to the material, may be predicted. For obtaining such information from the computations, it is required to solve a system of massively clustered particles. To do this end, the authors have developed a parallel algorithm for computing the motion of particles, which is described by the pair potential. The developed program carries out the domain decomposition, which divides the domain into arbitrary number of sub-domains. PVM, or the parallel virtual machine, is implemented as the message passing library in the parallel environments. By using this program, apply to 2.56×107 particles problem.
