Details of the Potts-MC-type simulation model modified to reduce computing time were explained and effects of parameters to control anti-freezing of the structure, orientation-relation-dependent migration rate and energy of boundaries as well as orientation-relation-dependent migration rate of triple lines on the elementary structural development process were presented. Some topological characters of the structures observed by the modified method were then compared with earlier reported ones. Most of them coincided with the earlier reported results. The critical grain size has been found to coincide with the topological mean grain size. The transition probabilities of grains between topological classes in the shortest elapsed time are reported for the first time; they suggest that the steady state topological grain size distribution could exist for only a short period.
