It consists of unit topological changes occurrins at the microscopic level. Preliminary results are presented. Is is argued that further improvements will result from a revised expression of the total energy of the system that takes into account the tendency to equilibrate local forces at grain corners.text::conference output::conference proceedings::conference paper
