We use molecular dynamics simulations to determine the melting point of ice Ih for the polarizable POL3 water force field (Caldwell and Kollman, J. Phys. Chem. 1995, 99, 6208). Simulations are performed on a slab of ice Ih with two free surfaces at several different temperatures. The analysis of the time evolution of the total energy in the course of the simulations at the set of temperatures yield the melting point of the POL3 model to be Tm = 180 ± 10 K. Moreover, the results of the simulations show that the degree of hydrogen-bond disorder occurring in the bulk of POL3 ice is larger (at the corresponding degree of undercooling) than in ice modeled by non-polarizable water models.
