Simulation on melting process of theoretically oriented ice formation was presented using molecular dynamics method under the atmospheric pressure. Two kinds of ice formations were prepared, namely, ferromagnetic and antiferromagnetic orientations. The analysis on melting process of the ice formations were carried out and the results were compared. Number of molecules consisted in ferromagnetic formation was 576 and in antiferromagnetic was 360. Periodic boundary condition was used in both cases to avoid surface effect. If the volume of the cell is fixed, variation of the pressure in the cell during melting process is big and it might influence the characteristics of the melting process, such as melting temperature. Therefore, constant pressure condition was applied in the analysis. Anisotropic variation was adopted for volume change of the cell. It was found that the difference in the melting temperature and the latent heat between the two ice formations were relatively big and the characteristics of ice in nature existed somewhere between them.
