The time evolution of average W6 of internal atoms, suface atoms and surface atoms with nearest-neighbor bonds are shown below. Those of internal atoms and surface atoms with nearest-neighbor bonds are from the simulations (Andersen Thermostat during step-by-step cooling). That of surface atoms are calculated from saved 100 configurations without bonds to internal atoms. These plots didn't show any evidence that surface solidification is prior to interior.

Surface and interior cooling time

603 atoms at 800K

1409 atoms at 800K
