The atomistic simulation of track formation due to the moving of swift heavy ion is performed for uranium dioxide. The two-temperature atomistic model with an explicit account of electron pressure and electron thermal conductivity is used. This two-temperature model describes a ionic subsystem by means of molecular dynamics while the electron subsystem is considered in the continuum approach. The various mechanisms of track formation are examined. It is shown that the mechanism of surface track formation differs from the mechanism of track formation in the bulk. The threshold values of the stopping power for track formation are estimated.
