The simulation results are compared with the simulation results using SOLA VOF algorithm. The results show that the filling process and the temperature distribution of the casting are reasonable, and the design goal of providing accurate initial temperature field for subsequent solidification simulation is achieved. The simplified arithmetic operation time is short, which can meet the computing time requirements in practical applications
