【Abstract】 The conserved scale method has been used to determine t he morphology of the free surface during mold filling. The disadvantages of much shorter time step in numerical simulation has been overcome by adopting two dif ferent time steps to calculate flow field and free surface, so as to enhance gre atly the calculation speed of the numerical simulation during mold filling and meet the accuracy requirement in the engineering application.更多还原
