There is two methods used most in the casting process simulation to determine the flowing front at present: the VOF method and the conservation scalar quantity method.
前言： 在铸造模拟中，目前流动前沿的难题处理上，用得较多的有两种方法：V OF法和守恒标量法。
In order to get rid of some existing shortcomings of the conservation scalar quantity method, it was simplified under the precondition that the law of the physical conservation was being observed.
笔者针对守恒标量法的某些缺点，在遵守物理守恒定律的前提下，对其进行简化。
