| Abstract: | Computing speed of numerical simulation on filling process of casting is a focus and difficulty in the study of this field. The mathematical model of numerical simulation on filling process is summarized and a scheme of algorithmic optimization is put forward in the article. The scheme can improve the computing speed of numerical simulation on filling process of casting by decreasing search time of the cells in the casting and mould. The merit of this method is that it can speed the calculation of numerical simulation on filling process of casting without effecting the precision of calculation. |
