The image showed leaf-like peritoneal cavityfilling with air. Both ligamentum teres hepatic (arrow 1) and local abdominal adhesions (arrow 2) were seen clearly.
By the aided of numerical simulation technique we can not only accurate picture the cavityfilling process also can predict moulding fault among the die casting et al.
借助于数值模拟技术不仅能较准确的描述铸液的充型过程，而且能预测铸件内部的成型缺陷等。

The stages or steps in a casting process are the making of a suitable mold, the melting of the material, the filling or pouring of the material into the cavity, and the solidification.
