摘　　要：提出了一种适用于有限差分法凝固过程数值模拟的实用三维几何造型方法．这种方法是先把一定范围的空问进行网格划分，然后对每一点进行位置及属性的记录，把同一物质属性的点排列出来，即可得到三维几何实体图形。它的数据结构本身就是几何实体的形状，因此占用内存少，操作方便，运算速度快。A Prectical geometyic modelling method for solidification sublation whichis suitable for finite difference method has been deVeloped in this paper.Themodelling method is as follows,lattice division in a given scope of the space,record of position and attribute for eaCh point and arrangement of everypoint which is the matter of same attribute,then the 3-D graph was obtained.The data structure is in itself geometric shape of matter,therefore it has afew intercal storage,easy to operation and fast operation speed.
