摘要

铸件及铸型实体的三维网格自动剖分是金属凝固模拟按实际形状顺利进行的前提条件。应用将剖切面偏移奇异点的“切片法”对STL文件进行网格自动剖分

所生成的三维直角六面体网格为金属凝固数值模拟采用有限差分法计算提供了铸件和铸型实体的空间位置信息。该方法原理简单、编程实现快捷、适用于剖分任意形状的实体

是一种高效、高精度的剖分方法

Abstract

The 3D mesh automatic generation of casting and cast mold is a prerequisite for metal solidification simulation of real shape. Using slice method and making the slice a little offset from oddity point

generated 3D right angle hexahedron mesh by automatic mesh generation based on STL files provided space location information on casting and cast mold for finite differential calculation in solidification simulation. The method with simple theory and rapid programization is a high efficient and accurate technique suitable for meshing entity with arbitrary shape.
