摘要

介绍了有限差分网格剖分中存在的误差

误差和剖分精度有关

由误差带来的型腔不连通

会使模拟失败或得到错误的结果 ;对由该误差引起的型腔连通性进行了探讨。通过对连通区域进行递归算法提出了对剖分后型腔连通性进行检测的方法

Abstract

The errors encountered in FDM mesh generation were introduced.The errors were related to mesh precision.Problems of mould cavity connectivity caused by the errors were discussed. And then a method to detect mould connectivity after FDM mesh generation was presented.
