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。
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.
