摘要
在CAE仿真分析中 ,网络划分是一个很重要的环节 ,它决定着分析结果的精度和计算成本。本文通过对两个实例的有限元计算结果的分析 ,对CAE仿真分析中计算精度与网格划分关系进行了讨论。在保证所建有限元模型正确的前提上 ,结合作者的使用经验 ,对计算精度和网格划分的关系提出了建议。
Meshing is playing an important role in the CAE simulative analysis.It can affect only the calculating precision and also cost of analysis.The Relation of calculating precision and meshing was discussed in the CAE simulative analysis,which was based on the finite element analysis result of two examples,in this paper.While the FE model is built exactly,and experience was considered,the suggestions were presented about the relation of calculating precision and meshing.
