–划分网格的目的是把求解域分解成可得到精确解的适当数量的单元.–3D 网格的基本形状有:四面体六面体棱柱(非结构化网格)(通常为结构化网格)(四面体网格被拉伸时形成)棱锥(四面体和六面体之间的过渡)集流管例子: 热应力气流分析的外部铸件和内部流体的网格划分Training Manual网格详述需考虑的事项•细节:–多少几何细节是和物理分析有关的–不必要的细节会大大增加分析需求有必要划分这里•细化–哪些是复杂应力梯度区域？这些区的网格吗？域需要高密度的网格.流体边界层的网格在螺栓孔附近进行网格细化网格详述Training Manual •效率–(内存/ 运行时间)。

要在分析精度和资源使用方面大量的单元需要更多的计算资源/要在分析精度和资源使用方面进行平衡。

网格详述Training Manual •质量–复杂几何区域的网格单元会变扭曲。

劣质的单元会导致劣质的结果，或者在某些情况无结果!()–有很多方法来检查单元网格质量(mesh metrics*)。

例如，一个重要的度量是单元畸变度（Skewness ）。

畸变度是单元相对其理想形状的相对扭曲的度量，是一个值在0 (极好的) 到1 (无法接受的)之间的比例因子.00250250500500800800950950980981000-0.25 0.25-0.50 0.50-0.80 0.80-0.95 0.95-0.98 0.98-1.00Excellent very good good acceptable bad Unacceptable *更多检查网格的信息在培训讲稿的附录文件中。

网格详述Training Manual优质和劣质网格区别的例子:这个例子列举了一个集流管固体铸件中不收敛的热场。

很明显劣质单元区域的分析不可能得到切合实际的数据场。

优质单元例子的求解场证明没有问题。

ANSYS 网格应用程序提供了提高网格质量的工具。

About 700 monkeys live in the forests near Hong Kong and they usually come to the city to eattheir meals.The monkeys take bags of groceries from old women，take bread from babies，go into flats through open windows and take fruit from kitchen tables. In some flatsthe monkeys find cans of beer. They open the pop-top cans and drink the beer.The people of Hong Kong don’t want the monkeys in their city. They say，‘ Hong Kong is not a good place for moneys. The forest is a good place for monkeys.’But the monkeys don ’t want to eat in the forest because there is no bread inthe forest，and there is no beer either.So， every day the monkeys come into the city.
