【讨论】请教一个简单的问题！！！

victorkong

自己是个新手，现在在做一个力学结构分析。
准备用SHELL单元来建模，遇到一个问题，但是自己查了一下，没有查到
建模时，截面尺寸应该是用外截面尺寸还是中性面的？
（在ANSYS中是用中性面的尺寸的）
希望高人给指点一下，最好能给指点一下在随机帮助中去查哪儿！
谢谢了！

When modeling with shell elements, the reference surface is typically coincident with the shell's midsurface. However, many situations arise in which it is more convenient to define the reference surface as offset from the shell's midsurface. For example, surfaces created in CAD packages usually represent either the top or bottom surface of the shell body. In this case it may be easier to define the reference surface to be coincident with the CAD surface and, therefore, offset from the shell's midsurface. __ Getting started with Abaqus/Standard 5.1.4

谢谢WON2K的热心帮助。
看来随机帮助中的东西还是很深的，以后还是得继续阅读呀！
不过，总感觉ABAQUS中的CAE建模能力不是很强呀！
