Patran/Nastran。在接触表格(Contact Table)界面有一个选项是"Distance Tolerance"，这个表示的是什么意思？麻烦知道的人解释一下，非常感谢！

Answer 1

你要学会查软件的帮助手册Tolerance is the distance at which the solver starts to consider the possibility of contact. If two parts are a significant distance apart, it is not necessary to consider contact until the two objects are close to being in contact. By defining this value, it will reduce computation time in looking to activate contact.
就是说设定两个部件距离小于何者时候，系统认为他们接触

那应该怎么查看软件的帮助手册呢？

要安装MD Nastran Quick Reference Guide呀，然后就和查其他文档一样去搜索关键词
