【请教】使用rigid link施加角速度时的问题
我想对结构施加旋转运动。按照版里提供的方法，先对体上某一点施加旋转运动，如下图所示
然后使用rigid link命令，
运行产生如下提示，请问这是什么情况？（PS：我把自由度限制为仅绕Z轴转动）

No displacement loads generated at point 37
resulting from load application 1. 重新在某个face上建了一个点，上面的问题已经解决。
个人认为，该point必须存在于face/surface上，才能使用rigid link。请高手指教。
一个问题解决了，又出现新的问题……菜鸟伤不起啊。
继续研究！！！ 主点可以是离散的点，但是划分网格时不要忘了给主点划分网格。 回复 3# wild_field
哦？是因为没有给主点划分网格？怎么给点划分网格啊？ 回复 3# wild_field
请教一下斑竹，“Prescribed displacement unloading option cannot be used in linear analysis”这个错误怎么处理（设置与上面一样）。谢谢啦~ 要对施加运动的主点划分点网格单元问题就能解决了！ zouchangfang 发表于 2011-9-8 15:58 static/image/common/back.gif

我试试，谢谢！
