为什么用Discrete flexible link 做的钢丝在受压时会断啊
  我在钢丝下面放了弹簧
  但它说The corrector has not converged after 6 attempts. No. of iterations = 10.
WARNING: ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
   NOTE:  The set of redundant constraints has changed at time = 0.72159.
   ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
    The specified ending time for the simulation is less than or equal to
   the beginning time: Start time = 5.0 , End time = 5.0 .
ERROR:    The specified ending time for the simulation is less than or equal to
   the beginning time: Start time = 5.0 , End time = 5.0 .

我不明白

一般没见过断的

看这个提示看不明白什么问题，要不上传一个cmd文件。

如果怕泄漏，可以加分限制。或者再把问题详细说说。

不过看到这个错误：
ERROR: The specified ending time for the simulation is less than or equal to
   the beginning time: Start time = 5.0 , End time = 5.0 .

是不是先点一下这个按钮

是这样，我做的仿真要用到绳子。我不知道怎么做，只好用flexible link 做钢丝
代替。可钢丝好像没有想像中那么flexible

要使它more flexible，要增加段的数目

作者: peak 时间: 2003-6-30 22:11
每一段上都要加接触力的
我能加得过来
机器算不过来啊
有没有别的模拟绳子的方法啊

有别的方法吧
论坛里面不是有专门介绍怎么做cable的文章么
不过好像很难
