做了一个柔性锁具的动力学模拟，出现了如下的错误信息：
请高手指点：
ERROR:   
Static equilibrium analysis has not been successful.
  The maximum number of iterations 25, has been reached.
  For the last attempted iteration:
  The equation with the largest error was rope.partrope_202 Comp = 6 Error = 2411994.002403
  The variable receiving the largest increment was rope.JOINT_40 Comp = 5 Delta = 350712714.897453.
