flac3d  手册上动力分析的原例子，怎么运行时提示“unrecognized parameter 4（not）”？？？盼高手指点迷津！！！不胜感激！急急急！！！

大拿都哪去了，咋没人响应呢？

kengawk

应该是某个命令格式有误

zhdy2008

或者某个输入有误

xinmj10

我有时也出现这种情况，但输入第二遍的时候有时候就好了，有时候还是不行

这不是告诉你了吗？不认识一个叫“not”的东西出问题了。
就在你命令里找吧，就一个not。在这里 fix y z range=(not bottom)
你把它改成 fix  y z range group bottom not
再试……
