是不是大变形分析？ 变形过大吧
多谢楼主，dddddddddddddd

INCREMENT 1 STARTS. ATTEMPT NUMBER1, TIME INCREMENT1.000E-02
***WARNING: THE SYSTEM MATRIX HAS 58 NEGATIVE EIGENVALUES.
IN AN EIGENVALUE EXTRACTION STEP THE NUMBER OF NEGATIVE EIGENVALUES IS
EQUAL TO THE NUMBER OF EIGENVALUES BELOW THE CURRENT SHIFT POINT.
THIS MAY BE USED TO CHECK THAT EIGENVALUES HAVE NOT BEEN MISSED.
NOTE: THE LANCZOS EIGENSOLVER APPLIES AN INTERNAL SHIFT WHICH WILL
RESULT IN NEGATIVE EIGENVALUES.
IN A DIRECT-SOLUTION STEADY-STATE DYNAMIC ANALYSIS, NEGATIVE
EIGENVALUES ARE EXPECTED. A STATIC ANALYSIS CAN BE USED TO VERIFY THAT THE SYSTEM IS STABLE.
IN OTHER CASES, NEGATIVE EIGENVALUES MEAN THAT THE SYSTEM MATRIX IS NOT
POSITIVE DEFINITE:
FOR EXAMPLE, A BIFURCATION (BUCKLING) LOAD MAY HAVE BEEN EXCEEDED.
NEGATIVE EIGENVALUES MAY ALSO OCCUR IF QUADRATIC ELEMENTS ARE
USED TO DEFINE CONTACT SURFACES.

让我比较无语的是，你在265楼贴出来是信息：
1）很多是重复的，你直接copy上去是很省心，别人看起来不省心
2）你贴了那么多，是不是有些信息在1-4# 已经有了？
3）这个帖子里面这么多人回复，你看看有没有人是你这样回复的，连这些都发上来了

仔细看了下“THE INCREMENTAL ROTATION AT THE FIRST NODE OF THE CONNECTOR ELEMENT NUMBER 2805 IS VERY LARGE. THIS MAY LEAD TO INCORRECT INCREMENTAL ROTATION UPDATE”这个在1-4楼的确是没有，你上传你的模型，重新开个帖子问吧。初步看来，你这个可能是约束不足，有刚体位移。

看下顶置，看下此贴1-4楼，都有说的。
大家来这里发布新的错误信息，对后人解决问题能帮不少忙。
4 nodes have inactive dof on which boundary conditions are specified.模型中未施加任何边界条件，四个点都是在加载点处，使用RP将,RP和体绑定。看过两个帖子，但是依然未解决。

这个信息在1-4# 有总结。
如果是warning，忽略之。
如果是error，存在过约束。
272# zsq-w 这是一个ERROR,我很奇怪的是这四个 点都是荷载加载的地方，从字面上来理解是这样的，但是我没有在加载的局部我没有施加任何的边界条件，怎么还会有4 nodes have inactive dof on which boundary conditions are specified。这个模型以前做过瞬态响应分析，说是定义的MODEL DYNAMICS 分析步，那时并未发现这样的问题，现在换做IMPLICIT 却会出现这样的问题，但是事实上和分析步应该也没多大的关系啊

的确有点奇怪。 把cae和inp发上来看看。

问题已解决，我换了几个点就没有问题了，杯具，不知道原因还是！

出现这样的错误，感觉应该是格式错误，都是最后一行出错，是不是里面多了空格还是什么的，附上INP文件

很奇怪的信息。
inp是自己手写的，还是HM生成的，还是CAE生成的？
277# zsq-w
CAE生成之后自己进行了编辑，NOTEPAD，在ELEMENT关键字部分出错，总是提示这样的错误
还有总是在提示NODE0，实际上没有定义NODE0,应该是感觉后面有空格或者什么的，

编辑inp的时候，keywords manual里面没有规定需要空格和空行的地方，七万不要随意敲回车。
我将最后一个空行删除，就没有ls的信息了，基本正常：
