abaqus错误提示信息(ABAQUS error message)
Q: an error occurred while I was running abaqus:
ABAQUS error:the executable
C:\abaqus\6.5-1\
Aborted with system error "deny access" (error code 5)
Answer:
First look at the DAT and MSG files, there is no warning or error, if not, there are three common reasons:
The parameter pre_memory in v is too large
- a problem in the user subroutine. Check whether the correct parameters are used when calling the user subroutine in the INP file. You can try to debug a user subroutine with a simple example to ensure its correctness. In addition, when writing user subroutines, we should pay attention to set up some error prompts as much as possible.
-
ABAQUS's own bug. You can try to get rid of unnecessary special settings in the model, and try to use the default values of ABAQUS as much as possible. If the initial model has no problem, and after modifying some parameters, the above error information can be tried to restore these parameters one by one to the initial state.

Is the software not working out?
If you take a few steps, look at the.Dat and.Msg files, search for error, and see what the specific problem istruncated模型用什么软件
The grammar seems right
In general, the tie binding constraint: the action is to bind the two parts of the model together, and there is no relative movement between the two, which is equivalent to welding together. If A and B are A binding, and B with node degree of freedom always exactly the same, this is the same effect with the coupling of ANSYS, ABAQUS in the surface and face binding is the degree of freedom coupling surface corresponding to the node. The definition of Tie master and slave surfaces is similar to that of
contact. When the stiffness, size and roughness are contradictory, the size and roughness are dominant
However, contact requires add and remove operations, and tie does not require such operations. It only needs to be defined before the analysis step is started, and no action is performed in the analysis step.
If the zero pivot appears in the MSG file, it shows that the InP has defined the over constraint condition, and ABAQUS cannot solve the over constrained problem automatically. For example, in some part, the tie is defined, and the contact is defined. The solution is to set the type to node region when choosing the slave surface of tie or contact, and then do not include the adjacent public nodes when choosing the region.
In addition, it should be helpful to make the distance slightly smaller.
Finally, try more and think more. What are the problems after the problem solving, how to solve the problem, huh?

Detected lock file Job-1.lck. Please confirm that no other resubmitting. applications are attempting to write to the output database associated with this job before removing the lock file and
Just delete the.Lck file (that is, locking lock of the calculated file),
The file is generated in the calculation process,
To prevent its program or artificially modifying the file related to the job file,
After the normal calculation, the.Lck file will be deleted automatically,
The file is retained when the force is broken,
If you run with the InP of the same name, it will appear:
Error in job Job-1: Detected lock file Job-1.lck. Please confirm that no other applications are attempting to write to the output database associated with this job before removing
the lock file and resubmitting
Delete the.Lck file

模型不能算或不收敛,都需要去监控、味精文件查看原因,如何分析这些信息呢?这个需要具体问题具体分析,但是也存在一些共性。这里只是尝试做一个一般性的大概的总结。如果你看见此贴就认为你的警告以为迎刃而解了,那恐怕令你失望了。不收敛的问题千奇万状,往往需要头疼医脚。接触、单元类型、边界条件、网格质量以及它们的组合能产生许多千奇百怪的警告信息。企图凭一个警告信息就知道问题所在,那就只有神仙有这个本事了。一个警告出现十次能有一回参考这个汇总而得到解决了,我们就颇为欣慰了。
类似于:
固定时间太大
Too many attamps have been made
解决方案似乎是发散的。
收敛下不可能。
Time increment required is less than the minimum specified
这样的信息几乎是无用信息(除了告诉你的模型分析失败以外,没有告诉你任何有用的东西)。宜再查别的信息来考察。根据经验,改小增量步也不一定能收敛,虽然也有人报告过改好的先例,我是从来
没有遇到过,也从来没有那个奢望。所以我一般从模型的设置入手。
必须说明的是:错误和警告的性质是完全不同的。错误意味着运算失败,但出现警告可能还能算,而且有些运算必定会出现警告(比如接触分析必定出”负特征值”,下有详述)。很多警告只是通知性质的,或者只是说明一下而已,不一定都是模型有问题完全可以忽略比如以下警告:
xxxxx将(不)印刷,这种只是通知你一声,某些玩意儿不输出了。还有:
参数频率不能与参数字段一起使用。它将被忽略(都说某某被忽视了)。A系列
如果模型能算,且结果合理,那么大部分警告信息可以不管。但是以下除外:
1数值奇异性(数值奇异):刚体位移(欠约束)
求解问题。当node105数值奇异处理实例
pile D.O.F. 1 ratio=1.735e13
2零轴(零主元):过约束或者欠约束。
这2个问题一般都意味着模型约束存在问题。1)、都会伴随着产生大量负特征值解决方案当然第一步是检查约束了2)。
