abaqus冲压模拟出现的一个错误Excessive incremental rotation如何处理?

我在做板料冲压的模拟,有一些inp文件job提交了,计算了8~9个小时后,运行Aborted,检查状态文件.sta
在许许多多的增量步的最后,出现了如下的几个errors,请高手分析一下,这是什么原因?
***ERROR: Excessive incremental rotation of element number 115 of instanceBLANK_1.

***WARNING: In element 115 of instance BLANK_1 the ratio of deformation speedto wave speed is 0.34462 at increment 104552. See the message filefor further information.

***ERROR: There is only one element with excessive rotations

The following checklist may be helpful in diagnosing the error:

    1. Check contact definitions for problems such as excessive initial
       overclosure or unrealistic tied definition between contact pairs.
       A vector plot of velocities or accelerations will usually help to
       identify contact problems.

    2. Check stiffness (elastic modulus) and mass (density) definitions for
       consistent units and verify that the combination is reasonable.

    3. Check for poor mesh definition.

    4. Check the boundary conditions for an excessive loading rate. The
       *DIAGNOSTICS, DEFORMATION SPEED CHECK=DETAIL option may be used to obtain
       detailed diagnostics information.

    5. Check the current status of the structure to see if it has
       totally failed.

    6. A dashpot or a very stiff spring may cause the analysis to go unstable.
       The *DYNAMIC, DIRECT option may be used to control the time incrementdirectly.

***ERROR: The fatal error will generate a new field output in the last
          increment. All variables applicable to the current procedure and
          material type(S) will be written to the output database.

THE ANALYSIS HAS NOT BEEN COMPLETED

这个我也遇见过,我的问题是通过重新设定接触来解决的。

应该是集合建模的问题

顶一下,期待解决

哈哈2004年的问题   今年2014年   时隔那么久这么问题 还是没有解决哎   看的我心都碎了

重新设定接触的感谢你,我的是接触属性用的是罚-摩擦系数,相互作用用的是运动接触,改成罚接触好了
