查看 ErrElemExcessDistortion 的 Elements

Abaqus 可能会提示有些 Elements 出现了过度变形,并提示可以通过 element set ErrElemExcessDistortion 查看。即使该模拟中途因错结束,也可以在输出中查看到这些单元。

错误提示类似于,

The elements contained in element set ErrElemExcessDistortion-Step1 have distorted excessively.
There are a total of 4 excessively distorted elements

查看的方法就是,

  1. 右键单击该 Aborted 的 job 并单击 Results,或者在 Job Manager 中点击 Results 打开输出结果查看页面。
  2. 在 Results 列表中展开该 job 对应的 odb。
  3. 继续展开 Element Sets,或者 Node Sets,或者 Surface Sets。
  4. 单击要查看的 Set 的名字,如 ErrElemExcessDistortion。- 号后面是 Step 名称。

其它类似提示也可以通过这样的方式查看到。比如,

90 elements are distorted. Either the isoparametric angles are out of the suggested limits or the triangular or tetrahedral quality measure is bad. The elements have been identified in element set WarnElemDistorted.

就可以通过上面的方式打开 Set 集,单击 WarnElemDistorted 来查看。

还有,

Excessive incremental rotation of the elements
Excessive incremental rotation of the elements in element set ErrElemExcessIncrementalRotation-Step1.
Error in job 1-hsh-exce-remesh: There are a total of 4 elements with excessive rotations
The ratio of deformation speed to wave speed in the elements in element set WarnElemDeformRateExceedsRatio-Step1 exceed the warning ratio

如 Node Set 的,

Some nodes involved in general contact have penetrated their
tracked faces by more than 50.000 percent of the typical element
dimension in the general contact domain, 4.58846E-04. Please check
the node set "InfoNodeDeepPenetFirst". Please make sure that these
nodes and their contacting faces have sufficient mass to allow the
code to calculate realistic contact penalties for enforcing the
contact constraint.

操作大同小异。©
