There is only one excessively distorted element

The elements contained in element set ErrElemExcessDistortion-Step1 have distorted excessively.

请问这种情况该如何处理，谢谢

对于“网格扭曲”的警告： 。red]excessively distorted element 。前面有提到。

第一步：采用二楼底下的方法用display查看“ ErrElemExcessDistortion-Step1 ”在模型的哪些部位，做到心中有数。

第二步：检查模型的网格质量： mesh步---verify----Analysis Check选取模型。。#0000ff]这种情况，一开始计算即出现“distorted element”的信息。。Besides：很多其他问题也会网格扭曲警告。比如，几何模型导入有误需要修补、单元类型选取错误、边界条件有误、材料属性错误、接触设置不合理、子程序错误等。

第三步：即使你的网格划分很好，如果变形过大，也会导致网格扭曲。然后修改网格划分，怒要出现红色，关键区域不要出现黄色。（当然最好是所有的网格都用structure划分，且都没有红色、黄色出现。网格质量就比较好。。#0000ff]这种情况，警告信息往往是在计算到一定步骤之后才出现“distorted element”。。 这种情况建议采用ALE等方式，此不详述，搜索论坛“网格重划”“ALE”等技术。

liuya118 发表于 2009-4-14 16:41 谢谢，此外我有一个模型可以正常算出来，但是我把此模型放大后在提交job的时候就出了错误，错误如下：Output request veeq is not available for this option 不知为何，谢谢。 [b]

liuya118 发表于 2009-4-17 21:48 请问版主，我在提交job之后，进入Abaqus/Explicit

Q-lp&O8}出现分析步 1, 帧 0 : 已输出到 ODB之后就再也没有下文了。 我的网格不多，计算也不复杂，而且没有出错的的提醒。 警告内容如下：

5 elements are distorted. Either the interior 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.

Boundary conditions are defined at the the nodes contained in node set

请问是什么原因？谢谢

你的模型警告信息虽多，但是就那么几类：

1 inelastic heat fraction and *specific heat are only used in an adiabatic analysis and a coupled temperature-displacement analysis

E.Y*t

z7?;2 Output request e is not available in a nonlinear step 这种前面已经说过，可以不管，只是通知性质的信息。

3 distorted element见上，四楼有详细说明。

4 “Boundary conditions............采用了位移加载，前面我也说过，不管.

F!u ?3Y0C:^

我推测问题出在1或者2 ，先按4楼方法检查扭曲网格，不行的话就是你的1nelastic heat fraction 的问题了，可就这个问题详述你的模型，重新发帖。 页: [1] 2 3 4
