Allowable Edge and Face Angles
The following diagram illustrates edge and face angles:

Minimum and Maximum Angles
The angle between any two adjacent element edges or faces must be equal to or greater than 0  and less than 179 , unless they are geometry-constrained angles. When AutoGEM is creating elements, edge and face angles should be between 5  and 175 .
Angles less than 5  or greater than 175  can affect run time and results. For some models, angles less than 5  and greater than 175  may be useful for the following purposes:
•        creating elements in a difficult area
•        decreasing the total number of elements
•        helping AutoGEM to finish creating elements
When you first switch from creating to editing mode, Mechanica checks that the creation edge and face angles are between 5  and 175  and warns you if the angles are not in this range. Select Accept to keep the values you selected for the angles. Select Cancel to change the creation limits back to the previous limits.



This option enables you to enter the maximum subtended edge angle that you want AutoGEM to use when it creates or edits elements.

During element creation, the value of this item cannot exceed 100  . The default for creating elements is 95 .
The default limit for editing is 100  . You cannot exceed the editing limit.
If you enter a value for the edge angle that is not within the range allowed for that mode, Mechanica prompts you to reenter a value within the proper range


This option enables you to enter the maximum aspect ratio that you want AutoGEM to allow when it creates or edits elements.
We recommend that you keep the default value for this field and address your element count through the Allowable Angles field instead. If you lower the Max Aspect Ratio setting, you may experience slower performance and AutoGEM may create inappropriate element concentrations.
The Mechanica guideline is that the aspect ratio of a solid face's length to its width and a shell's length to its width should be no greater than 30 to 1. The guideline for 2D plates and 2D solids is the same as for shells.
The default aspect ratio for creating is 30; the minimum value is 2. You should not use an aspect ratio higher than 30 for areas of your model that have high stress or flux gradients, or for areas of your model where you are especially interested in the results.
The default aspect ratio for editing is 100.

不好翻译啊，好多词用的太专业了。简单写了一下。你看一下！！！

谢谢了
真是英语的高手
听说proe5.0的全部是中文版的
估计没有人在对这个感兴趣了

不错，能分享个模型就好了
