**Skew** mesh quality criterion reflects the angle between the lines
|
||
|
|
that join opposite sides of a quadrangle element or the greatest angle
|
||
|
|
between a median and a midline in a triangle element. This mesh quality
|
||
|
|
criterion can be applied to elements composed of 4 and 3 nodes
|
||
|
|
(quadrangles and triangles).

**To apply the Skew quality criterion to your mesh:**
|
||
|
|
|
||
|
|
|
||
|
|
#. Display your mesh in the viewer.
|
||
|
|
#. Choose **Controls > Face Controls > Skew** or click **"Skew"** button of the toolbar.

|
.. centered::
|
||
|
|
**"Skew" button**
|
||
|
|
|
||
|
|
|
||
|
|
Your mesh will be displayed in the viewer with its elements colored according to the applied mesh quality control criterion:
