The **Aspect Ratio** quality criterion for mesh elements reveals the degree of conformity of a mesh element to the regular element of its type (with all edges having the same length).
|
||
|
|
|
||
|
|
|
||
|
|
* The **Aspect Ratio** of a **triangle** 2D element consisting of 3 nodes is calculated by the formula:
|
||

|
||
|
|
:align: center
|
||
|
|
|
||
|
|
* The **Aspect Ratio** of a **quadrangle** 2D element consisting of 4 nodes is calculated using The Verdict Geometric Quality Library available within VTK. The calculation formula is:

:align: center
|
||
|
|
|

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

|

|
|
:align: center
|
||
|
|
|
||
|
|
.. centered::
|
||
|
|
Aspect Ratio button
|
||
|
|
|
||
|
|
Your mesh will be displayed in the viewer with its elements colored according to the applied mesh quality control criterion:

|
||

:align: center
