\n The <b>Aspect Ratio 3D</b> mesh quality criterion calculates the same
|
|
parameter as the \ref aspect_ratio_page "Aspect ratio" criterion, but
|
|
it is applied to 3D mesh elements: tetrahedrons, pentahedrons,
|
|
hexahedrons, etc.
|
|
|
|
- The <b>Aspect Ratio</b> of a \b tetrahedron 3D element defined by
|
|
vertices {a,b,c,d } is calculated by the formula:
|
|

|
|
|
- Other element types like polyhedron, pentahedron and hexahedron use
|
|
the following formula:

<em>To apply the Aspect Ratio 3D quality criterion to your mesh:</em>
|
|
<ol>
|
|
<li>Display your mesh in the viewer.</li>
|
|
|
|
<li>Choose <b>Controls > Volume Controls > Aspect Ratio 3D</b> or click
|
|
<em>"Aspect Ratio 3D"</em> button of the toolbar.
|
|
|
|

<center><em>"Aspect Ratio 3D" button</em></center>
|
|
|
|
Your mesh will be displayed in the viewer with its elements colored
|
|
according to the applied mesh quality control criterion:
