\n The <b>Aspect Ratio</b> 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 <b>Aspect Ratio</b> of a \b triangle 2D element consisting of 3
|
|
nodes is calculated by the formula:

|
|
- The <b>Aspect Ratio</b> of a \b quadrangle 2D element consisting of
|
|
4 nodes is the worst (i.e. the greatest) value from all triangles
|
|
which can be built taking three nodes of the quadrangle. There are
|
|
four triangles to consider:

|
<ol>
|
|
<li>Display your mesh in the viewer.</li>
|
|
|
|
<li>Choose <b>Controls > Aspect Ratio</b> or click <em>"Aspect

Your mesh will be displayed in the viewer with its elements colored
|
