\n \b Warping indicates that a face is not planar and is applied only to
|
|
2D elements with 4 nodes. This quality control criterion is based on a
|
|
projection plane created by:
|
|
<ol>
|
|
<li>bisecting the four element edges,</li>
|
|
<li>creating a point on the plane at the vector average of the
|
|
corners, where the x-axis extends from the point to the bisector on
|
|
edge 2.</li>
|
|
</ol>
|
|
The plane normal is in the direction of the cross product of the
|
|
x-axis and the vector from the origin to the bisector of edge 3. Every
|
|
corner of the quad will then be a distance ?h? from the plane. The
|
|
length of each half edge is measured and the shortest length is
|
|
assigned ?l?. The warp angle is the arcsine of the ratio of the
|
|
projection height ?h? to the half edge length ?l?.
|
|
|
|
<em>To apply the Warping quality criterion to your mesh:</em>
|
|
<ol>
|
|
<li>Display your mesh in the viewer.</li>
|
|
|
|
<li>Choose <b>Controls > Face Controls > Warping Angle</b> or click
|
|
<em>"Warping angle"</em> button of the toolbar.

|
|
|
|
Your mesh will be displayed in the viewer with its elements colored
|
|
according to the applied mesh quality control criterion:
