\n MESH modules allows you to work with <b>Quadratic Elements</b>.
|
|
|
|
Quadratic Edge is not a straight but a broken line and can be defined
|
|
by three points: first, middle and last. All more complex \b Quadratic
|
|
\b Elements differ from ordinary ones in that they consist of Quadratic
|
|
Edges.
|
|
|
|
<em>To add a quadratic element to your mesh:</em>
|
|
<ol>
|
|
<li>Select your mesh in the Object Browser or in the 3D viewer.</li>
|
|
|
|
<li>From the \b Modification menu choose the \b Add item and select
|
|
one of the following:

|
To create any <b>Quadratic Element</b> specify the nodes which will form your
|
|
triangle by selecting them in the 3D viewer with pressed Shift
|
|
button. Their numbers will appear in the dialog box as <b>Corner Nodes</b>
|
|
(alternatively you can just input numbers in this field without
|
|
selection).The edges formed by the corner nodes will appear in the
|
|
table. To define the middle nodes for each edge double-click on the
|
|
respective field and input the number of the node. All edges and the
|
|
object formed by them will be displayed in the Object browser. When
|
|
all edges are defined you will be able to click \b OK or \b Apply button to
|
|
add the element to the mesh.

\b Reverse button for Quadratic Edges switches the first and the last
|
|
nodes. For all other elements it reverses the element.
