5 \n MESH modules allows you to work with <b>Quadratic Elements</b>.
7 Quadratic Edge is not a straight but a broken line and can be defined
8 by three points: first, middle and last. All more complex \b Quadratic
9 \b Elements differ from ordinary ones in that they consist of Quadratic
12 <em>To add a quadratic element to your mesh:</em>

21 To create any <b>Quadratic Element</b> specify the nodes which will form your
22 triangle by selecting them in the 3D viewer with pressed Shift
23 button. Their numbers will appear in the dialog box as <b>Corner Nodes</b>
24 (alternatively you can just input numbers in this field without
25 selection).The edges formed by the corner nodes will appear in the
26 table. To define the middle nodes for each edge double-click on the
27 respective field and input the number of the node. All edges and the
28 object formed by them will be displayed in the Object browser. When
29 all edges are defined you will be able to click \b Apply or <b>Apply and Close</b> button to
30 add the element to the mesh.
34 \b Reverse button for Quadratic Edges switches the first and the last
35 nodes. For all other elements it reverses the element.
