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>
14 <li>Select your mesh in the Object Browser or in the 3D viewer.</li>
16 <li>From the \b Modification menu choose the \b Add item and select

21 \note All dialogs intended for adding quadratic elements to mesh provide a possibility
22 to add these elements to the specified group (or to create the group if it doesn't exist).
23 <b>Add to group</b> box allows to choose an existing group for created element or
24 to specify a name for new group.
26 To create any <b>Quadratic Element</b> specify the nodes which will form your
27 triangle by selecting them in the 3D viewer with pressed Shift
28 button. Their numbers will appear in the dialog box as <b>Corner Nodes</b>
29 (alternatively you can just input numbers in this field without
30 selection).The edges formed by the corner nodes will appear in the
31 table. To define the middle nodes for each edge double-click on the
32 respective field and input the number of the node. All edges and the
33 object formed by them will be displayed in the Object browser. When
34 all edges are defined you will be able to click \b Apply or <b>Apply and Close</b> button to
35 add the element to the mesh.
39 \b Reverse button for Quadratic Edges switches the first and the last
40 nodes. For all other elements it reverses the element.
