-<h1>Adding Quadratic Elements</h1>\r
-\r
-<p>MESH modules allows you to work with <span style="font-weight: bold;"><B>Quadratic \r
- Elements</B></span>.</p>\r
-\r
-<p>Quadratic Edge in not a straight but a broken line and can be defined \r
- by three points: first, middle and last. All more complex <span style="font-weight: bold;"><B>Quadratic \r
- Elements</B></span> differ from ordinary ones in that they consist of Quadratic \r
- Edges.</p>\r
-\r
-<p class=TODO\r
- style="font-family: 'Arial Black', sans-serif; font-style: italic;">To \r
- add a quadratic element to your mesh:</p>\r
-\r
-<p class="whs1">1. Select your mesh in the Object Browser \r
- or in the 3D viewer.</p>\r
-\r
-<p class="whs1">2. From the <span style="font-weight: bold;"><B>Modification \r
- </B></span>menu choose the <span style="font-weight: bold;"><B>Add </B></span>item \r
- and select one of the following: </p>\r
-\r
-<p class="whs1"><img src="image152.gif" width="148px" height="168px" border="0" class="img_whs2"></p>\r
-\r
-<p class="whs1">To create any <span style="font-weight: bold;"><B>Quadratic \r
- Element </B></span>specify the nodes which will form your triangle by selecting \r
- them in the 3D viewer with pressed Shift button. Their numbers will appear \r
- in the dialog box as <span style="font-weight: bold;"><B>Corner Nodes</B></span> \r
- (alternatively you can just input numbers in this field without selection).The \r
- edges formed by the corner nodes will appear in the table. To define the \r
- middle nodes for each edge double-click on the respective field and input \r
- the number of the node. All edges and the object formed by them will be \r
- displayed in the Object browser. When all edges are defined you will be \r
- able to click <span style="font-weight: bold;"><B>OK</B></span> or <span style="font-weight: bold;"><B>Apply</B></span> \r
- button to add the element to the mesh. </p>\r

-\r
-<p class="whs1"><span style="font-weight: bold;"><B>Reverse</B></span> \r
- button for Quadratic Edges switches the first and the last nodes. <span \r
- style="margin-left: 40px;">For all other elements it reverses the element. \r
