|
|
|
|
\n Extrusion is used to build mesh elements of plus one
|
|
dimension than the input ones. Any node, segment or 2D element can be
|
|
extruded. Each type of elements has a corresponding type of extruded elements:
|
|
<table>
|
|
<tr><td><b>Extruded element</b></td><td><b> Result element </b></td></tr>
|
|
<tr><td>Node </td><td> Segment </td></tr>
|
|
<tr><td>Segment </td><td> Quadrilateral </td></tr>
|
|
<tr><td>Triangle </td><td> Pentahedron </td></tr>
|
|
<tr><td>Quadrilateral </td><td> Hexahedron </td></tr>
|
|
<tr><td>Polygon </td><td> Polyhedron </td></tr>
|
|
<tr><td>Hexagonal polygon </td><td> Hexagonal prism </td></tr>
|
|
</table>
|
|
|
|
<em>To use extrusion:</em>
|
|
<ol>
|
|
<li>From the \b Modification menu choose the \b Extrusion item or click
|
|
<em>"Extrusion"</em> button in the toolbar.

|
|
|

The following dialog common for line and planar elements will appear:

|
|
|
|
</li>
|
|
|
|
<li>In this dialog:
|
|
<ul>
|
|
<li>Select the type of elements which will be extruded (nodes, 1D or
|
|
2D elements).</li>
|
|
<li>Specify the IDs of the elements which will be extruded by one
|
|
following means:
|
|
<ul>
|
|
<li><b>Select the whole mesh, submesh or group</b> activating this
|
|
checkbox.</li>
|
|
<li>Choose mesh elements with the mouse in the 3D Viewer. It is
|
|
possible to select a whole area with a mouse frame.</li>
|
|
<li>Input the element IDs directly in <b>ID Elements</b>
|
|
field. The selected elements will be highlighted in the viewer.</li>
|
|
<li>Apply Filters. <b>Set filter</b> button allows to apply a
|
|
filter to the selection of elements. See more about filters in
|
|
the \ref filtering_elements "Selection filters" page.</li>
|
|
</ul>
|
|
</li>
|
|
<li>If the <b>Extrude to Distance</b> radio button is selected</li>
|
|
<ul>
|
|
<li>specify the distance at which the elements will be extruded.</li>
|
|
</ul>
|
|
<li>If the <b>Extrude Along Vector</b> radio button is selected</li>
|
|
<ul>
|
|
<li>specify the coordinates of the vector along which the elements
|
|
will be extruded, or select the face (the normal to the face will
|
|
define the vector),</li>
|
|
<li>specify the distance of extrusion along the vector.</li>
|
|
</ul>
|
|
<li>Specify the number of steps.</li>
|
|
<li>If you activate <b>Generate Groups</b> check-box, the <em>result elements</em>
|
|
created from <em>extruded elements</em> contained in groups will be
|
|
included into new groups named by pattern "<old group
|
|
name>_extruded" and "<old group name>_top". For example if an
|
|
extruded quadrangle is included in \a Group_1 group then result
|
|
hexahedra will be included in \a Group_1_extruded group and a
|
|
quadrangle created at the "top" of extruded mesh will
|
|
be included in \a Group_1_top group. <br>This check-box is active
|
|
only if there are some groups in the mesh.</li>
|
|
</ul>
|
|
|
|
<li>Click \b Apply or <b> Apply and Close</b> button to confirm the operation.</li>
|
|
</ol>
