\page revolution_page Revolution
|
|
|
|
\n Revolution is a type of surface meshing by generation from
|
|
discretized lines. It is used to build mesh elements of plus one
|
|
dimension than the swept ones. Each swept 1D element produces one or
|
|
more quadrangles (or triangles if one node of a rotated element lays
|
|
on the revolution axis).
|
|
|
|
<em>To apply revolution:</em>
|
|
<ol>
|
|
<li>From the \b Modification menu choose the \b Revolution item or click
|
|
<em>"Revolution"</em> button in the toolbar.
|
|
|
|

|
|
<center><em>"Revolution" button</em></center>
|
|
|
|
The following dialog box shall appear:

|
|
</li>
|
|
|
|
<li>
|
|
In this dialog box you should specify:
|
|
<ul>
|
|
<li>the type of elements which will be extruded (1D or 2D),</li>
|
|
<li>specify the IDs of the elements which will be revolved
|
|
<ul>
|
|
<li>Check on <b>Select the whole mesh, submesh or group</b> option
|
|
<li>Choosing them manually with the mouse in the 3D Viewer. You can
|
|
click on an element in the 3D viewer and it will be highlighted</li>
|
|
<li>Applying Filters. The <b>Set filter</b> button allows to apply a
|
|
definite filter to selection of the elements. See more
|
|
about filters on the
|
|
\ref selection_filter_library_page "Selection filter library" page.</li>
|
|
</ul>
|
|
</li>
|
|
<li>specify the axis (point and vector) around which the elements will
|
|
be revolved,</li>
|
|
<li>angle of rotation and number of steps,</li>
|
|
<ul> <li> Angle by Step - the elements are extruded by the specified angle at each step (i.e. for Angle=30 and Number of Steps=2, the elements will be extruded
|
|
by 30 degrees twice for a total of 30*2=60)</li>
|
|
|
|
\image html revolutionsn2.png "Example of Revolution with Angle by Step"
|
|
|
|
<li> Total Angle - the elements are extruded by the specified angle only once and the number of steps defines the number of iterations
|
|
(i.e.for Angle=30 and Number of Steps=2, the elements will be extruded by 30/2=15 degrees twice for a total of 30). </li>

</ul>

|
|
<li> <b>Preview</b> checkbox allows showing the results of parameter-setting in the viewer </li>
|
|
<li> <b>Generate Groups</b> checkbox allows copying the groups of
|
|
elements of the source mesh to the newly created one. </li>
|
|
</li>
|
|
|
|
<li>Click the \b Apply or \b OK button.</li>
