|
|
|
|
\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 common for line and planar elements will appear:
|
|
|
|

|
|
|
|
</li>
|
|
|
|
<li>
|
|
In this dialog 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><b>Select the whole mesh, submesh or group</b> activating this
|
|
checkbox; or</li>
|
|
<li>choose mesh elements with the mouse in the 3D Viewer. It is
|
|
possible to select a whole area with a mouse frame; or</li>
|
|
<li>input the element IDs directly in <b>ID Elements</b> field. The selected elements will be highlighted in the
|
|
viewer; or</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 selection_filter_library_page "Selection filter library" page.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>specify the axis of revolution:
|
|
<ul>
|
|
<li>specify the cooordinates of the start \b Point of the vector of revolution;</li>
|
|
<li>specify the \b Vector of revolution through the coordinates of its
|
|
end point with respect to the coordinates of the start
|
|
point. Alternatively, it is possible to specify the vector through the
|
|
normal to the selected face.</li>
|
|
</ul>
|
|
</li>
|
|
|
|
<li>specify the angle of revolution and the number of revolution 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>
|
|
|
|
<li>specify the tolerance for the operation</li>
|
|
|
|
<li>activate <b>Preview</b> checkbox to show the parameter-setting in the viewer </li>
|
|
<li>activate <b>Generate Groups</b> checkbox to copy the groups of
|
|
elements of the source mesh to the newly created one. </li>
|
|
</li>
|
|
</ul>
|
|
|
|
<li>Click \b Apply or <b> Apply and Close</b> button to confirm the
|
|
operation.</li>
