-\n Revolution is used to build mesh elements of plus one
-dimension than the input ones. Boundary elements around generated
-mesh of plus one dimension are additionally created. All created
-elements can be automatically grouped. Revolution can be used to create
-a \ref extrusion_struct "structured mesh from scratch".
-See \ref extrusion_page page for general information on Revolution,
-which can be viewed as extrusion along a circular path.
-
-<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 will appear:
-

-
- </li>
-
- <li>In this dialog:
- <ul>
- <li>Use \a Selection button to specify what you are going to
- select at a given moment, \b Nodes, \b Edges or \b Faces.

-<center><em>"Selection" button</em></center>
- </li>
- <li>Specify \b Nodes, \b Edges and \b Faces, which will be revolved, by one
- of following means:
- <ul>
- <li><b>Select the whole mesh, sub-mesh or group</b> activating this
- check-box.</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>Node IDs</b>, <b>Edge
- IDs</b> and <b>Face IDs</b> fields. The selected elements will
- be highlighted in the viewer, if the mesh is shown there.</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>Specify the \b Axis of revolution:
- <ul>
- <li>Specify the coordinates of the start \b Point of the
- axis of revolution; either directly or by picking a node
- in the Viewer (selection of nodes is activated as you click
- the \a Selection button).</li>
- <li>Specify the \b Vector of the axis in either of three ways:
- <ul>
- <li>directly adjust vector components;</li>
- <li>click \a Selection button, choose <em>From Origin to
- selected Point</em> in the opened menu and pick a node
- in the Viewer; </li>
- <li>click \a Selection button, chose <em>Normal to
- selected Face</em> in the opened menu and pick a mesh
- face in the Viewer.</li>
- </ul></ul>
- </li>
- <li>Specify the \b Angle of revolution and the <b>Number of
- steps </b> of revolution,
- <ul>
- <li> <b>Angle by Step</b> - the elements are revolved by the
- specified angle at each step (i.e. for Angle=30 and Number of
- Steps=3, the elements will be extruded by 30 degrees twice for a
- total of 30*3=90)
-\image html revolutionsn2.png "Example of Revolution with Angle by Step. Angle=30 and Number of Steps=3"
- </li>
- <li> <b>Total Angle</b> - the elements are revolved 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=3,
- the elements will be revolved by 30/3=10 degrees twice for a
- total of 30).

- </li>
- </ul>
- </li>
- <li>Specify the \b Tolerance, which is used to detect nodes lying
- on the axis of revolution.
- </li>
- <li>Activate <b>Preview</b> check-box to see the result mesh in
- the viewer.
- </li>
- <li>If you activate <b>Generate Groups</b> check-box, the <em>result elements</em>
- created from <em>selected elements</em> contained in groups will be
- included into new groups named by pattern "<old group
- name>_rotated" and "<old group name>_top". For example if a
- selected quadrangle is included in \a g_Faces group (see figures
- below) then result hexahedra will be included in \a
- g_Faces_rotated group and a quadrangle created at the "top" of
- revolved mesh will be included in \a g_Faces_top group. <br>

- <p> This check-box is active only if there are some groups in the mesh.
- </li>
- </ul>
- </li>
-
- <li>Click \b Apply or <b> Apply and Close</b> button to confirm the
- operation.</li>
-</ol>
