5 \n Revolution is used to build mesh elements of plus one
6 dimension than the input ones. Boundary elements around generated
7 mesh of plus one dimension are additionally created. All created
8 elements can be automatically grouped. Revolution can be used to create
9 a \ref extrusion_struct "structured mesh from scratch".
10 See \ref extrusion_page page for general information on Revolution
11 which can be viewed as extrusion along a circular path.
13 <em>To apply revolution:</em>
15 <li>From the \b Modification menu choose the \b Revolution item or click
16 <em>"Revolution"</em> button in the toolbar.
18 \image html image92.png
19 <center><em>"Revolution" button</em></center>
21 The following dialog will appear:
23 \image html revolution1.png
29 <li>Use \a Selection button to specify what you are going to
30 select at a given moment, \b Nodes, \b Edges or \b Faces.
31 \image html image120.png
32 <center><em>"Selection" button</em></center>
34 <li>Specify \b Nodes, \b Edges and \b Faces, which will be revolved, by one
37 <li><b>Select the whole mesh, sub-mesh or group</b> activating this
39 <li>Choose mesh elements with the mouse in the 3D Viewer. It is
40 possible to select a whole area with a mouse frame.</li>
41 <li>Input the element IDs directly in <b>Node IDs</b>, <b>Edge
42 IDs</b> and <b>Face IDs</b> fields. The selected elements will
43 be highlighted in the viewer, if the mesh is shown there.</li>
44 <li>Apply Filters. <b>Set filter</b> button allows to apply a
45 filter to the selection of elements. See more about filters in
46 the \ref filtering_elements "Selection filters" page.</li>
49 <li>Specify the \b Axis of revolution:
51 <li>Specify the coordinates of the start \b Point of the
52 axis of revolution; either directly or by picking a node
53 in the Viewer (selection of nodes is activated as you click
54 the \a Selection button).</li>
55 <li>Specify the \b Vector of the axis in either of three ways:
57 <li>directly adjust vector components;</li>
58 <li>click \a Selection button, choose <em>From Origin to
59 selected Point</em> in the opened menu and pick a node
61 <li>click \a Selection button, chose <em>Normal to
62 selected Face</em> in the opened menu and pick a mesh
63 face in the Viewer.</li>
66 <li>Specify the \b Angle of revolution and the <b>Number of
67 steps </b> of revolution,
69 <li> <b>Angle by Step</b> - the elements are revolved by the
70 specified angle at each step (i.e. for Angle=30 and Number of
71 Steps=3, the elements will be extruded by 30 degrees twice for a
73 \image html revolutionsn2.png "Example of Revolution with Angle by Step. Angle=30 and Number of Steps=3"
75 <li> <b>Total Angle</b> - the elements are revolved by the
76 specified angle only once and the number of steps defines the
77 number of iterations (i.e. for Angle=30 and Number of Steps=3,
78 the elements will be revolved by 30/3=10 degrees twice for a
80 \image html revolutionsn1.png "Example of Revolution with Total Angle. Angle=30 and Number of Steps=3"
84 <li>Specify the \b Tolerance, which is used to detect nodes lying
85 on the axis of revolution.
87 <li>Activate <b>Preview</b> check-box to see the result mesh in
90 <li>If you activate <b>Generate Groups</b> check-box, the <em>result elements</em>
91 created from <em>selected elements</em> contained in groups will be
92 included into new groups named by pattern "<old group
93 name>_rotated" and "<old group name>_top". For example if a
94 selected quadrangle is included in \a g_Faces group (see figures
95 below) then result hexahedra will be included in \a
96 g_Faces_rotated group and a quadrangle created at the "top" of
97 revolved mesh will be included in \a g_Faces_top group. <br>

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