5 \n In MESH you can add to your mesh different elements such as:
8 <li>\ref adding_nodes_anchor "Nodes"</li>
9 <li>\ref adding_0delems_anchor "0D Elements"</li>
10 <li>\ref adding_0delems_on_all_nodes_anchor "0D elements on Element Nodes"</li>
11 <li>\ref adding_balls_anchor "Ball Elements"</li>
12 <li>\ref adding_edges_anchor "Edges"</li>
13 <li>\ref adding_triangles_anchor "Triangles"</li>
14 <li>\ref adding_quadrangles_anchor "Quadrangles"</li>
15 <li>\ref adding_polygons_anchor "Polygons"</li>
16 <li>\ref adding_tetrahedrons_anchor "Tetrahedrons"</li>
17 <li>\ref adding_hexahedrons_anchor "Hexahedrons"</li>
18 <li>\ref adding_octahedrons_anchor "Hexagonal prism"</li>
19 <li>\ref adding_polyhedrons_anchor "Polyhedrons"</li>
22 <em>To add a node or an element to your mesh:</em>
24 <li>Select your mesh in the Object Browser or in the 3D viewer.</li>
26 <li>From the \b Modification menu choose the \b Add item, the
27 following associated sub-menu will appear:</li>
29 \image html image146.png
31 From this sub-menu select the type of element which you would like to add to your mesh.
33 \note All dialogs for new node or element adding to the mesh provide
34 the possibility to automatically add
35 a node or element to the specified group or to create it anew using
36 <b>Add to group</b> box, that allows choosing an existing group for
37 the created node or element or giving the name to a new group. By
38 default, the <b>Add to group</b> check box is switched off. If the user
39 swiches this check box on, the combo box listing all currently
40 existing groups of the corresponding type becomes available. By
41 default, no group is selected. In this case, when the user presses
42 <b>Apply</b> or <b>Apply & Close</b> button, the warning message box
43 informs the user about the necessity to input new group name. The
44 combo box lists both \ref standalone_group "standalone groups"
45 and \ref group_on_geom "groups on geometry". If the user chooses a
46 group on geometry, he is warned and proposed to
47 \ref convert_to_standalone "convert this group to standalone".
48 If the user rejects conversion operation, it is cancelled and
49 a new node/element is not created!

71 <h2>Adding 0D elements</h2>
73 \image html add0delement.png
75 In this dialog box specify nodes which will form your 0d elements by
76 selecting them in the 3D viewer and click the \b Apply or
77 <b>Apply and Close</b> button. Your 0D elements will be created:

81 \anchor adding_0delems_on_all_nodes_anchor
82 <h2>Making 0D elements on Element Nodes</h2>
84 There is another dialog which lets you create 0D elements. It creates
85 0D elements on all nodes of selected elements or nodes, where no 0D
86 elements are yet present.
88 \image html dlg_0D_on_all_nodes.png
92 <li> Click a radio-button to choose a type of object on whose nodes you
93 want to create 0D elements.
95 <li><b> Mesh, sub-mesh, group </b> This button allows you selecting either
96 a mesh, sub-mesh or group to create 0D elements on nodes of their
97 elements. A name of selected object is shown in the dialog. </li>
98 <li><b> Elements </b> This button allows you selecting elements either in the
99 VTK viewer or typing their IDs in a field of dialog.</li>
100 <li><b> Nodes </b> This button allows you selecting nodes to create
101 0D elements on them either in the VTK viewer or typing their IDs
102 in a field of dialog.</li>
104 <li><b> Set Filter </b> button allows you selecting elements or nodes
105 by filtering elements or nodes of the mesh with different criteria
106 (see \ref filtering_elements "Filter usage" on how to set up selection
108 <li> Switching on <b>Add to group</b> check-box allows you specifying a
109 name of a group to add all 0D elements created or found on the
110 selected element nodes. You can either select an existing group from
111 a drop-down list, or enter a name of a group to create.</li>

116 <h2>Adding ball elements</h2>
118 \image html addball.png
120 In this dialog box specify nodes which will form your ball elements
121 either by selecting them in the 3D viewer or by manual entering their IDs,
122 specify the ball diameter and click the \b Apply or <b>Apply and
123 Close</b> button. Your ball elements with an equal diameter will be created:

129 <h2>Adding edges</h2>
131 \image html addedge.png
133 In this dialog box specify the nodes which will form your edge by
134 selecting them in the 3D viewer with pressed Shift button and click
135 the \b Apply or <b>Apply and Close</b> button. Your edge will be created:

158 by selecting them in the 3D viewer with pressed Shift button and click
159 the \b Apply or <b>Apply and Close</b> button. Your quadrangle will be created:

165 <h2>Adding polygons</h2>
167 \image html addpolygon.png
169 In this dialog box specify the nodes which will form your polygon by
170 selecting them in the 3D viewer with pressed Shift button and click
171 the \b Apply or <b>Apply and Close</b> button.

211 <h2>Adding polyhedrons</h2>
213 \image html a-createpolyhedralvolume.png
215 There are two different ways to add polyhedral volumes.
216 \n If you select \b Node as <b>Elements Type</b> you will specify the
217 nodes which will form the faces of your polyhedron by selecting the
218 nodes in the 3D viewer with pressed Shift button and clicking the \b
219 Add button to add the face in the list of Faces by Nodes, which will
220 form your polyhedron. Note, that it could be very useful to toggle
221 Polyhedron Preview checkbox to see the results of your selection.
222 \n The second way is somewhat simpler, however, there are cases when
223 it does not provide you with the necessary level of precision. If you
224 select \b Face as <b>Elements Type</b>, you will be able to select the faces
225 which will form your polyhedron in the 3D viewer with pressed Shift
226 button. If you've managed to obtain the necessary result, click the
227 \b Apply or <b>Apply and Close</b> button. Your polyhedron will be created:
