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>

22 The convention of nodal connectivity of elements used in SALOME is
23 the MED library convention. You can consult the description of
24 nodal connectivity of elements in the documentation on MED library or
25 <a href="http://www.code-aster.org/outils/med/html/connectivites.html">
28 <em>To add a node or an element to your mesh:</em>
30 <li>Select your mesh in the Object Browser or in the 3D viewer.</li>
32 <li>From the \b Modification menu choose the \b Add item, the
33 following associated sub-menu will appear:</li>
35 \image html image152.png
37 From this sub-menu select the type of element which you would like to add to your mesh.
39 \note All dialogs for new node or element adding to the mesh provide
40 the possibility to automatically add
41 a node or element to the specified group or to create it anew using
42 <b>Add to group</b> box, that allows choosing an existing group for
43 the created node or element or giving the name to a new group. By
44 default, the <b>Add to group</b> check box is switched off. If the user
45 switches this check box on, the combo box listing all currently
46 existing groups of the corresponding type becomes available. By
47 default, no group is selected. In this case, when the user presses
48 <b>Apply</b> or <b>Apply & Close</b> button, the warning message box
49 informs the user about the necessity to input new group name. The
50 combo box lists groups of all the
51 \ref grouping_elements_page "three types": both
52 \ref standalone_group "standalone groups",
53 \ref group_on_filter "groups on filter", and
54 \ref group_on_geom "groups on geometry". If the user chooses a
55 group on geometry or on filter, he is warned and proposed to
56 convert this group to standalone.
57 If the user rejects conversion operation, it is cancelled and
58 a new node/element is not created!

80 <h2>Adding 0D elements</h2>
82 \image html add0delement.png
84 In this dialog box specify nodes which will form your 0D elements by
85 selecting them in the 3D viewer and click the \b Apply or
86 <b>Apply and Close</b> button. Your 0D elements will be created:
88 \image html add_0delement.png
90 \anchor adding_0delems_on_all_nodes_anchor
91 <h2>Making 0D elements on Element Nodes</h2>
93 There is another way to create 0D elements. It is possible to create
94 0D elements on all nodes of the selected mesh, sub-mesh, or a group of elements or nodes.
96 \image html dlg_0D_on_all_nodes.png
100 <li> The radio-buttons allow choosing the type of object to create 0D elements on.
102 <li><b> Mesh, sub-mesh, group </b> - this button allows selecting
103 a mesh, a sub-mesh or a group to create 0D elements on the nodes of its
104 elements. The name of the selected object is shown in the dialog. </li>
105 <li><b> Elements </b> - this button allows selecting elements in the
106 VTK viewer or typing their IDs in the dialog.</li>
107 <li><b> Nodes </b> - this button allows selecting nodes to create
108 0D elements on in the VTK viewer or typing their IDs in the dialog.</li>
110 <li><b> Set Filter </b> button allows selecting elements or nodes
111 by filtering mesh elements or nodes with different criteria
112 (see \ref filtering_elements "Filter usage").</li>
113 <li> Switching on <b>Add to group</b> check-box allows specifying the
114 name of the group to which all created or found 0D elements will be added. You can either select an existing group from
115 a drop-down list, or enter the name of the group to be created.</li>

120 <h2>Adding ball elements</h2>
122 \image html addball.png
124 In this dialog box specify the nodes, which will form your ball elements,
125 either by selecting them in the 3D viewer or by manually entering their IDs,
126 specify the ball diameter and click the \b Apply or <b>Apply and

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