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>

22 SALOME uses the convention of nodal connectivity of MED library elements. You
23 can consult the description of nodal connectivity of elements in the documentation on MED library or
24 <a href="http://www.code-aster.org/outils/med/html/connectivites.html">
27 <em>To add a node or an element to your mesh:</em>
29 <li>Select your mesh in the Object Browser or in the 3D viewer.</li>
31 <li>From the \b Modification menu choose the \b Add item, the
32 following associated sub-menu will appear:</li>
34 \image html image146.png
36 From this sub-menu select the type of element which you would like to add to your mesh.
38 \note All dialogs for new node or element adding to the mesh provide
39 the possibility to automatically add
40 a node or element to the specified group or to create it anew using
41 <b>Add to group</b> box, that allows choosing an existing group for
42 the created node or element or giving the name to a new group. By
43 default, the <b>Add to group</b> check box is switched off. If the user
44 switches this check box on, the combo box listing all currently
45 existing groups of the corresponding type becomes available. By
46 default, no group is selected. In this case, when the user presses
47 <b>Apply</b> or <b>Apply & Close</b> button, the warning message box
48 informs the user about the necessity to input new group name. The
49 combo box lists both \ref standalone_group "standalone groups"
50 and \ref group_on_geom "groups on geometry". If the user chooses a
51 group on geometry, he is warned and proposed to
52 \ref convert_to_standalone "convert this group to standalone".
53 If the user rejects conversion operation, it is cancelled and
54 a new node/element is not created!

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

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

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:

157 In this dialog box specify the nodes which will form your quadrangle
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:

164 \anchor adding_polygons_anchor
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.

203 In the Add Hexagonal Prism dialog box specify the nodes which will
204 form your hexagonal prism by selecting them in the 3D viewer with pressed Shift button and click

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:
