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 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 \ref connectivity_page "here".
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 image152.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 groups of all the
50 \ref grouping_elements_page "three types": both
51 \ref standalone_group "standalone groups",
52 \ref group_on_filter "groups on filter", and
53 \ref group_on_geom "groups on geometry". If the user chooses a
54 group on geometry or on filter, he is warned and proposed to
55 convert this group to standalone.
56 If the user rejects conversion operation, it is cancelled and
57 a new node/element is not created!

79 <h2>Adding 0D elements</h2>
81 \image html add0delement.png
83 In this dialog box specify nodes which will form your 0D elements by
84 selecting them in the 3D viewer and click the \b Apply or
85 <b>Apply and Close</b> button. Your 0D elements will be created:

89 \anchor adding_0delems_on_all_nodes_anchor
90 <h2>Making 0D elements on Element Nodes</h2>
92 There is another way to create 0D elements. It is possible to create
93 0D elements on all nodes of the selected mesh, sub-mesh, or a group of elements or nodes.
95 \image html dlg_0D_on_all_nodes.png
99 <li> The radio-buttons allow choosing the type of object to create 0D elements on.
101 <li><b> Mesh, sub-mesh, group </b> - this button allows selecting
102 a mesh, a sub-mesh or a group to create 0D elements on the nodes of its
103 elements. The name of the selected object is shown in the dialog. </li>
104 <li><b> Elements </b> - this button allows selecting elements in the
105 VTK viewer or typing their IDs in the dialog.</li>
106 <li><b> Nodes </b> - this button allows selecting nodes to create
107 0D elements on in the VTK viewer or typing their IDs in the dialog.</li>
109 <li><b> Set Filter </b> button allows selecting elements or nodes
110 by filtering mesh elements or nodes with different criteria
111 (see \ref filtering_elements "Filter usage").</li>
112 <li> Switching on <b>Add to group</b> check-box allows specifying the
113 name of the group to which all created or found (existing) 0D elements will
114 be added. You can either select an existing group from a drop-down
115 list, or enter the name of the group to be created. If a selected
116 existing \ref grouping_elements_page "group" is not Standalone
117 (Group On Geometry or Group On Filter) it will be converted to
119 \warning If <b>Add to group</b> is activated it has to be filled in.

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

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