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 <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 switches 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 way to create 0D elements. It is possible to create
85 0D elements on all nodes of the selected mesh, sub-mesh, or a group of elements or nodes.
87 \image html dlg_0D_on_all_nodes.png
91 <li> The radio-buttons allow choosing the type of object to create 0D elements on.
93 <li><b> Mesh, sub-mesh, group </b> - this button allows selecting
94 a mesh, a sub-mesh or a group to create 0D elements on the nodes of its
95 elements. The name of the selected object is shown in the dialog. </li>
96 <li><b> Elements </b> - this button allows selecting elements in the
97 VTK viewer or typing their IDs in the dialog.</li>
98 <li><b> Nodes </b> - this button allows selecting nodes to create
99 0D elements on in the VTK viewer or typing their IDs in the dialog.</li>
101 <li><b> Set Filter </b> button allows selecting elements or nodes
102 by filtering mesh elements or nodes with different criteria
103 (see \ref filtering_elements "Filter usage").</li>
104 <li> Switching on <b>Add to group</b> check-box allows specifying the
105 name of the group to which all created or found 0D elements will be added. You can either select an existing group from
106 a drop-down list, or enter the name of the group to be created.</li>

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