/*! \page adding_nodes_and_elements_page Adding nodes and elements \n In MESH you can add to your mesh different elements such as: The convention of nodal connectivity of elements used in SALOME is the MED library convention. You can consult the description of nodal connectivity of elements in the documentation on MED library or \ref connectivity_page "here". To add a node or an element to your mesh:
  1. Select your mesh in the Object Browser or in the 3D viewer.
  2. From the \b Modification menu choose the \b Add item, the following associated sub-menu will appear:
  3. \image html image152.png From this sub-menu select the type of element which you would like to add to your mesh. \note All dialogs for new node or element adding to the mesh provide the possibility to automatically add a node or element to the specified group or to create it anew using Add to group box, that allows choosing an existing group for the created node or element or giving the name to a new group. By default, the Add to group check box is switched off. If the user switches this check box on, the combo box listing all currently existing groups of the corresponding type becomes available. By default, no group is selected. In this case, when the user presses Apply or Apply & Close button, the warning message box informs the user about the necessity to input new group name. The combo box lists groups of all the \ref grouping_elements_page "three types": both \ref standalone_group "standalone groups", \ref group_on_filter "groups on filter", and \ref group_on_geom "groups on geometry". If the user chooses a group on geometry or on filter, he is warned and proposed to convert this group to standalone. If the user rejects conversion operation, it is cancelled and a new node/element is not created!

Adding nodes

\image html addnode.png In this dialog box set coordinates for your node in the \b Coordinates set of fields and click the \b Apply or Apply and Close button. Your node will be created: \image html add_node.png
\anchor adding_0delems_anchor

Adding 0D elements

\image html add0delement.png In this dialog box specify nodes which will form your 0D elements by selecting them in the 3D viewer and click the \b Apply or Apply and Close button. Your 0D elements will be created: \image html add_0delement.png \anchor adding_0delems_on_all_nodes_anchor

Making 0D elements on Element Nodes

There is another way to create 0D elements. It is possible to create 0D elements on all nodes of the selected mesh, sub-mesh, or a group of elements or nodes. \image html dlg_0D_on_all_nodes.png In this dialog \anchor adding_balls_anchor

Adding ball elements

\image html addball.png In this dialog box specify the nodes, which will form your ball elements, either by selecting them in the 3D viewer or by manually entering their IDs, specify the ball diameter and click the \b Apply or Apply and Close button. \image html add_ball.png
\anchor adding_edges_anchor

Adding edges

\image html addedge.png In this dialog box specify the nodes which will form your edge by selecting them in the 3D viewer with pressed Shift button and click the \b Apply or Apply and Close button. Your edge will be created: \image html add_edge.png
\anchor adding_triangles_anchor

Adding triangles

\image html addtriangle.png In this dialog box specify the nodes which will form your triangle by selecting them in the 3D viewer with pressed Shift button and click the \b Apply or Apply and Close button. Your triangle will be created: \image html add_triangle.png
\anchor adding_quadrangles_anchor

Adding quadrangles

\image html addquadrangle.png In this dialog box specify the nodes which will form your quadrangle by selecting them in the 3D viewer with pressed Shift button and click the \b Apply or Apply and Close button. Your quadrangle will be created: \image html add_quadrangle.png
\anchor adding_polygons_anchor

Adding polygons

\image html addpolygon.png In this dialog box specify the nodes which will form your polygon by selecting them in the 3D viewer with pressed Shift button and click the \b Apply or Apply and Close button. \image html add_polygone.png
\anchor adding_tetrahedrons_anchor

Adding tetrahedrons

\image html addtetrahedron.png In this dialog box specify the nodes which will form your tetrahedron by selecting them in the 3D viewer with pressed Shift button and click the \b Apply or Apply and Close button. Your tetrahedron will be created: \image html image70.jpg
\anchor adding_hexahedrons_anchor

Adding hexahedrons

\image html addhexahedron.png In this dialog box specify the nodes which will form your hexahedron by selecting them in the 3D viewer with pressed Shift button and click the \b Apply or Apply and Close button. Your hexahedron will be created: \image html image71.jpg
\anchor adding_octahedrons_anchor

Adding hexagonal prism

In the Add Hexagonal Prism dialog box specify the nodes which will form your hexagonal prism by selecting them in the 3D viewer with pressed Shift button and click the \b Apply or Apply and Close button. Your hexagonal prism will be created: \image html image_octa12.png
\anchor adding_polyhedrons_anchor

Adding polyhedrons

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