\page adding_nodes_and_elements_page Adding nodes and elements
\n In MESH you can add to your mesh different elements such as:
- \ref adding_nodes_anchor "Nodes"
- \ref adding_0delems_anchor "0D Elements"
- \ref adding_0delems_on_all_nodes_anchor "0D elements on Element Nodes"
- \ref adding_balls_anchor "Ball Elements"
- \ref adding_edges_anchor "Edges"
- \ref adding_triangles_anchor "Triangles"
- \ref adding_quadrangles_anchor "Quadrangles"
- \ref adding_polygons_anchor "Polygons"
- \ref adding_tetrahedrons_anchor "Tetrahedrons"
- \ref adding_hexahedrons_anchor "Hexahedrons"
- \ref adding_octahedrons_anchor "Hexagonal prism"
- \ref adding_polyhedrons_anchor "Polyhedrons"
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:
- Select your mesh in the Object Browser or in the 3D viewer.
- From the \b Modification menu choose the \b Add item, the
following associated sub-menu will appear:
\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!

\ref tui_adding_nodes_and_elements "Adding Nodes and Elements"
operations.
\anchor adding_nodes_anchor
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
- The radio-buttons allow choosing the type of object to create 0D elements on.
- Mesh, sub-mesh, group - this button allows selecting
a mesh, a sub-mesh or a group to create 0D elements on the nodes of its
elements. The name of the selected object is shown in the dialog.
- Elements - this button allows selecting elements in the
VTK viewer or typing their IDs in the dialog.
- Nodes - this button allows selecting nodes to create
0D elements on in the VTK viewer or typing their IDs in the dialog.
- Set Filter button allows selecting elements or nodes
by filtering mesh elements or nodes with different criteria
(see \ref filtering_elements "Filter usage").
- Switching on Add to group check-box allows specifying the
name of the group to which all created or found (existing) 0D elements will
be added. You can either select an existing group from a drop-down
list, or enter the name of the group to be created. If a selected
existing \ref grouping_elements_page "group" is not Standalone
(Group On Geometry or Group On Filter) it will be converted to
Standalone.
\warning If Add to group is activated it has to be filled in.
\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:
