\page modifying_meshes_page Modifying meshes

Salome provides an extremely vast specter of mesh modification and
transformation operations, giving the possibility to:

<ul>
<li>\subpage adding_nodes_and_elements_page "Add" mesh elements from
nodes to polyhedrons at an arbitrary place in the mesh.</li>
<li>\subpage adding_quadratic_elements_page "Add quadratic" mesh
elements (used in quadratic meshes) from quadratic nodes to quadratic polyhedrons at an arbitrary place in the mesh.</li>
<li>\subpage removing_nodes_and_elements_page "Remove" any existing
mesh elements.</li>
<li>\subpage renumbering_nodes_and_elements_page "Renumber" nodes and
elements of the mesh.</li>
<li>\subpage translation_page "Translate" in the indicated direction the mesh or some of
its elements.</li>
<li>\subpage rotation_page "Rotate" by the indicated axis and angle
the mesh or some of its elements.</li>
<li>\subpage scale_page "Scale Transform" the mesh or some of its elements.</li>
<li>Create a \subpage symmetry_page "symmetrical copy" of the mesh
through a point or a vector of symmetry.</li>
<li>Unite meshes by \subpage sewing_meshes_page "sewing" free borders,
conform free borders, border to side or side elements.</li>
<li>\subpage merging_nodes_page "Merge Notes", considered coincident
within the indicated tolerance.</li>
<li>\subpage merging_elements_page "Merge Elements", considered coincident
within the indicated tolerance.</li>
<li>\subpage moving_nodes_page "Move Nodes" to an arbitrary location
with consequent transformation of all adjacent elements and edges.</li>
<li>\subpage mesh_through_point_page "Make node at a point", existing
or created anew.</li>
<li>\subpage diagonal_inversion_of_elements_page "Invert an edge" between neighboring triangles.</li>
<li>\subpage uniting_two_triangles_page "Unite two triangles".</li>
<li>\subpage uniting_set_of_triangles_page "Unite several adjacent triangles".</li>
<li>\subpage changing_orientation_of_elements_page "Change orientation"
 of the selected elements.</li>
<li>\subpage cutting_quadrangles_page "Cut a quadrangle" into two triangles.</li>
<li>\subpage split_to_tetra_page "Split" volumic elements into tetrahedra.</li>
<li>\subpage smoothing_page "Smooth" elements, reducung distortions in
them by adjusting the locations of element corners.</li>
<li>Create an \subpage extrusion_page "extrusion" along a vector.</li>
<li>Create an \subpage extrusion_along_path_page "extrusion along a path".</li>
<li>Create an edge or a surface by \subpage revolution_page "revolution"
of the selected node or edge.</li>
<li>Apply \subpage pattern_mapping_page "pattern mapping".</li>
<li>\subpage convert_to_from_quadratic_mesh_page "Convert regular mesh to quadratic", 
or vice versa.</li>
<li>\subpage make_2dmesh_from_3d_page "Create 2D mesh from 3D".</li>

</ul>

\note It is possible to use the variables defined in the SALOME \b NoteBook
 to specify the numerical parameters used for modification of any object.
