3 \page modifying_meshes_page Modifying meshes
5 Salome provides a vast specter of mesh modification and
6 transformation operations, giving the possibility to:
9 <li>\subpage adding_nodes_and_elements_page "Add" mesh elements from
10 nodes to polyhedrons at an arbitrary place in the mesh.</li>
11 <li>\subpage adding_quadratic_elements_page "Add quadratic" mesh
12 elements from quadratic segments to quadratic hexahedrons at an
13 arbitrary place in the mesh.</li>
14 <li>\subpage removing_nodes_and_elements_page "Remove" any existing
15 mesh elements and nodes.</li>
16 <li>\subpage translation_page "Translate" in the indicated direction
17 the mesh or some of its elements.</li>
18 <li>\subpage rotation_page "Rotate" by the indicated axis and angle
19 the mesh or some of its elements.</li>
20 <li>\subpage scale_page "Scale" the mesh or some of its elements.</li>
21 <li>\subpage symmetry_page "Mirror" the mesh through a point, a vector
22 or a plane of symmetry.</li>
23 <li>\subpage double_nodes_page "Duplicate nodes or/and Elements".
24 Duplication of nodes can be useful to emulate a crack in the
26 <li>Unite meshes by \subpage sewing_meshes_page "sewing" free borders,
27 border to side or side elements.</li>
28 <li>\subpage merging_nodes_page "Merge Nodes", coincident within the
29 indicated tolerance.</li>
30 <li>\subpage merging_elements_page "Merge Elements" based on the same
32 <li>\subpage mesh_through_point_page "Move Nodes" to an arbitrary
33 location with consequent transformation of all adjacent
35 <li>\subpage diagonal_inversion_of_elements_page "Invert an edge"
36 between neighboring triangles.</li>
37 <li>\subpage uniting_two_triangles_page "Unite two triangles".</li>
38 <li>\subpage uniting_set_of_triangles_page "Unite several adjacent triangles".</li>
39 <li>\subpage changing_orientation_of_elements_page "Change orientation"
40 of the selected elements.</li>
41 <li>\subpage reorient_faces_page "Orient faces" by several means.</li>
42 <li>\subpage cutting_quadrangles_page "Cut a quadrangle" into two
44 <li>\subpage split_to_tetra_page "Split" volumic elements into
45 tetrahedra or prisms.</li>
46 <li>\subpage smoothing_page "Smooth" elements, reducung distortions in
47 them by adjusting the locations of nodes.</li>
48 <li>Create an \subpage extrusion_page "extrusion" along a vector or by
49 normal to a discretized surface.</li>
50 <li>Create an \subpage extrusion_along_path_page "extrusion along a path".</li>
51 <li>Create elements by \subpage revolution_page "revolution" of the
52 selected nodes and elements.</li>
53 <li>Apply \subpage pattern_mapping_page "pattern mapping".</li>
54 <li>\subpage convert_to_from_quadratic_mesh_page "Convert linear mesh to quadratic",
56 <li>\subpage make_2dmesh_from_3d_page "Generate boundary elements".</li>
57 <li>\subpage generate_flat_elements_page "Generate flat elements on group boundaries or on faces".</li>
58 <li>\subpage cut_mesh_by_plane_page "Cut a tetrahedron mesh by a plane".</li>
61 \note It is possible to \ref edit_anchor "modify the mesh" of a lower
62 dimension before generation of the mesh of a higher dimension.
66 \note It is possible to use the variables defined in the SALOME \b NoteBook
67 to specify the numerical parameters used for modification of any object.
