3 \page modifying_meshes_page Modifying meshes
5 Salome provides an extremely 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 (used in quadratic meshes) from quadratic nodes to quadratic polyhedrons at an arbitrary place in the mesh.</li>
13 <li>\subpage removing_nodes_and_elements_page "Remove" any existing
15 <li>\subpage translation_page "Translate" in the indicated direction the mesh or some of
17 <li>\subpage rotation_page "Rotate" by the indicated axis and angle
18 the mesh or some of its elements.</li>
19 <li>\subpage scale_page "Scale" the mesh or some of its
21 <li>\subpage symmetry_page "Mirror" the mesh
22 through a point or a vector of symmetry.</li>
23 <li>\subpage double_nodes_page "Duplicate nodes or/and Elements". Duplication of nodes can be useful to emulate a crack in the model.</li>
24 <li>Unite meshes by \subpage sewing_meshes_page "sewing" free borders,
25 conform free borders, border to side or side elements.</li>
26 <li>\subpage merging_nodes_page "Merge Nodes", considered coincident
27 within the indicated tolerance.</li>
28 <li>\subpage merging_elements_page "Merge Elements", considered coincident
29 within the indicated tolerance.</li>
30 <li>\subpage mesh_through_point_page "Move Nodes" to an arbitrary location
31 with consequent transformation of all adjacent elements and edges.</li>
32 <li>\subpage diagonal_inversion_of_elements_page "Invert an edge" between neighboring triangles.</li>
33 <li>\subpage uniting_two_triangles_page "Unite two triangles".</li>
34 <li>\subpage uniting_set_of_triangles_page "Unite several adjacent triangles".</li>
35 <li>\subpage changing_orientation_of_elements_page "Change orientation"
36 of the selected elements.</li>
37 <li>\subpage reorient_faces_page "Reorient faces".</li>
38 <li>\subpage cutting_quadrangles_page "Cut a quadrangle" into two triangles.</li>
39 <li>\subpage split_to_tetra_page "Split" volumic elements into tetrahedra or prisms.</li>
40 <li>\subpage smoothing_page "Smooth" elements, reducung distortions in
41 them by adjusting the locations of element corners.</li>
42 <li>Create an \subpage extrusion_page "extrusion" along a vector.</li>
43 <li>Create an \subpage extrusion_along_path_page "extrusion along a path".</li>
44 <li>Create an edge or a surface by \subpage revolution_page "revolution"
45 of the selected node or edge.</li>
46 <li>Apply \subpage pattern_mapping_page "pattern mapping".</li>
47 <li>\subpage convert_to_from_quadratic_mesh_page "Convert regular mesh to quadratic",
49 <li>\subpage make_2dmesh_from_3d_page "Generate boundary elements".</li>
50 <li>\subpage generate_flat_elements_page "Generate flat elements on group boundaries or on faces".</li>
51 <li>\subpage cut_mesh_by_plane_page "Cut a tetrahedron mesh by a plane".</li>
54 It is possible to \ref edit_anchor "modify the mesh" of lower
55 dimension before generation of mesh of higher dimension.
59 \note It is possible to use the variables defined in the SALOME \b NoteBook
60 to specify the numerical parameters used for modification of any object.
