Salome provides a vast specter of mesh modification and transformation operations, giving the possibility to:
|
|
|
|
* :ref:`Add <adding_nodes_and_elements_page>` mesh elements from nodes to polyhedrons at an arbitrary place in the mesh.
|
|
* :ref:`Add quadratic <adding_quadratic_elements_page>` mesh elements from quadratic segments to quadratic hexahedrons at an arbitrary place in the mesh.
|
|
* :ref:`Remove <removing_nodes_and_elements_page>` any existing mesh elements and nodes.
|
|
* :ref:`Convert linear mesh to quadratic <convert_to_from_quadratic_mesh_page>`, or vice versa.
|
|
* :ref:`Generate boundary elements <make_2dmesh_from_3d_page>`.
|
|
* :ref:`Translate <translation_page>` in the indicated direction the mesh or some of its elements.
|
|
* :ref:`Rotate <rotation_page>` by the indicated axis and angle the mesh or some of its elements.
|
|
* :ref:`Scale <scale_page>` the mesh or some of its elements.
|
|
* :ref:`Mirror <symmetry_page>` the mesh through a point, a vector or a plane of symmetry.
|
|
* :ref:`double_nodes_page`. Duplication of nodes can be useful to emulate a crack in the model.
|
|
* :ref:`Merge Nodes<merging_nodes_page>` coincident within the indicated tolerance.
|
|
* :ref:`Merge Elements <merging_elements_page>` based on the same nodes.
|
|
* Create an :ref:`extrusion <extrusion_page>` along a vector or by normal to a discretized surface.
|
|
* Create an :ref:`extrusion along a path <extrusion_along_path_page>`.
|
|
* Create elements by :ref:`revolution <revolution_page>` of the selected nodes and elements.
|
|
* :ref:`Move Nodes <mesh_through_point_page>` to an arbitrary location with consequent transformation of all adjacent elements.
|
|
* :ref:`Change orientation <changing_orientation_of_elements_page>` of the selected elements.
|
|
* :ref:`Orient faces <reorient_faces_page>` by several means.
|
|
* Unite meshes by :ref:`sewing <sewing_meshes_page>` free borders, border to side or side elements.
|
|
* :ref:`Invert an edge <diagonal_inversion_of_elements_page>` between neighboring triangles.
|
|
* :ref:`Unite two triangles <uniting_two_triangles_page>`.
|
|
* :ref:`Unite several adjacent triangles <uniting_set_of_triangles_page>`.
|
|
* :ref:`Cut a quadrangle <cutting_quadrangles_page>` into two triangles.
|
|
* :ref:`Split <split_to_tetra_page>` volumic elements into tetrahedra or prisms.
|
|
* :ref:`Split bi-quadratic <split_biquad_to_linear_page>` elements into linear ones without creation of additional nodes.
|
|
* :ref:`Smooth <smoothing_page>` elements, reducung distortions in them by adjusting the locations of nodes.
|
|
* Apply :ref:`pattern mapping <pattern_mapping_page>`.
|
|
* :ref:`generate_flat_elements_page`.
|
|
* :ref:`cut_mesh_by_plane_page`.

.. note::
|
|
You can use these operations to :ref:`modify the mesh <edit_anchor>` of a lower dimension before generation of the mesh of a higher dimension.
|
|
|
|
.. note::
|
|
It is possible to use the variables defined in the SALOME **NoteBook** to specify the numerical parameters used for modification of any object.
