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

*Adding nodes and elements*mesh elements from nodes to polyhedrons at an arbitrary place in the mesh.*Adding Quadratic Elements*mesh elements from quadratic segments to quadratic hexahedrons at an arbitrary place in the mesh.*Removing nodes and elements*any existin” mesh elements and nodes.*Translation*in the indicated direction the mesh or some of its elements.*Rotation*by the indicated axis and angle the mesh or some of its elements.*Scale*the mesh or some of its elements.*Symmetry*the mesh through a point, a vector or a plane of symmetry.*Duplicate Nodes or/and Elements*. Duplication of nodes can be useful to emulate a crack in the model.- Unite meshes by
*Sewing meshes*free borders, border to side or side elements. *Merging nodes*, coincident within the indicated tolerance.*Merging Elements*based on the same nodes.*Moving nodes*to an arbitrary location with consequent transformation of all adjacent elements.*Diagonal inversion of two triangles*between neighboring triangles.*Uniting two triangles*.*Uniting a set of triangles*.*Changing orientation of elements*of the selected elements.*Orient faces*by several means.*Cutting quadrangles*into two triangles.*Splitting volumes*volumic elements into tetrahedra or prisms.*Split bi-quadratic into linear*elements into linear ones without creation of additional nodes.*Smoothing*elements, reducung distortions in them by adjusting the locations of nodes.- Create an
*Extrusion*along a vector or by normal to a discretized surface. - Create an
*Extrusion along Path*. - Create elements by
*Revolution*of the selected nodes and elements. - Apply
*Pattern mapping*. *Convert to/from Quadratic Mesh*, or vice versa.*Generate boundary elements*.*Generate flat elements on group boundaries or on faces*.*Cut a tetrahedron mesh by a plane*.

Note

It is possible to *Editing the mesh* 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.
