+A SALOME study can contain multiple meshes, but they do not
+implicitly compose one super-mesh, and finally each of them
+can be used (e.g. exported) only individually.
Mesh module provides several ways to create the mesh:
<ul>
<li>The main way is to \subpage constructing_meshes_page "construct the mesh"
on the basis of the geometrical shape produced in the Geometry
module. This way implies selection of
- - a geometrical object (<em> main shape</em>) and
+ - a geometrical object (<em>main shape</em>) and
- <em>meshing parameters</em> (\ref
basic_meshing_algos_page "meshing algorithms" and
characteristics (e.g. element size) of a
Construction of \subpage constructing_submeshes_page "sub-meshes"
allows to discretize some sub-shapes of the main shape, for example a face,
- using the meshing parameters that differ from those for other sub-shapes.<br>
+ using the meshing parameters that differ from those used for other sub-shapes.<br>
Meshing parameters of meshes and sub-meshes can be

generated using changed meshing parameters are removed and will be
(and exported to) the file in MED, UNV, STL, CGNS, DAT, GMF and
SAUVE formats.

+ <li>The 3D mesh can be generated from the 2D mesh, which was \ref
importing_exporting_meshes_page "imported" or manually created. To
setup the meshing parameters of a mesh not based on a geometry, just
invoke \ref editing_meshes_page "Edit mesh / sub-mesh" command on
(quadratic triangle, quadrangle, polygon, tetrahedron, hexahedron,
pentahedron and pyramid) and with central nodes (bi-quadratic triangle
and quadrangle and tri-quadratic hexahedron).<br>
-Quadratic mesh can be obtained in two ways:
+Quadratic mesh can be obtained in three ways:
- Using a global \ref quadratic_mesh_anchor "Quadratic Mesh"
hypothesis. (Elements with the central node are not generated in this way).
- Using \ref convert_to_from_quadratic_mesh_page operation.
-
+- Using an appropriate option of some meshing algorithms, which
+generate elements of several dimensions starting from mesh segments.
