\page about_meshes_page About meshes
\n \b MESH represents a discrete approximation of a subset of the
three-dimensional space by \ref mesh_entities "elementary geometrical elements".
three-dimensional space by \ref mesh_entities "elementary geometrical
elements".
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:
