+Python package smesh defines several classes, destined for easy and
+clear mesh creation and edition.
-\n Please draw your attention to the below notes before address to
-the \ref smeshDC "documentation for smesh.py"
+Documentation for smesh package is available in two forms:
-\n 1. The main page of the \ref smeshDC "documentation for smesh.py"
- contains a list of data structures and a list of functions,
- provided by the package smesh.py. The first item in the data
- structures list (\ref smeshDC::smeshDC "class smesh") also
- represents documentation for methods of the package smesh.py itself.
+The <a href="smeshpy_doc/modules.html"> structured
+documentation for smesh package</a>, where all methods and
+classes are grouped by their functionality, like it is done in the GUI documentation
+and the \ref smeshDC "linear documentation for smesh package"
+grouped only by classes, declared in the smesh.py file.
-\n 2. Package smesh.py gives interface to create and manage
- meshes. Please, use it to create an empty mesh or to import
- it from data file.
+The main page of the \ref smeshDC "linear documentation for smesh package"
+contains a list of data structures and a list of
+functions, provided by the package smesh.py. The first item in
+the list of data structures (\ref smeshDC::smeshDC "class smesh")
+also represents documentation for the methods of the package smesh.py itself.
-\n 3. Once you have created a mesh, you can manage it via its own
- methods. See \ref smeshDC::Mesh "class Mesh" documentation for
- them (it is also accessible by the second item "class Mesh" in the
- data structures list).
+The package smesh.py provides an interface to create and handle
+meshes. Use it to create an empty mesh or to import it from the data file.
-\n 4. Class Mesh allows to assign algorithms to a mesh.
-\n \t Please note, that there are always available some algorithms,
- included in standard Salome installation:
- - REGULAR(1D), COMPOSITE(1D), MEFISTO(2D), Quadrangle(2D), Hexa(3D), etc.
+Once a mesh has been created, it is possible to manage it via its own
+methods, described at \ref smeshDC::Mesh "class Mesh" documentation
+(it is also accessible by the second item "class Mesh" in the list of data structures).
-\n Also there are some algorithms, which can be installed optionally,
-\n some of them are based on open-source meshers:
- - NETGEN(1D-2D,2D,1D-2D-3D,3D),
+Class \b Mesh allows assigning algorithms to a mesh.
+Please note, that some algorithms, included in the standard SALOME
+distribution are always available:
+- REGULAR (1D)
+- COMPOSITE (1D)
+- MEFISTO (2D)
+- Quadrangle (2D)
+- Hexa(3D)
+- etc...
-\n others are based on commercial meshers:
- - GHS3D(3D).
+There are also some algorithms, which can be installed optionally,
+some of them are based on open-source meshers:
+- NETGEN (1D-2D, 2D, 1D-2D-3D, 3D)
-\n \t To add hypotheses, please use interfaces, provided by the
- assigned algorithms.
+... and others are based on commercial meshers:
+- GHS3D (3D)
+- BLSURF (2D)
+
+To add hypotheses, use the interfaces, provided by the assigned
+algorithms.
+
+Below you can see an example of usage of the package smesh for 3d mesh generation.
