\n The MESH module contains a set of meshing algorithms, which are
-used for meshing entities (1D, 2D, 3D) composing geometrical objects.
+used for meshing entities (1D, 2D, 3D sub-shapes) composing
+geometrical objects.
+
+An algorithm represents either an implementation of a certain meshing
+technique or an interface to the whole meshing program generating elements
+of several dimensions.
- For meshing of 1D entities (edges):

-- Wire Discretisation meshing algorithm - splits a wire into a
-number of mesh segments following any 1D hypothesis.
-- Composite Side Discretisation algorithm - allows to apply any 1D
-hypothesis to a whole side of a geometrical face even if it is
-composed of several edges provided that they form C1 curve, have the
-same hypotheses assigned and form one side in all faces of the main
-shape of a mesh.

- For meshing of 2D entities (faces):
-- Triangle meshing algorithms (Mefisto and Netgen 1D-2D ) - Faces
-are split into triangular elements.
-- Quadrangle meshing algorithm (Mapping) - Faces are split into
-quadrangular elements.

+- \subpage cartesian_algo_page "Body Fitting" meshing
+ algorithm - solids are split into hexahedral elements forming
+ a Cartesian grid; polyhedra and other types of elements are generated
+ where the geometrical boundary intersects Cartesian cells.
