\n \b MESH represents a discretization of a geometrical CAD model into
-a set of entities with a simple topology. In MESH there are two
-options of creation of meshes, you can:

-<ul>
-<li>generate meshes on the basis of geometrical shapes produced in the GEOM module,</li>
-<li>create your own meshes using the MESH functions destined for modification of generated meshes.</li>

+The \b topology of a mesh is described by the relationships between its
entities including:
<ul>
<li>\b Node — 0D object of a mesh presented by a point with coordinates (x, y, z).</li>
+<li>\b 0D element — element of a mesh defined by one node.</li>
<li>\b Edge — 1D element of a mesh defined by two nodes.</li>
<li>\b Face — 2D element of a mesh defined by three or four edges (closed contour).</li>
<li>\b Volume — 3D element of a mesh defined by several faces.</li>
