 \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:
+a set of entities with a simple topology. 
 
-<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>
-</ul>
+Meshes are stored in DAT, MED, UNV, STL, CGNS, GMF and SAUVE formats and can be

 entities including:
 
 <ul>
 <li>\b Node &mdash; 0D object of a mesh presented by a point with coordinates (x, y, z).</li>
+<li>\b 0D element &mdash; element of a mesh defined by one node.</li>
 <li>\b Edge &mdash; 1D element of a mesh defined by two nodes.</li>
 <li>\b Face &mdash; 2D element of a mesh defined by three or four edges (closed contour).</li>
 <li>\b Volume &mdash; 3D element of a mesh defined by several faces.</li>
+<li>\b Ball element &mdash; discrete element of a mesh defined by a node and a diameter.</li>
 </ul>
 
 &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;These entities are
 considered as topological entities and they don't
 imply any geometric representation. Only \b Nodes reference  geometric
 representations of points with definite coordinates. The node entity

 described in the following way:
