 The \b topology of a mesh is described by the relationships between its
 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:
