<em>To split volumes:</em>
<ol>
-<li>Display a mesh, a sub-mesh or a group in the 3D viewer.</li>
+<li>Select a mesh, a sub-mesh or a group.</li>
<li>In the \b Modification menu select the <b>Split Volumes</b> item or
click <em>"Split Volumes"</em> button in the toolbar.
<li>If \b Tetrahedron element type is selected, <b> Split hexahedron </b> group allows specifying the number of tetrahedra a hexahedron will be split into. If the chosen method does not allow to get a conform mesh, a generic solution is applied: an additional node is created at the gravity center of a hexahedron, serving an apex of tetrahedra, all quadrangle sides of the hexahedron are split into two triangles each serving a base of a new tetrahedron.</li>
-<li>If \Prism element type is selected, the <b>Split hexahedron</b> group looks as follows:
