+<li><b>Total thickness</b> - gives the total thickness of element layers.</li>
+<li><b>Number of layers</b> - defines the number of element layers.</li>
+<li><b>Stretch factor</b> - defines the growth factor of element height

+<li><b>Specified Faces/Edges are</b> - defines how the shapes specified by
+  the next parameter are used.
+<li><b> Faces/Edges with/without layers</b> - 
+  defines geometrical faces or edges on which element layers
+  either should be or should not be constructed, depending on the
+  value of the previous parameter (<b>Specified Faces/Edges are</b>). 
+  Faces (or edges) can be selected either in the Object Browser or in
+  the VTK Viewer.
+  \note A mesh shown in the 3D Viewer can prevent selection of faces
+  and edges, just hide the mesh to avoid this. To avoid a long wait when a
+  geometry with many faces (or edges) is displayed, the number of faces
+  (edges) shown at a time is limited by the value of "Sub-shapes
+  preview chunk size" preference (in Preferences/Mesh/General tab).<br>
+
+  If faces/edges without layers are specified, the element layers are
+  not constructed on geometrical faces shared by several solids in 3D
+  case and edges shared by several faces in 2D case. In other words,
+  in this mode the element layers can be constructed on boundary faces
+  and edges only, and are not constructed on internal faces and
+  edges. There is an exception to this rule: if a hypothesis is
+  assigned to a sub-mesh, the element layers can be constructed on
+  boundary faces/edges of the shape of this sub-mesh, at same time
+  possibly being internal faces/edges within the whole model.
