-There are 0D, 1D, 2D and 3D quality controls.
+There are four types of quality controls, corresponding to node, edge,
+face and volume entity type.
-0D mesh quality controls:
+Node quality controls:
<ul>
-<li>\ref free_nodes_page "Free nodes"</li>
+<li>\subpage free_nodes_page "Free nodes"</li>
+<li>\subpage double_nodes_control_page "Double nodes"</li>
</ul>
-1D mesh quality controls:
+Edge quality controls:
<ul>
+<li>\subpage free_edges_page "Free edges"</li>
<li>\subpage free_borders_page "Free borders"</li>
-<li>\subpage borders_at_multi_connection_page "Borders at multi-connection"</li>
<li>\subpage length_page "Length"</li>
+<li>\subpage borders_at_multi_connection_page "Borders at multi-connection"</li>
+<li>\subpage double_elements_page "Double edges"</li>
</ul>
-2D mesh quality controls:
+Face quality controls:
<ul>
-<li>\subpage free_edges_page "Free edges"</li>
+<li>\subpage free_faces_page "Free faces"</li>
+<li>\subpage bare_border_faces_page "Bare border faces"</li>

<li>\subpage length_2d_page "Length 2D"</li>
<li>\subpage borders_at_multi_connection_2d_page "Borders at multi-connection 2D"</li>
<li>\subpage area_page "Area"</li>
<li>\subpage minimum_angle_page "Minimum angle"</li>
<li>\subpage warping_page "Warping"</li>
<li>\subpage skew_page "Skew"</li>
+<li>\subpage max_element_length_2d_page "Element Diameter 2D"</li>
+<li>\ref double_elements_page "Double faces"</li>
</ul>
-3D mesh quality controls:
+Volume quality controls:
<ul>
<li>\subpage aspect_ratio_3d_page "Aspect ratio 3D"</li>
<li>\subpage volume_page "Volume"</li>
-<li>\subpage free_faces_page "Free faces"</li>
+<li>\subpage max_element_length_3d_page "Element Diameter 3D"</li>
+<li>\subpage bare_border_volumes_page "Bare border volumes"</li>
+<li>\subpage over_constrained_volumes_page "Over-constrained volumes"</li>
+<li>\ref double_elements_page "Double volumes"</li>
</ul>
+To manage the quality controls call pop-up in the VTK viewer and select "Controls" sub-menu
