The <b>Mesh Information</b> dialog box provides three tab pages:
- <b>\ref advanced_mesh_infos_anchor "Base Info"</b> - to show base
-information about the selected mesh object
+information about the selected mesh object.
- <b>\ref mesh_element_info_anchor "Element Info"</b> - to show
detailed information about the selected mesh node or element.
- <b>\ref mesh_addition_info_anchor "Additional Info"</b> - to show additional information available
for the selected mesh, sub-mesh or group object.
+- <b>\ref mesh_quality_info_anchor "Quality Info"</b> - to show
+overall quality information about the selected mesh, sub-mesh or group object.
\anchor advanced_mesh_infos_anchor
<h2>Base Information</h2>
The <b>Base Info</b> tab page of the dialog box provides general
information on the selected object - mesh, sub-mesh or mesh group:
name, type, total number of nodes and elements separately for each
-type: 0D elements, edges, faces and volumes.
+type: 0D elements, edges, faces, volumes, balls.

\anchor mesh_element_info_anchor
<h2>Mesh Element Information</h2>
-The <b>Element Info</b> tab page of the dialog box gives basic
-information about the type, coordinates and connectivity of the
-selected mesh node or element.
+The <b>Element Info</b> tab page of the dialog box gives detailed
+information about the selected mesh node(s) or element(s), namely:
-\image html eleminfo1.png
-<center><em>"Element Info" page, node information</em></center>
+- For a node:
+ - Node ID;
+ - Coordinates (X, Y, Z);
+ - Connectivity information (connected elements);
+ - Position on a shape (for meshes built on a geometry);
+ - Groups information (names of groups the node belongs to).

+- For an element:
+ - Element ID;
+ - Type (triangle, quadrangle, etc.);
+ - Gravity center (X, Y, Z coordinates);
+ - Connectivity information (connected nodes);
+ - Quality controls (area, aspect ration, volume, etc.);
+ - Position on a shape (for meshes built on a geometry);
+ - Groups information (names of groups the element belongs to).

The use can either input the ID of a node or element he wants to
-analyze directly in the dialog box or select the node or element in
+analyze directly in the dialog box or select the node(s) or element(s) in
the 3D viewer.
+\note The information about the groups, to which the node or element belongs,
+ can be shown in a short or in a detailed form. By default, for performance
+reasons, this information is shown in a short form (group names
+only). The detailed information on groups can be switched on via the user
+preferences, see \ref mesh_preferences_page.

\anchor mesh_addition_info_anchor
<h2>Additional Information</h2>
- Groups
- Sub-meshes

For a sub-mesh object, the following information is shown:
- Parent mesh
- Shape

+<center>\image html addinfo_submesh.png

For a group object, the following information is shown:
- Color
- Number of underlying nodes (for non-nodal groups)

\note For the performance reasons, the number of underlying nodes is
the "Automatic nodes compute limit" set via the "Mesh information"
preferences (zero value means no limit).
+\anchor mesh_quality_info_anchor
+<h2>Quality Information</h2>
+
+The <b>Quality Info</b> tab page of the dialog box provides overal
+mesh quality controls information on the selected object - mesh,
+sub-mesh or mesh group:
+- Name;
+- Nodes information:
+ - Number of the free nodes;
+ - Number of double nodes;
+- Edges information:
+ - Number of double edges;
+- Faces information:
+ - Number of double faces;
+ - Number of over-constrained faces;
+ - Aspect Ratio histogram;
+- Volume information:
+ - Number of double volumes;
+ - Number of over-constrained volumes;
+ - Aspect Ratio 3D histogram.
+
+<center>\image html ctrlinfo.png
+<em>"Quality Info" page</em></center>
+
+\note For the perfomance reason, the Aspect Ratio histogram for the big meshes is
+computed only by demand. For this, the user should press the "Compute"
+button (see picture). Also, histogram is automatically computed if the size of the
+elements does not exceed the "Automatic controls compute limit" set
+via the "Mesh information" preferences (zero value means no limit).
+
+The button \b "Dump" allows printing the information displayed in the
+dialog box to a .txt file.
+
In case you get <b>Mesh Information</b> via a TUI script, the information is
displayed in the Python Console.
<b>See the</b> \ref tui_viewing_mesh_infos "TUI Example".
