3 \page mesh_infos_page Mesh Information
5 The user can obtain information about the selected mesh object
6 (mesh, sub-mesh or group) using <b>Mesh Information</b> dialog box.
8 To view the <b>Mesh Information</b>, select your mesh, sub-mesh or
9 group in the <b>Object Browser</b> and invoke <b>Mesh Information</b>
10 item from the \b Mesh menu or click <em>"Mesh Information"</em> button
13 <center>\image html image49.png
14 <em>"Mesh Information" button</em></center>
16 The <b>Mesh Information</b> dialog box provides three tab pages:
17 - <b>\ref advanced_mesh_infos_anchor "Base Info"</b> - to show base
18 information about the selected mesh object.
19 - <b>\ref mesh_element_info_anchor "Element Info"</b> - to show
20 detailed information about the selected mesh node or element.
21 - <b>\ref mesh_addition_info_anchor "Additional Info"</b> - to show additional information available
22 for the selected mesh, sub-mesh or group object.
23 - <b>\ref mesh_quality_info_anchor "Quality Info"</b> - to show
24 overall quality information about the selected mesh, sub-mesh or group object.
26 \anchor advanced_mesh_infos_anchor
27 <h2>Base Information</h2>
29 The <b>Base Info</b> tab page of the dialog box provides general
30 information on the selected object - mesh, sub-mesh or mesh group:
31 name, type, total number of nodes and elements separately for each
32 type: 0D elements, edges, faces, volumes, balls.

37 \anchor mesh_element_info_anchor
38 <h2>Mesh Element Information</h2>
40 The <b>Element Info</b> tab page of the dialog box gives detailed
41 information about the selected mesh node(s) or element(s), namely:
45 - Coordinates (X, Y, Z);
46 - Connectivity information (connected elements);
47 - Position on a shape (for meshes built on a geometry);
48 - Groups information (names of groups the node belongs to).

51 <em>"Element Info" page, node information</em></center>
56 - Type (triangle, quadrangle, etc.);
57 - Gravity center (X, Y, Z coordinates);
58 - Connectivity information (connected nodes);
59 - Quality controls (area, aspect ration, volume, etc.);
60 - Position on a shape (for meshes built on a geometry);
61 - Groups information (names of groups the element belongs to).

66 The use can either input the ID of a node or element he wants to
67 analyze directly in the dialog box or select the node(s) or element(s) in
70 \note The information about the groups, to which the node or element belongs,
71 can be shown in a short or in a detailed form. By default, for performance
72 reasons, this information is shown in a short form (group names
73 only). The detailed information on groups can be switched on via the user
74 preferences, see \ref mesh_preferences_page.
76 \anchor mesh_addition_info_anchor
77 <h2>Additional Information</h2>
79 The <b>Additional Info</b> tab page of the dialog box provides an
80 additional information on the selected object: mesh, sub-mesh or
83 For a mesh object, the following information is shown:
85 - Type: based on geomerty, imported, standalone
86 - Shape (if mesh is based on geometry)
87 - File (if mesh is imported from the file)

92 <em>"Additional Info" page, mesh information</em></center>
95 For a sub-mesh object, the following information is shown:
100 <center>\image html addinfo_submesh.png
101 <em>"Additional Info" page, sub-mesh information</em></center>
104 For a group object, the following information is shown:
107 - Type: standalone, group on geometry, group on filter
108 - Entity type: node, edge, face, volume
111 - Number of underlying nodes (for non-nodal groups)
113 <center>\image html addinfo_group.png
114 <em>"Additional Info" page, group information</em></center>
117 \note For the performance reasons, the number of underlying nodes is
118 computed only by demand. For this, the user should press the "Compute"
119 button (see picture). Also, the number of underlying nodes is
120 automatically calculated if the size of the group does not exceed
121 the "Automatic nodes compute limit" set via the "Mesh information"
122 preferences (zero value means no limit).
124 \anchor mesh_quality_info_anchor
125 <h2>Quality Information</h2>
127 The <b>Quality Info</b> tab page of the dialog box provides overal
128 mesh quality controls information on the selected object - mesh,
129 sub-mesh or mesh group:
132 - Number of the free nodes;
133 - Number of double nodes;
135 - Number of double edges;
137 - Number of double faces;
138 - Number of over-constrained faces;
139 - Aspect Ratio histogram;
140 - Volume information:
141 - Number of double volumes;
142 - Number of over-constrained volumes;
143 - Aspect Ratio 3D histogram.

148 \note User can set "Double nodes tolerance" in the dialog for local change
149 or via the "Quality controls" in Mesh preferences.
151 \note For the perfomance reason, all quality control values for the big meshes are
152 computed only by demand. For this, the user should press the "compute"
153 button (see picture). Also, values are automatically computed if the number of the
154 nodes / elements does not exceed the "Automatic controls compute limit" set
155 via the "Mesh information" preferences (zero value means no limit).
157 The button \b "Dump" allows printing the information displayed in the
158 dialog box to a .txt file.
160 In case you get <b>Mesh Information</b> via a TUI script, the information is
161 displayed in the Python Console.
162 <b>See the</b> \ref tui_viewing_mesh_infos "TUI Example".
