\page mesh_infos_page Mesh Information
|
|
|
|
The user can obtain information about the selected mesh object
|
|
(mesh, sub-mesh or group) using <b>Mesh Information</b> dialog box.
|
|
|
|
To view the <b>Mesh Information</b>, select your mesh, sub-mesh or
|
|
group in the <b>Object Browser</b> and invoke <b>Mesh Information</b>
|
|
item from the \b Mesh menu or click <em>"Mesh Information"</em> button
|
|
in the toolbar.
|
|
|
|
<center>\image html image49.png
|
|
<em>"Mesh Information" button</em></center>
|
|
|
|
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.
|
|
- <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, volumes, balls.
|

\anchor mesh_element_info_anchor
|
|
<h2>Mesh Element Information</h2>
|
|
|
|
The <b>Element Info</b> tab page of the dialog box gives detailed
|
|
information about the selected mesh node(s) or element(s), namely:
|
|
|
|
- For a node:
|
|
- Node ID;
|
|
- Coordinates (X, Y, Z);
|
|
- Connectivity information (connected elements); double click in
|
|
this line makes the dialog show information of these elements;
|
|
- Position on a shape (for meshes built on a geometry);
|
|
- Groups information (names of groups the node belongs to).
|
|
|
|
<center>\image html eleminfo1.png
|
|
<em>"Element Info" page, node information</em></center>
|
|
<br>
|
|
|
|
- For an element:
|
|
- Element ID;
|
|
- Type (triangle, quadrangle, etc.);
|
|
- Gravity center (X, Y, Z coordinates);
|
|
- Connectivity information (connected nodes); double click in
|
|
a line of a node makes the dialog show information of this node;
|
|
- 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).
|
|
|
|

|
|
<em>"Element Info" page, element information</em></center>
|
|
|
|
The user can either input the ID of a node or element he wants to
|
|
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>
|
|
|
|
The <b>Additional Info</b> tab page of the dialog box provides an
|
|
additional information on the selected object: mesh, sub-mesh or
|
|
group.
|
|
|
|
For a mesh object, the following information is shown:
|
|
- Name
|
|
- Type: based on geomerty, imported, standalone
|
|
- Shape (if mesh is based on geometry)
|
|
- File (if mesh is imported from the file)
|
|
- Groups
|
|
- Sub-meshes
|

<em>"Additional Info" page, mesh information</em></center>
|
|
<br>
|
|
|
|
For a sub-mesh object, the following information is shown:
|
|
- Name
|
|
- Parent mesh
|
|
- Shape
|
|
|
|
<center>\image html addinfo_submesh.png
|
|
<em>"Additional Info" page, sub-mesh information</em></center>
|
|
<br>
|
|
|
|
For a group object, the following information is shown:
|
|
- Name
|
|
- Parent mesh
|
|
- Type: standalone, group on geometry, group on filter
|
|
- Entity type: node, edge, face, volume
|
|
- Size
|
|
- Color
|
|
- Number of underlying nodes (for non-nodal groups)
|
|
|
|

|
<em>"Additional Info" page, group information</em></center>
|
|
<br>
|
|
|
|
\note For the performance reasons, the number of underlying nodes is
|
|
computed only by demand. For this, the user should press the "Compute"
|
|
button (see picture). Also, the number of underlying nodes is
|
|
automatically calculated if the size of the group does not exceed
|
|
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 provides overall information about mesh quality controls on the selected object - mesh, sub-mesh or mesh group:
|
|
- Name;
|
|
- Nodes information:
|
|
- Number of 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.

<em>"Quality Info" page</em></center>
|
|
|
|
\note It is possible to set "Double nodes tolerance" in the dialog for a local change
|
|
or via the "Quality controls" in Mesh preferences.
|
|
|
|
\note For performance reasons, all quality control values for big meshes are
|
|
computed only by demand. For this, press the "compute"
|
|
button. Also, values are automatically computed if the number of
|
|
nodes / elements does not exceed the "Automatic controls compute limit" set
|
|
via the "Mesh information" preferences (zero value means that there is no limit).
|
|
|
|
\note The plot functionality is available only if GUI module is builded with Plot 2D Viewer (set option SALOME_USE_PLOT2DVIEWER to ON when building GUI module).
|
|
|
|
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.
|
|
|
|
See the \ref tui_viewing_mesh_infos "TUI Example".
