In the Mesh module you can set mesh preferences, which can be used right now
|
|
or in later sessions with this module according to the preferences.
|
|
|
|
<h2>General Preferences</h2>
|
|
|
|
\image html pref21.png
|
|
|
|
\anchor automatic_update_pref
|
|
- <b>Automatic Update</b>
|
|
- <b>Automatic Update</b> - if activated, the mesh in your
|
|
viewer will be automatically updated after it's computation, depending on
|
|
values of additional preferences specified below.
|
|
- <b>Size limit (elements)</b> - allows specifying the maximum
|
|
number of elements in the resulting mesh for which the automatic updating
|
|
of the presentation is performed. This option affects only
|
|
\ref compute_anchor "Compute" operation. Zero value means "no
|
|
limit". Default value is 500 000 mesh elements.
|
|
- <b>Incremental limit check</b> - if activated,
|
|
the mesh size limit check is not applied to the total number of
|
|
elements in the resulting mesh, it is applied iteratively to each entity type
|
|
in the following order: 0D elements, edges, faces, volumes, balls.
|
|
At each step the number of entities of a certain type is added to the
|
|
total number of elements computed at the previous step - if the resulting
|
|
number of elements does not exceed the size limit, the entities of
|
|
this type are shown, otherwise the user is warned that some entities are not shown.
|
|
|
|
\anchor display_mode_pref

|
|
- <b>Quality Controls</b>
|
|
- <b>Display entity</b> - if activated, only currently
|
|
\ref quality_page "controlled" entities are displayed in the
|
|
viewer and other entities are temporarily hidden. For example if you
|
|
activate \ref length_page "Length" quality control, which controls
|
|
the length of mesh segments, then only mesh segments are
|
|
displayed and faces and volumes are hidden.
|
|
- <b>Use precision</b> - if activated, all quality controls
|
|
will be computed at precision defined by <b>Number of digits after
|
|
point</b> - as integers by default.
|
|
\anchor dbl_nodes_tol_pref
|
|
- <b>Double nodes tolerance</b> - defines the maximal distance between two
|
|
mesh nodes, at which they are considered coincident by
|
|
\ref double_nodes_control_page "Double nodes" quality control.

|
the number of underlying nodes is calculated
|
|
automatically. If the group size exceeds the value set in the preferences,
|
|
the user will have to press \em Compute button explicitly. Zero value
|
|
means "no limit". By default the value is set to 100 000 mesh elements.
|
|
\anchor auto_control_limit_pref
|
|
- <b>Automatic controls compute limit</b> - allows defining a
|
|
maximal number of mesh elements for which the quality controls
|
|
in the \ref mesh_quality_info_anchor "Quality Information"
|
|
tab page are calculated automatically. If the number of mesh elements
|
|
exceeds the value set in the preferences, it is necessary to press
|
|
\b Compute button explicitly to calculate a quality measure. Zero value
|
|
means "no limit". By default the value is set to 3 000 mesh
|
|
elements.
|

this option is switched off (default), only the names of groups, to which the node
|
|
or element belongs, are shown in the \ref mesh_element_info_anchor "Element Info"

|
|
switched on, the detailed information on groups is shown.

|
|
|
|

|
|
- <b>Ratio Bounding Box Diagonal / Max Size</b> - defines the ratio
|
|
between the bounding box of the meshed object and the Max Size of
|
|

|
|
- <b>No mesh loading from study file at hypothesis modification</b> - if
|
|
activated, the mesh data will not be loaded from the study file
|
|

|
|
loading data of a large mesh that is planned to be recomputed with other parameters.
|
|
|
|
- <b>Input fields precision</b> - allows to adjust input precision of
|
|
different parameters. The semantics of the precision values is
|
|
described in detail in <em>Using input widgets</em> chapter of GUI
|
|
documentation (Introduction to Salome Platform / Introduction to GUI /
|
|
Using input widgets). In brief: \b positive precision value is the
|
|
maximum allowed number of digits after the decimal point in the
|
|
fixed-point format; \b nagative precision value is the maximum
|
|
allowed number of significant digits in mantissa in either the
|
|
fixed-point or scientific format.
|
|

|
|

|
|
for example "Reverse Edges" parameter of
|
|
\ref number_of_segments_anchor "Number of segments" hypothesis.
|
|
|
|
- <b>Python Dump</b>
|
|
- <b>Historical python dump</b> - allows switching between
|
|
\a Historical and \a Snapshot dump mode:
|
|
- In \a Historical mode, Python Dump script includes all commands
|
|
performed by SMESH engine.
|
|
- In \a Snapshot mode, the commands relating to objects removed
|
|
from the Study as well as the commands not influencing the
|
|
current state of meshes are excluded from the script.
