5 In the Mesh module you can set mesh preferences, which can be used in
6 later sessions with this module.
8 <h2>General Preferences</h2>
10 \image html pref21.png
12 - <b>Automatic Update</b>
13 - If you toggle <b>Automatic Update</b> checkbox, the model in your
14 viewer automatically updated when you make changes in it, depending on
15 values of additional preferences specified below.
16 - <b>Size limit (elements)</b> - allows to specify the maximum
17 number of elements in the resulting mesh for which the automatic updating
18 of the presentation is performed. This option affects only
19 <b>Compute</b> operation. Zero value means "no limit". Default value
20 is 500 000 mesh elements.
21 - <b>Incremental limit check</b> - when this control is switched on,
22 check for mesh size limit will be applied not to total number of
23 elements in resulting mesh, but iteratively to each entity types
24 in the following order: 0D elements, edges, faces, volumes, balls;
25 at each step number of entities of given type will be added to the
26 total number of elements computed at previous step - if resulting
27 number of elements does not exceed size limit, the entities of
28 this type will be shown, otherwise user will be warned that some
29 entities are not shown.
31 - <b>Quality Controls</b>
32 - If you toggle <b>Display entity</b>, both faces and edges of an
33 object will be displayed in the viewer by default.
34 - If you toggle <b>Use precision</b> checkbox, you can display numbers in
35 <b>Quality Control</b> diagrams at the necessary level of precision.
36 - <b>Number of digits after point</b> - defines precision for
37 <b>Quality Controls</b>. By default, numbers in <b>Quality Control</b>
38 diagrams are presented as integers.
39 - <b>Double nodes tolerance</b> defines the maximal distance between two
40 mesh nodes, at which they are considered coincident by <b>Double nodes</b>
43 - <b>Display mode</b> - allows to set Wireframe, Shading, Nodes or Shrink
44 presentation mode as default.
46 - <b>Representation of the 2D quadratic elements</b>
47 - <b>Representation of the 2D quadratic elements</b> combobox - allows
48 to select lines or arcs for representation of quadratic elements.
49 - <b>Maximum Angle</b> - maximum deviation angle used by the
50 application to build arcs.
53 - If you toggle <b>Automatically create groups for MED export</b> checkbox,
54 this operation will be carried out automatically.
56 - <b>Mesh computation</b>
57 - <b>Show a computation result notification</b> combobox allows to
58 select the notification mode about a mesh computation result.
59 There are 3 possible modes:
60 - <b>Never</b> - do not show the result dialog at all;
61 - <b>Errors only</b> - the result dialog will be shown if there were
62 some errors during a mesh computation;
63 - <b>Always</b> - show the result dialog after each mesh
64 computation. This is a default mode.
66 - <b>Mesh information</b>
67 - <b>Mesh element information</b> - change the way mesh element
69 - <b>Simple</b> - as a plain text
70 - <b>Tree</b> - in a tree-like form
71 - <b>Automatic nodes compute limit</b> - allows to define the size limit for the
72 mesh groups for which the number of underlying nodes is calculated
73 automatically. If the group size exceeds the value set in the preferences,
74 the user will have to press \em Compute button explicitly. Zero value
75 means "no limit". By default the value is set to 100 000 mesh elements.
76 - <b>Automatic controls compute limit</b> - allows to define the size limit for the
77 mesh elements for which the Aspect Ratio histogram is calculated
78 automatically. If the mesh elements size exceeds the value set in the preferences,
79 the user will have to press \em Compute button explicitly. Zero value
80 means "no limit". By default the value is set to 3 000 mesh elements.
81 - <b>Show details on groups in element information tab</b> - when
82 this option is switched off (default), only the names of groups, to which the node
83 or element belongs, are shown in the \ref mesh_element_info_anchor "Info Tab"
84 tab of "Mesh Information" dialog box. If this option is
85 switched on, the detailed information on groups is shown.
86 - <b>Dump base information</b> - allows to dump base mesh information to the
87 file, see \ref mesh_infos_page.
88 - <b>Dump element information</b> - allows to dump element information to the
89 file, see \ref mesh_infos_page.
90 - <b>Dump additional information</b> - allows to dump additional mesh
91 information to the file, see \ref mesh_infos_page.
92 - <b>Dump controls information</b> - allows to dump quality mesh
93 information to the file, see \ref mesh_infos_page.
95 - <b>Automatic Parameters</b>
96 - <b>Ratio Bounding Box Diagonal / Max Size</b> - this parameter is
97 used for automatic meshing: ratio between the bounding box of the
98 meshed object and the Max Size of segments.
99 - <b>Default Number of Segments</b> - allows defining the default
100 number of segments on each edge.
102 - <b>Mesh loading</b>
103 - If <b>No mesh loading from study file at hypothesis modification</b>
104 checkbox is on, the mesh data will not be loaded from the study file
105 when a hypothesis is modified. This allows saving time by omitting
106 loading data of a large mesh that is planned to be recomputed with other parameters.
108 - <b>Input fields precision</b>
109 - <b>Length precision</b> - allows to adjust input precision of coordinates and dimensions.
110 - <b>Angular precision</b> - allows to adjust input precision of angles.
111 - <b>Length tolerance precision</b> - allows to adjust input precision of tolerance of coordinates and dimensions.
112 - <b>Parametric precision</b> - allows to adjust input precision of parametric values.
113 - <b>Area precision</b> - allows to adjust input precision of mesh element area.
114 - <b>Volume precision</b> - allows to adjust input precision of mesh element volume.
117 - <b>Sub-shapes preview chunk size</b> - allows to limit the number
118 of previewed sub-shapes shown in the hypotheses creation dialog boxes,
119 for example "Reverse Edges" parameter of \ref number_of_segments_anchor "Number of segments" hypothesis.
122 - <b>Historical python dump</b> checkbox allows switching between
123 \a Historical and \a Snapshot dump mode:
124 - In \a Historical mode, Python Dump script includes all commands
125 performed by SMESH engine.
126 - In \a Snapshot mode, the commands relating to objects removed
127 from the Study as well as the commands not influencing the
128 current state of meshes are excluded from the script.
