|
\n In MESH you can create groups of elements of different types. To
|
|
create a group of elements in the \b Mesh menu select <b>Create
|
|
Group</b>.
|
|
\n To create any group you should define the following:
|
|
<ul>
|
|
<li><b>Mesh</b> - the name of the mesh whose elements will form your
|
|
group. You can select your mesh in the Objet Browser or in the 3D
|
|
viewer.</li>
|
|
<li><b>Elements Type</b> - set of radio buttons allows to select the type of
|
|
elements which will form your group:</li>
|
|
<ul>
|
|
<li><b>Nodes</b></li>
|
|
<li><b>Edges</b></li>
|
|
<li><b>Faces</b></li>
|
|
<li><b>Volumes</b></li>
|
|
</ul>
|
|
<li><b>Name</b> field allows to enter the name of your new group.</li>
|
|
</ul>
|
|
SALOME Platform distinguishes between the two Group types:
|
|
<b>Standalone Group</b> and <b>Group on Geometry</b>.
|
|
|
|
<br><h2>Standalone Group</h2>
|
|
|
|
<b>Standalone Group</b> consists of mesh elements, which you can define in
|
|
two possible ways.
|
|
<ul>
|
|
<li>Choosing them manually with the mouse in the 3D Viewer. You can
|
|
click on an element in the 3D viewer and it will be highlighted. After
|
|
that click the \b Add button and the ID of this element will be added to
|
|
the list.</li>
|
|
<li>Applying Filters. The <b>Set filter</b> button allows to apply a
|
|
definite filter to selection of the elements of your group. See more
|
|
about filters on the
|
|
\ref selection_filter_library_page "Selection filter library" page.</li>
|
|
</ul>
|
|
To remove a selected element or elements from the list click the
|
|
\b Remove button. The <b>Sort List</b> button allows to sort the list of IDs of
|
|
mesh elements.
|
|
\n <b>Select from</b> set of fields allows to choose a submesh or an existing
|
|
group whose elements of the previously defined type will be added to
|
|
the list of elements which will form the new group.
|
|
\n <b>Color</b> - allows to assign to the group a certain color, for
|
|
example, defining boundary conditions. This feature introduces a
|
|
useful element of preprocessing in Mesh module. Note that <b>Color</b> attribute defines
|
|
the colors used for the display of the elements of the group.
|
|
\n <b>Warning</b> The Med Color group interface may change in future versions of Salome.

|
For example, to create a new group containing all entities of the
|
|
existing group and some other faces selected in the viewer:
|
|
<ul>
|
|
<li> select the "Face" type of entities and input the name of the new group.</li>
|
|
<li> checks "Group" checkbox in "Select From" group.</li>
|
|
<li> select the existing group in the object browser or in the viewer.</li>
|
|
<li> click "Add" in "Content" group. "Id Elements" list will be filled
|
|
with IDs of faces belonging to the exising group.</li>
|
|
<li> select other faces in the viewer.</li>
|
|
<li> click "Apply" button to create the new group.</li>
|
|
</ul>
|
|
|
|
Please note that the new group does not have references to the source
|
|
group. It contains only the list of face IDs. So if the old group will
|
|
be changed, the new one will not be modified.

|
<br><h2>Group on Geometry</h2>
|
|
|
|
To create a group on geometry check <b>Group on geometry</b> in the \b Group
|
|
\b type field. <b>Group on geometry</b> contains the elements of a certain type
|
|
belonging to the selected geometrical object. To define a group select
|
|
in the Objet Browser or in the 3D viewer a geometrical object from
|
|
which the elements will be taken. After confirmation of the operation
|
|
a new group of mesh elements will be created.
