|
|
|
|
\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 your group.
|
|
\n <b>Color Number</b> (integer only, ranging from 0 to 9999) - allows to
|
|
assign to the group a certain index, for example, defining boundary
|
|
conditions. This feature introduces a useful element of preprocessing
|
|
in Mesh module. Note that <b>Color number</b> attribute has nothing to do
|
|
with the colors used for the display of the elements of the group.

|
|
|
<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.
