|
|
Sub-mesh is a mesh on a geometrical sub-object created with algorithms
|
|
and/or hypotheses other than the algorithms and hypotheses assigned to
|
|
the parent mesh on the parent object.
|
|
<br><br>
|
|
If a geometrical sub-object belongs to several geometrical objects
|
|
having different meshes or sub-meshes, it will be meshed with the
|
|
hypotheses of a sub-mesh of a lower dimension.<br>
|
|
For example, a face of a box is meshed with a sub-mesh using algorithms
|
|
and hypotheses other than the parent mesh on the whole box. The face
|
|
and the box share four edges, which will be meshed with algorithms and
|
|
hypotheses of the sub-mesh on the face, because the face is a 2D object
|
|
while the box is a 3D object. <br>
|
|
If the dimensions are the same, an arbitrary algorithm/hypothesis
|
|
will be used. This means that an edge shared by two faces each having
|
|
its own different sub-mesh, will be meshed using algorithms and
|
|
hypotheses of any of the two, chosen randomly. This indeterminacy can
|
|
be fixed by defining \ref mesh_order_anchor "Sub-mesh priority".
|
|
<br>
|
|
|
|
\n Construction of a sub-mesh consists of:
|
|
<ul>
|
|
<li>Selecting a mesh which will encapsulate your sub-mesh</li>
|
|
<li>Selecting a geometrical object for meshing</li>
|
|
<li>Applying one or several previously described
|
|
\ref about_hypo_page "hypotheses" and
|
|
\ref basic_meshing_algos_page "meshing algorithms" which will be used
|
|
at computation of this sub-mesh</li>
|
|
</ul>
|
|
|
|
<br><em>To construct a sub-mesh:</em>
|
|
\par
|
|
From the \b Mesh menu select <b>Create Sub-mesh</b> or click <em>"Create
|
|
Sum-mesh"</em> button in the toolbar.
|
|
|
|

|
|
<center><em>"Create Sub-mesh" button</em></center>
|
|
|
|
\par
|
|
The following dialog box will appear:
|
|
|
|
\image html createmesh-inv2.png
|
|
|
|
\par
|
|
It allows to define the \b Name, the parent \b Mesh and the \b
|
|
Geometry (e.g. a face if the parent mesh has been built on box) of the
|
|
sub-mesh. You can define algorithms and hypotheses in the same way as
|
|
in \ref constructing_meshes_page "Create mesh" menu.
|
|
|
|
\par
|
|
In the Object Browser the structure of the new sub-mesh will be
|
|
displayed as follows:
|
|

|

|
|
It contains:
|
|
<ul>
|
|
<li>a reference to the geometrical object on the basis of which the sub-mesh has been constructed;</li>
|
|
<li><b>Applied hypotheses</b> folder containing the references to the
|
|
hypotheses applied to the construction of the sub-mesh;</li>
|
|
<li><b>Applied algorithms</b> folder containing the references to the
|
|
algorithms applied to the construction of the sub-mesh.</li>
|
|
</ul>
|
|
|
|
<br><b>See Also</b> a sample TUI Script of a
|
|
\ref tui_construction_submesh "Construct Sub-mesh" operation.
