\page import_algos_page Use Existing Elements Algorithms
|
|
|
|
\n <em>Use Existing Elements </em>algorithms allow to define the mesh of a geometrical
|
|
object by the importing suitably located mesh elements from another
|
|
mesh. The mesh elements to import from the other mesh are to be contained in
|
|
groups. If several groups are used to mesh one geometry, validity of
|
|
nodal connectivity of result mesh must be assured by connectivity of
|
|
the source mesh; no geometrical checks are performed to merge
|
|
different nodes at same locations.
|
|
<br> The source elements must totally cover the meshed geometry.
|
|
The source elements lying partially over the geometry will not be used.
|
|
<br>
|
|
These algorithms can be used to mesh a very complex geometry part by
|
|
part, by storing meshes of parts in files and then fusing them
|
|
together using these algorithms.

<b>Use Existing 1D Elements</b> algorithm allows to define the mesh of
|
|
a geometrical edge (or group of edges)
|
|
by importing mesh edges contained in a group (or groups) from another mesh.
|
|
\n To apply this algorithm select the edge to be meshed (indicated in
|
|
the field \b Geometry of <b>Create mesh</b> dialog box),
|
|
<b>Use existing 1D elements</b> in the list of 1D algorithms and click the
|
|
<em>"Add Hypothesis"</em> button.
|
|
The following dialog box will appear:

|
|
|
|
In this dialog box you can define
|
|
<ul>
|
|
<li>The \b Name of the algorithm. </li>
|
|
<li>The <b>Groups of Edges</b> to import 1D elements from.
|
|
<li>The <b>To copy mesh</b> checkbox is to import not only the edges of
|
|
the selected <b>Groups of Edges</b> but to copy the whole source
|
|
mesh. In this case <b>To copy groups</b>, if checked, forces creating
|
|
the same groups as in the imported source mesh.</li>
|
|
</ul>
|
|
|
|
<b>Use Existing 2D Elements</b> algorithm allows to define the mesh of
|
|
a geometrical face (or group of faces)
|
|
by importing mesh faces contained in a group (or groups) from another mesh.
|
|
\n To apply this algorithm select the geometrical face to be meshed (indicated in
|
|
the field \b Geometry of <b>Create mesh</b> dialog box),
|
|
<b>Use existing 2D elements</b> in the list of 2D algorithms and click the
|
|
<em>"Add Hypothesis"</em> button.

In this dialog box you can define
