Create Dual Mesh
|
||
|
|
****************
|
||
|
|
|
||
|
|
We can create the dual of a Tetrahedron Mesh which will be a polyhedron mesh.
|
||
|
|
The Mesh is created using MEDCoupling computeDualMesh function.
|
||
|
|
|
||
|
|
*To create a dual mesh:*
|
||
|
|
|
||
|
|
.. |img| image:: ../images/create_dual_mesh_icon.png
|
||
|
|
|
||
|
|
From the contextual menu in the Object Browser of from the **Mesh** menu select
|
||
|
|
**Create Dual Mesh** or click *"Create Dual Mesh"* button |img| in the toolbar.
|
||
|
|
|
||
|
|
The following dialog box will appear:
|
||
|
|
|
||
|
|
.. image:: ../images/create_dual_mesh_dlg.png
|
||
|
|
:align: center
|
||
|
|
|
||
|
|
In the dialog:
|
||
|
|
|
||
|
|
* specify the mesh for which to create the dual mesh:
|
||
|
|
* **Select whole mesh** from the study tree. If a mesh was selected before calling function it will be preselected.
|
||
|
|
* If the mesh is not made of only Tetrahedrons a error message will be displayed and you won't be allowed to go through.
|
||
|
|
* specify the **New Mesh Name**;
|
||
|
|
* activate **Project boundary elements on shape** for the boundary points of the
|
||
|
|
dual mesh to be projected on their associated shape.
|
||
|
|
|
||
|
|
* Click **Apply** or **Apply and Close** button to confirm the operation.

Limitations of the dual mesh
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
Only 2d groups will be transferred to the dual mesh.
|
||
|
|
|
||
|
|
If you have convex shape the projection might not improve the mesh.
