Mesh module provides the possibility to perform different adaptations of a mesh.
|
|
To refine the mesh means to cut out elements indicated according to indications provided by the user.

HOMARD
|
|
######
|
|
|
|
HOMARD can treat meshes into 2 or 3 dimensions and comprising the following elements:
|
|
- mesh-points
|
|
- segments
|
|
- triangles
|
|
- quadrangles
|
|
- tetrahedra
|
|
- hexahedra
|
|
- prisms
|
|
|
|
These elements can be present simultaneously. For example, HOMARD will be able to adapt a comprising mesh of the triangles and the quadrangles.
|
|
|
|
To start operation, select **Remesh with HOMARD** item in **Adaptation** menu.

|
|
* **Mesh In** is the initial mesh to remesh.
|
|
* **Mesh Out** is the resulting mesh after remeshing. By default, the name of the initial mesh is kept and the file name is based on the name of the initial mesh.
|
|
* **Conformity type** is a choice between **Conformal** and **Non conformal**.
|
|
* **Boundary type** is a choice between **No boundary**, **CAO** and **Non CAO**.
|
|
|
|
- If the choice is **CAO**, a XAO file is required for each CAO boundary creation.

|
|
|
|
- If the choice is **Non CAO**, some discrete and/or analytical boundaries can be created.

MG_Adapt
|
|
########
|
|
|
|
For meshes made of triangles and/or tetrahedra, remeshing operations are available with the MG-Adapt plugin. The remeshing is based on wanted mesh sizes defined over the mesh or as a constant. The boundaries are dedeuced from the initial mesh.
|
|
|
|
To start **Remeshing** operation, select **Remesh with MG_Adapt** item in **Adaptation** menu.
|
|
|
|

:align: center
|
|
|
|
|
|
* **Mesh In** is the initial mesh to remesh.
|
|
* **Mesh Out** is the resulting mesh after remeshing. By default, the name of the initial mesh is kept and the file name is based on the name of the initial mesh.
|
|
* **Size map definition** is a choice between **Local**, **Background** and **Constant**.
|
|
|
|
- If the choice is **Background**, the name of the MED file must be given.
|
|
- If the choice is **Local** or **Background**, the name of the field must be selected from the list, together with time step.
