Adaptation

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.

See more at CAO boundary.

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

The exhaustive description of HOMARD can be read into its documentation. It can be reached by the general help button.

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.

  • 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.
