Meshing

Some calculation codes may require a meshing of the domain (SPPS for example). I-Simpa used the TetGen meshing code (A Quality Tetrahedral Mesh Generator and a 3D Delaunay Triangulator). See the documentation for more information.

Within I-Simpa, TetGen can be paramatrized:

  • ‘Test mesh topology’

    Check/uncheck for activate the debug mode of TetGen (debug mode).

    Warning

    With the debug mode, the meshing is not realized.

  • ‘Additional parameters’

    Add parameters to the TetGen default parameters.

  • ‘Radius/Edge ratio’

    Defines the ratio between the radius of the sphere that would contain a mesh and the lenght of the mesh. This parameter could be useful in order to avoid long meshes.

  • ‘Scene correction before meshing’

    Check/uncheck for trying to repair the 3D scene if possible.

  • ‘User-defined paramters’

    Defines new parameters by replacing default parameters.

  • ‘Surface receiver constraint’.

    Check/uncheck for using a given value of the mesh surface ‘Surface receiver constraint (m²)’.

  • ‘Surface receiver constraint (m²)’

    Maximun accepted value of the mesh surface (m²) for a surface receiver. The value can be modified only if the ‘Surface receiver constraint’ parameter is checked.

  • ‘Volume constraint’

    Check/uncheck for using a given maximum value of the mesh volume ‘Volume constraint (m3)’.

  • ‘Volume constraint (m3)’

    Maximun accepted value of a mesh volume (m3). The value can be modified only if the ‘Volume constraint’ parameter is checked.
