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.
