CheckIntegrity(GUI=False)

class FefloRemeshing(mesh: Mesh, solution=None, levelset=None, metric=None)

Bases: object

Prepro(hmin: float64 = 0.0001, geotol: float64 = 0.0001, rmax: float64 = 1)

Method to preprocess mesh before adaption and get a background surface mesh well oriented using INRIA Gamma3 tool feflo

Parameters:

• hmin (MuscatFloat) – Minimum mesh size allowed

• geotol (MuscatFloat) – Geometric tolerance to compute surface mesh

• rmax (MuscatFloat) – Maximum anisotropic ratio allowed

Returns:

backupMeshName – name of the file (without extension) of feflo resulting surface mesh to ensure geometry accuracy during adaptation

Return type:

str

Runner(remesher_options: dict, backEndOptions: dict)

Run the process to write mesh in an inria mesh file, launch feflo and read the resulting mesh

Notes

The inria mesh file (called temp_name) will be written in a temporary directory

Parameters:

• remesher_options (dict) – keys corresponding to feflo option name and value corresponding to value if applicable

• backEndOptions (dict) –

  Extra options for the “by file” feflo communication. Supported keys include:

  • "temp_name": name of the output mesh file without extension. Defaults to "temp_file".

  • "binary": whether to write binary files. Defaults to True.

  • "prefix": prefix used when restoring tags. Defaults to "feflo".

  • "keep_temp_files": whether to keep temporary files. Defaults to False.

  • "temp_dir": directory used for temporary files. If None, a temporary directory is used.

Returns:

mesh – feflo resulting mesh from adaption

Return type:

Mesh
