mymesh.improvement.TetImprove

mymesh.improvement.TetImprove(M, h, schedule='scfS', repeat=1, labels=None, smoother='SmartLaplacianSmoothing', smooth_kwargs={}, verbose=True, FeatureAngle=25, ContractIter=5)

Tetrahedral mesh quality improvement using multiple local operations.

Parameters:

• M (mymesh.mesh) – Tetrahedral mesh to be improved

• h (float) – Target element size/edge length

• schedule (str, optional) –

  Order of operations to perform, specified as a string with each character indicating an operation, by default ‘scfS’.

  Possible operations:

  • ’s’ - Splitting (TetSplit())

  • ’c’ - Contraction (TetContract())

  • ’f’ - Flipping (TetFlip())

  • ’S’ - Smoothing

• repeat (int, optional) – Number of times to repeat the schedule, by default 1

• labels (str, array_like, or NoneType, optional) – Element labels indicating different regions. If specified, region interfaces will be preserved. This can be specified as an array_like with M.NElem entries or a string corresponding to an entry in M.ElemData, by default None.

• smoother (str, optional) – Specify which smoothing operation to use, by default ‘SmartLaplacianSmoothing’

• smooth_kwargs (dict, optional) – Key word arguments to be passed to the smoother, by default {}

• verbose (bool, optional) – If True, will display progress, by default True

• FeatureAngle (int, optional) – FeatureAngle : int, optional Angle (in degrees) used to identify features, by default 25. See DetectFeatures() for more information., by default 25

• ContractIter (int, optional) – Maximum number of iterations to perform in the contraction step, by default 5

Returns:

Mnew – Tetrahedral mesh after quality improvement

Return type:
