 Last update: 17.07.2025 

#### *static* SmoothDihedralFaceNodesParams.set\_default(min\_dihedral\_angle=None, tolerance=None, type=None)

Set the default values of SmoothDihedralFaceNodesParams.

- **Parameters:****min\_dihedral\_angle: float, optional**: Minimum angle to be used to identify dihedral faces.
    
    **tolerance: float, optional**: Tolerance relative to local mesh size to control smooth movement of nodes.
    
    **type: SmoothType, optional**: Option to inflate neighbor nodes of dihedral face edges or smooth dihedral face edge nodes to improve dihedral angle.
