#### *static* HexCoreParams.set\_default(transition\_size\_field\_type=None, buffer\_layers=None, rel\_peel\_layer\_offset=None, transition\_layer\_type=None, cell\_element\_type=None, surface\_mesh\_size\_scaling=None, enable\_region\_based\_hexcore=None)

Set the default values of the `HexCoreParams` object.

- **Parameters:**
    
    **transition\_size\_field\_type: SizeFieldType, optional**: Size field type to be used for transition volume (volume between hexcore and boundary).
    
    **buffer\_layers: int, optional**: Minimum number of cell layers of the same size before the cell size halves or doubles.
    
    **rel\_peel\_layer\_offset: float, optional**: Gap between hexahedral core and geometry surface relative to the surface mesh size.
    
    **transition\_layer\_type: HexCoreTransitionLayerType, optional**: Handle size transition of hex cells.
    
    **cell\_element\_type: HexCoreCellElementType, optional**: Cell element type of hex-shaped cells.
    
    **surface\_mesh\_size\_scaling: SurfaceMeshSizeScaling, optional**: Setting for scaling surface mesh size for hexcore refinement.
    
    **enable\_region\_based\_hexcore: bool, optional**: Checks whether to enable region based hexcore or not.
