#### *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.
