### *class* ansys.meshing.prime.SmoothDihedralFaceNodesParams(model=None, min\_dihedral\_angle=None, tolerance=None, type=None, json\_data=None, \*\*kwargs)

Parameters to smooth dihedral face nodes.

**Parameters:**

**model: Model**

Model to create a `SmoothDihedralFaceNodesParams` object with default 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.

**json\_data: dict, optional**

JSON dictionary to create a `SmoothDihedralFaceNodesParams` object with provided parameters.

### Examples

```pycon
>>> smooth_dihedral_face_nodes_params = prime.SmoothDihedralFaceNodesParams(model = model)

```
