### *class* ansys.meshing.prime.AutoNodeMoveParams(model=None, quality\_measure=None, target\_quality=None, dihedral\_angle=None, n\_iterations\_per\_node=None, restrict\_boundary\_nodes\_along\_surface=None, n\_attempts=None, json\_data=None, \*\*kwargs)

Parameters used to improve volume mesh by auto node move.

**Parameters:**

**model: Model**

Model to create a `AutoNodeMoveParams` object with default parameters.

**quality\_measure: CellQualityMeasure, optional**

Specify cell quality measure to be used for volume mesh improvement. The default value for cell quality measure is skewness.

**target\_quality: float, optional**

Specify target quality used for the mesh improvement based on specified quality measure.

**dihedral\_angle: float, optional**

Dihedral angle used to maintain features of boundary face zonelets.

**n\_iterations\_per\_node: int, optional**

Number of iterations per node to be moved.

**restrict\_boundary\_nodes\_along\_surface: bool, optional**

Option to restrict the movement of the boundary node to the plane containing the boundary faces sharing the boundary node.

**n\_attempts: int, optional**

Number of attempts to improve specified quality measure by node movement.

**json\_data: dict, optional**

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

### Examples

```pycon
>>> auto_node_move_params = prime.AutoNodeMoveParams(model = model)

```
