### *class* ansys.meshing.prime.FixInvalidNormalNodeParams(model=None, nugget\_size=None, nugget\_mesh\_size=None, label=None, json\_data=None, \*\*kwargs)

Parameters to fix invalid average face normal at nodes by creating a nugget.

**Parameters:**

**model: Model**

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

**nugget\_size: float, optional**

Relative size used to create nugget at invalid normal node. The size is relative to mesh size at the node.

**nugget\_mesh\_size: float, optional**

Relative size used as max size to mesh nugget created at invalid normal node. The size is relative to mesh size at the node.

**label: str, optional**

Label to set on new face zonelets created.

**json\_data: dict, optional**

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

### Examples

```pycon
>>> fix_invalid_normal_node_params = prime.FixInvalidNormalNodeParams(model = model)

```
