### *class* ansys.meshing.prime.LeakPreventionParams(model=None, material\_points=None, scope=None, max\_hole\_size=None, n\_expansion\_layers=None, json\_data=None, \*\*kwargs)

LeakPreventionParams defines leakage prevention control parameters for wrapper.

- **Parameters:**
    
    **model: Model**: Model to create a `LeakPreventionParams` object with default parameters.
    
    **material\_points: List\[str\], optional**: Material points used for leak prevention control.
    
    **scope: ScopeDefinition, optional**: Scope used for leak prevention control.
    
    **max\_hole\_size: float, optional**: Maximum hole size to prevent leakage into region.
    
    **n\_expansion\_layers: int, optional**: Number of layers to expand leaking region.
    
    **json\_data: dict, optional**: JSON dictionary to create a `LeakPreventionParams` object with provided parameters.

### Examples

```pycon
&gt;&gt;&gt; leak_prevention_params = prime.LeakPreventionParams(model = model)

```
