### *class* ansys.meshing.prime.RefineAtContactsParams(model=None, contact\_tolerance=None, relative\_tolerance=None, refine\_max\_size=None, project\_on\_geometry=None, json\_data=None, \*\*kwargs)

Parameters to refine face elements in contact.

- **Parameters:**
    
    **model: Model**: Model to create a `RefineAtContactsParams` object with default parameters.
    
    **contact\_tolerance: float, optional**: Maximum tolerance used to identify face elements as contacts.
    
    **relative\_tolerance: bool, optional**: Option to specify the contact tolerance is relative or absolute.
    
    **refine\_max\_size: float, optional**: Maximum size used to refine contact face elements.
    
    **project\_on\_geometry: bool, optional**: Project on geometry on remesh.
    
    **json\_data: dict, optional**: JSON dictionary to create a `RefineAtContactsParams` object with provided parameters.

### Examples

```pycon
&gt;&gt;&gt; refine_at_contacts_params = prime.RefineAtContactsParams(model = model)

```
