### *class* ansys.meshing.prime.IGAUnstructuredSplineSolid(model=None, id=None, degree=None, invalid\_jacobian\_elements\_count=None, json\_data=None, \*\*kwargs)

Information of unstructured spline solid.

- **Parameters:**
    
    **model: Model**: Model to create a `IGAUnstructuredSplineSolid` object with default parameters.
    
    **id: int, optional**: Id of the unstructured spline solid.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **degree: int, optional**: Degree of the spline solid.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **invalid\_jacobian\_elements\_count: int, optional**: Count of elements with negative jacobian.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **json\_data: dict, optional**: JSON dictionary to create a `IGAUnstructuredSplineSolid` object with provided parameters.

### Examples

```pycon
>>> iga_unstructured_spline_solid = prime.IGAUnstructuredSplineSolid(model = model)

```
