### *class* ansys.meshing.prime.MultiZoneSizingParams(model=None, max\_size=None, min\_size=None, growth\_rate=None, use\_volumetric\_size\_field=None, json\_data=None, \*\*kwargs)

Parameters for MultiZone meshing.

**Parameters:**

**model: Model**

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

**max\_size: float, optional**

Defines global maximum mesh size.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**min\_size: float, optional**

Defines global minimum mesh size.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**growth\_rate: float, optional**

Defines growth rate.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**use\_volumetric\_size\_field: bool, optional**

Defines whether to use size field for MultiZone meshing.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**json\_data: dict, optional**

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

### Examples

```pycon
>>> multi_zone_sizing_params = prime.MultiZoneSizingParams(model = model)

```
