### *class* ansys.meshing.prime.VolumetricSizeFieldComputeParams(model=None, enable\_multi\_threading=None, enable\_periodicity=None, periodic\_params=None, growth\_rate\_lower\_bound=None, json\_data=None, \*\*kwargs)

Parameters associated with the compute volumetric size field operation.

- **Parameters:**
    
    **model: Model**: Model to create a `VolumetricSizeFieldComputeParams` object with default parameters.
    
    **enable\_multi\_threading: bool, optional**: Option to compute volumetric size field in parallel using multithreads.
    
    **enable\_periodicity: bool, optional**: Option to enable periodic size field computations.
    
    **periodic\_params: SFPeriodicParams, optional**: Periodic parameters to compute the size field.
    
    **growth\_rate\_lower\_bound: float, optional**: Lower bound for growth rate.   
    **This is a beta parameter**. **The behavior and name may change in the future**.
    
    **json\_data: dict, optional**: JSON dictionary to create a `VolumetricSizeFieldComputeParams` object with provided parameters.

### Examples

```pycon
&gt;&gt;&gt; volumetric_size_field_compute_params = prime.VolumetricSizeFieldComputeParams(model = model)
