#### SizeControl.set\_curvature\_sizing\_params(params)

Set the curvature sizing parameters to compute volumetric size field.

- **Parameters:**
    
    **params**: Parameters that enables you to set the normal angle as the maximum allowable angle at which one element edge may span.
- **Returns:**
    
    [`SetSizingResults`](ansys.meshing.prime.SetSizingResults.md#ansys.meshing.prime.SetSizingResults): Return the SetSizingResults.
- **Return type:**
    
    [`SetSizingResults`](ansys.meshing.prime.SetSizingResults.md#ansys.meshing.prime.SetSizingResults)

### Examples

```pycon
&gt;&gt;&gt; size_control.set_curvature_sizing_params(
&gt;&gt;&gt;                  prime.CurvatureSizingParams(model=model,
&gt;&gt;&gt;                  min = 0.1, max = 1.0, growth_rate = 1.2,
&gt;&gt;&gt;                  normal_angle = 18))

```
