### *class* ansys.meshing.prime.WrapperPatchFlowRegionsParams(model=None, base\_size=None, suggested\_part\_name=None, number\_of\_threads=None, dead\_regions=None, sizing\_method=None, size\_field\_ids=None, patch\_at\_live=None, json\_data=None, \*\*kwargs)

WrapperPatchFlowRegionsParams to define parameters for patch flow regions operation.

**Parameters:**

**model: Model**

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

**base\_size: float, optional**

Base size to define octree.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**suggested\_part\_name: str, optional**

Suggested part name for created patching surfaces.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**number\_of\_threads: int, optional**

Number of threads for multithreading.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**dead\_regions: List\[DeadRegion\], optional**

List of dead regions.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**sizing\_method: SizeFieldType, optional**

Method used to define sizing method for patching.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**size\_field\_ids: Iterable\[int\], optional**

Ids used to define size field based octree refinement.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**patch\_at\_live: bool, optional**

Creates patches closer to live instead of dead.   
**This is a beta parameter**. **The behavior and name may change in the future**.

**json\_data: dict, optional**

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

### Examples

```pycon
>>> wrapper_patch_flow_regions_params = prime.WrapperPatchFlowRegionsParams(model = model)

```
