### *class* ansys.meshing.prime.ProximitySizingParams(model=None, min=None, max=None, growth\_rate=None, elements\_per\_gap=None, ignore\_self\_proximity=None, ignore\_orientation=None, json\_data=None, \*\*kwargs)

Size field using proximity size control computes edge and face sizes in gaps using the specified minimum number of element layers.

**Parameters:**

**model: Model**

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

**min: float, optional**

Minimum size used for computing edge and face size using proximity size control.

**max: float, optional**

Maximum size used for computing edge and face size using proximity size control.

**growth\_rate: float, optional**

Growth rate used for transitioning from one element size to neighbor element size.

**elements\_per\_gap: float, optional**

The number of elements per gap can be a real value. This has the effect of stretching face elements with larger sizes along side faces, or gaps, thereby reducing the overall face count, and ultimately the cell count.

**ignore\_self\_proximity: bool, optional**

Ignore proximity within zonelets.

**ignore\_orientation: bool, optional**

The ignore orientation option can be used to ignore the face normal orientation during the proximity calculation. The default is false.

**json\_data: dict, optional**

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

### Examples

```pycon
>>> proximity_sizing_params = prime.ProximitySizingParams(model = model)

```
