### *class* ansys.meshing.prime.MorphBCParams(model=None, morph\_region\_method=None, morphable\_layers=None, morph\_region\_box\_extension=None, json\_data=None, \*\*kwargs)

MorphBCParams contains the input parameters for calculating the boundary conditions for a morphing problem.

**Parameters:**

**model: Model**

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

**morph\_region\_method: BCsVolumetricModality, optional**

Indicate options to identify morphable regions in the input volumetric mesh.

**morphable\_layers: int, optional**

Number of layers around defined boundary.

**morph\_region\_box\_extension: float, optional**

Percentage extension for the volumetric box.

**json\_data: dict, optional**

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

### Examples

```pycon
>>> morph_bcparams = prime.MorphBCParams(model = model)

```
