mindelec.geometry.Disk

class mindelec.geometry.Disk(name, center, radius, dtype=np.float32, sampling_config=None)

Definition of Disk object.

Parameters

• name (str) – name of the disk.

• center (Union[tuple[int, float], list[int, float], numpy.ndarray]) – center coordinates of the disk.

• radius (Union[int, float]) – radius of the disk.

• dtype (numpy.dtype) – data type of sampled point data type. Default: numpy.float32.

• sampling_config (SamplingConfig) – sampling configuration. Default: None

Raises

• ValueError – If center is neither list nor tuple of length 2.

• ValueError – If radius is negative.

Supported Platforms:

Ascend

Examples

>>> from easydict import EasyDict as edict
>>> from mindelec.geometry import create_config_from_edict, Disk
>>> disk_mesh = edict({'domain': edict({'random_sampling': False, 'size' : [100, 180]}),
...                    'BC': edict({'random_sampling': False, 'size': 200, 'with_normal' : True,})})
>>> disk = Disk("disk", (-1.0, 0), 2.0, sampling_config=create_config_from_edict(disk_mesh))
>>> domain = disk.sampling(geom_type="domain")
>>> bc, bc_normal = disk.sampling(geom_type="BC")
>>> print(bc.shape)
(200, 2)

sampling(geom_type='domain')

sampling domain and boundary points

Parameters

geom_type (str) – geometry type

Returns

Numpy.array, 2D numpy array with or without boundary normal vectors

Raises

• ValueError – If config is None.

• KeyError – If geom_type is domain but config.domain is None.

• KeyError – If geom_type is BC but config.bc is None.

• ValueError – If geom_type is neither BC nor domain.
