mindelec.geometry.GeometryWithTime

class mindelec.geometry.GeometryWithTime(geometry, timedomain, sampling_config=None)

Definition of geometry with time.

Parameters

• geometry (Geometry) – geometry

• timedomain (TimeDomain) – time domain

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

Raises

ValueError – If sampling_config is not None but sampling_config.time is None .

Supported Platforms:

Ascend

sampling(geom_type='domain')

sampling 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.

• KeyError – If geom_type is IC but config.ic is None.

• ValueError – If geom_type is not BC, IC nor domain.
