SimPEG.electromagnetics.frequency_domain.sources.LineCurrent

class SimPEG.electromagnetics.frequency_domain.sources.LineCurrent(receiver_list=None, frequency=None, location=None, current=1.0, mu=1.25663706212e-06, **kwargs)

Bases: BaseFDEMSrc

Line current source.

Given the wire path provided by the (n_loc, 3) locations array, the cells intersected by the wire path are identified and integrated source terms are computed.

Parameters:

receiver_listlist of SimPEG.electromagnetics.frequency_domain.receivers.BaseRx

List of FDEM receivers

frequencyfloat

Source frequency

location(n,3) numpy.ndarray

Array defining the node locations for the wire path. For inductive sources, you must close the loop.

currentfloat, optional

Strength of the current.

mufloat, optional

Magnetic permeability to use.

Attributes

current	Source current
location	Line current nodes locations
n_segments	The number of line current segments.
