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)[source]#

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:

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
