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:
