simpeg.electromagnetics.static.resistivity.sources.Dipole#

class simpeg.electromagnetics.static.resistivity.sources.Dipole(receiver_list, location_a=None, location_b=None, location=None, current=1.0)[source]#

Bases: BaseSrc

Dipole source

Parameters:

receiver_listlist of simpeg.electromagnetics.static.resistivity.receivers.BaseRx: A list of DC/IP receivers
location_a(dim) array_like: A electrode locations; remember to set location_b keyword argument to define B electrode location.
location_b(dim) array_like: B electrode locations; remember to set location_a keyword argument to define A electrode location.
locationtuple of array_like, optional: A and B electrode locations. If location_a and location_b are provided, don’t pass values to this argument. Otherwise, provide a tuple of the form (location_a, location_b).
currentfloat, optional: Current amplitude in \(A\) that goes through each electrode.

Attributes

`current`	Amplitudes of the source currents
`location`	locations of the source electrodes
`location_a`	Locations of the A-electrodes
`location_b`	Locations of the B-electrodes
`nD`	Number of data associated with the source.
`receiver_list`	List of receivers associated with the source
`uid`	Universal unique identifier
`vnD`	Vector number of data.

Methods

`eval`(sim)	Discretize sources to mesh
`evalDeriv`(sim)	Returns the derivative of the source term with respect to the model.
`get_receiver_indices`(receivers)	Get indices for a subset of receivers within the source's receivers list.
