SimPEG.electromagnetics.static.resistivity.sources.Dipole#

class SimPEG.electromagnetics.static.resistivity.sources.Dipole(receiver_list, location_a=None, location_b=None, location=None, **kwargs)[source]#

Bases: BaseSrc

Dipole source

Parameters:

receiver_listlist of SimPEG.electromagnetics.static.resistivity.receivers.BaseRx: A list of DC/IP receivers
location_a(n_source, dim) numpy.array_like: A electrode locations; remember to set ‘location_b’ keyword argument to define N electrode locations.
location_b(n_source, dim) numpy.array_like: B electrode locations; remember to set ‘location_a’ keyword argument to define M electrode locations.
locationlist or tuple of length 2 of numpy.array_like: A and B electrode locations. In this case, do not set the ‘location_a’ and ‘location_b’ keyword arguments. And we supply a list or tuple of the form [location_a, location_b].

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.
