simpeg.electromagnetics.time_domain.sources.MagDipole.hInitial

MagDipole.hInitial(simulation)

Compute initial magnetic field.

Note that we compute analytic vector potential and take numerical curl so that B is divergence-free before converting to H-field.

Parameters:

simulationBaseTDEMSimulation

A SimPEG TDEM simulation

Returns:

numpy.ndarray

Initial magnetic field
