SimPEG.electromagnetics.time_domain.sources.BaseTDEMSrc.evalDeriv#

BaseTDEMSrc.evalDeriv(simulation, time, v=None, adjoint=False)[source]#

Derivative of magnetic and electric source terms time a vector at a given time

Parameters:
simulationSimPEG.electromagnetics.base.BaseTDEMSimulation

An instance of a time-domain electromagnetic simulation

time

The time at which you want to compute the derivative

vnumpy.ndarray

A vector

adjointbool

If True, return the adjoint operation

Returns:
tuple

A tuple (s_mDeriv, s_eDerive). If v is not None, the method returns the derivatives of the magnetic and electric sources times the vector v. If v is None, the method returns the functions for multiplying the derivatives with a vector.
