simpeg.electromagnetics.base.BaseEMSrc.evalDeriv#

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

Return derivative of the magnetic and electric source terms with respect to the model.

Parameters:

simulationsimpeg.electromagnetics.base.BaseEMSimulation: An instance of an electromagnetic simulation
vnp.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.
