simpeg.electromagnetics.frequency_domain.Simulation3DCurrentDensity.getRHSDeriv#

Simulation3DCurrentDensity.getRHSDeriv(freq, src, v, adjoint=False)[source]#

Derivative of the right-hand side times a vector for a given source and frequency.

The right-hand side for each source is constructed according to:

q=iωseiωCMeμ1sm

where

  • C is the discrete curl operator

  • sm and se are the integrated magnetic and electric source terms, respectively

  • Meμ is the inner-product matrices for permeabilities projected to edges

See the Notes section of the doc strings for Simulation3DCurrentDensity for a full description of the formulation.

Where m are the set of model parameters and v is a vector, this method returns

qkmv

Or the adjoint operation

qkmTv
Parameters:
freqint

The frequency in Hz.

srcfrequency_domain.sources.BaseFDEMSrc

The FDEM source object.

vnumpy.ndarray

The vector. (n_param,) for the standard operation. (n_faces,) for the adjoint operation.

adjointbool

Whether to perform the adjoint operation.

Returns:
numpy.ndarray

Derivative of the right-hand sides times a vector. (n_faces,) for the standard operation. (n_param,) for the adjoint operation.
