Typedefs
using	GradTensorType
	We're working with 4D tensors to represent the 10 independent components we're solving for, but we only take 2D spatial derivatives, so we define these mixed-dimension tensors for gradients and fluxes.

Functions
void	fluxes (gsl::not_null< FluxTensorType * > flux, const tnsr::I< ComplexDataVector, 2 > &alpha, const GradTensorType &field_gradient)
	The first-order flux \(F^i=\alpha^i \partial_i \Psi_m\).
void	fluxes_on_face (gsl::not_null< FluxTensorType * > flux, const tnsr::I< ComplexDataVector, 2 > &alpha, const tnsr::I< DataVector, 2 > &face_normal_vector, const tnsr::aa< ComplexDataVector, 3 > &field)
	The first-order flux on an element face \(F^i=\alpha^i n_i \Psi_m\).
void	add_sources (gsl::not_null< tnsr::aa< ComplexDataVector, 3 > * > source, const tnsr::aaBB< ComplexDataVector, 3 > &beta, const tnsr::aaBB< ComplexDataVector, 3 > &gamma_rstar, const tnsr::aaBB< ComplexDataVector, 3 > &gamma_theta, const tnsr::aa< ComplexDataVector, 3 > &field, const GradTensorType &field_gradient)
	The source term \(\beta_{ab}^{cd} (\Psi_m)_{cd} + \gamma_{iab}^{cd} \partial_i (\Psi_m)_{cd}\).

FluxTensorType

using GrSelfForce::FluxTensorType

Initial value:

 
    TensorMetafunctions::prepend_spatial_index<tnsr::aa<ComplexDataVector, 3>,
                                               2, UpLo::Up, Frame::Inertial>

We're working with 4D tensors to represent the 10 independent components we're solving for, but we only take 2D spatial derivatives, so we define these mixed-dimension tensors for gradients and fluxes.

GradTensorType

Initial value:

 
    TensorMetafunctions::prepend_spatial_index<tnsr::aa<ComplexDataVector, 3>,
                                               2, UpLo::Lo, Frame::Inertial>
