The component for handling the CCE evolution and waveform output.
The DataBox associated with the CharacteristicEvolution will contain many spin-weighted volume tags associated with the ongoing CCE computation, as well as storage for the boundary values and quantities related to managing the evolution.
Metavariables requirements:
Initialization
Evolve
evolved_coordinates_variables_tag
: A Tags::Variables
with real-valued tensors associated with coordinates that must be evolved.evolved_swsh_tag
: The spin-weighted quantity to be evolved (typically BondiJ
).evolved_swsh_dt_tag
: The spin-weighed quantity associated that is to act as the time derivative to evolve evolved_swsh_tag
(typically BondiH
).cce_boundary_communication_tags
: A typelist of tags that will be communicated between the worldtube boundary component and the extraction component (typically Cce::Tags::characteristic_worldtube_boundary_tags<Tags::BoundaryValue>
)cce_gauge_boundary_tags
: A typelist of tags that will be derived via GaugeAdjustedBoundaryValue
and corresponding gauge utilitiescce_integrand_tags
: A typelist of tags needed as inputs to the linear solve. Obtainable from the metafunction Cce::integrand_terms_to_compute_for_bondi_variable
.cce_integration_independent_tags
: A typelist of tags that are to be computed and stored for each hypersurface iteration, but have no dependencies on the intermediate hypersurface steps (typically Cce::pre_computation_steps
).cce_temporary_equations_tags
: A typelist of temporary buffers maintained for intermediate steps in the integrand equations. Obtainable from the metafunction Cce::integrand_terms_to_compute_for_bondi_variable
.cce_pre_swsh_derivatives_tags
: A typelist of inputs to spin-weighted derivative calculations to compute and cache for intermediate steps of the CCE calculation. (typically Cce::all_pre_swsh_derivative_tags
)cce_swsh_derivative_tags
: A typelist of spin-weighted derivatives to compute and cache for intermediate steps of the CCE calculation. (typically Cce::all_swsh_derivative_tags
)cce_transform_buffer_tags
: A typelist of spin-weighted spherical harmonic transform modes used to compute the spin-weighted derivatives in the modal representation. (typically Cce::all_transform_buffer_tags
).cce_angular_coordinate_tags
: A typelist of real-valued angular coordinates that are not evolved.cce_scri_tags
: the tags of quantities to compute at scri+cce_hypersurface_initialization
: a mutator (for use with Actions::MutateApply
) that is used to compute the initial hypersurface data from the boundary data.
