template<class Metavariables>
struct Cce::CharacteristicEvolution< Metavariables >
The component for handling the CCE evolution and waveform output.
Details
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:
- Phases:
- Type aliases:
- evolved_coordinates_variables_tag: A Tags::Variables with real-valued tensors associated with coordinates that must be evolved.
- evolved_swsh_tags: The spin-weighted quantities to be evolved (typically BondiJ).
- evolved_swsh_dt_tags: The spin-weighed quantities associated that are to act as the time derivative to evolve evolved_swsh_tags (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 utilities
- cce_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.
