Detailed Description

template<typename Metavariables>
struct Cce::Actions::InitializeCharacteristicEvolutionVariables< Metavariables >

Initializes the main data storage for the CharacteristicEvolution component, which is the singleton that handles the main evolution system for CCE computations.

Details

Sets up the DataBox to be ready to take data from the worldtube component, calculate initial data, and start the hypersurface computations.

DataBox changes:

• Modifies: nothing
• Adds:
  • metavariables::evolved_coordinates_variables_tag

  • db::add_tag_prefix<Tags::dt,
    metavariables::evolved_coordinates_variables_tag>

  • Tags::Variables<metavariables::cce_angular_coordinate_tags>
  • Tags::Variables<metavariables::cce_scri_tags>

  • Tags::Variables<tmpl::append<
    metavariables::cce_integrand_tags,
    metavariables::cce_integration_independent_tags,
    metavariables::cce_temporary_equations_tags>>

  • Tags::Variables<metavariables::cce_pre_swsh_derivatives_tags>
  • Tags::Variables<metavariables::cce_transform_buffer_tags>
  • Tags::Variables<metavariables::cce_swsh_derivative_tags>
  • Spectral::Swsh::Tags::SwshInterpolator< Tags::CauchyAngularCoords>
  • Spectral::Swsh::Tags::SwshInterpolator<Tags::PartiallyFlatAngularCoords>
• Removes: nothing

Note

This action relies on the SetupDataBox aggregated initialization mechanism, so Actions::SetupDataBox must be present in the Initialization phase action list prior to this action.
