Detailed Description

template<typename EvolvedCoordinatesVariablesTag, typename EvolvedSwshTag, bool local_time_stepping>
struct Cce::Actions::InitializeCharacteristicEvolutionTime< EvolvedCoordinatesVariablesTag, EvolvedSwshTag, local_time_stepping >

Initializes the contents of the CharacteristicEvolution component for performing the time evolution of the system, which is the singleton that handles the main evolution system for CCE computations.

Details

Sets up the DataBox to be ready to perform the time-stepping associated with the CCE system.

DataBox changes:

• Modifies: nothing
• Adds:
  • Tags::TimeStepId
  • Tags::Next<Tags::TimeStepId>
  • Tags::TimeStep
  • Tags::Time
  • Tags::AdaptiveSteppingDiagnostics
