Detailed Description

template<typename Metavariables>
struct Initialization::Actions::TimeStepperHistory< Metavariables >

Initialize time-stepper items.

DataBox changes:

• Adds:
  • db::add_tag_prefix<Tags::dt, variables_tag>
  • Tags::StepperError<variables_tag>
  • Tags::HistoryEvolvedVariables<variables_tag, dt_variables_tag>
  • Tags::ComputeDeriv (for non-conservative systems)
  • Tags::ComputeDiv (for conservative systems)
• Removes: nothing
• Modifies: nothing

Note

HistoryEvolvedVariables is allocated, but needs to be initialized

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.
