Detailed Description

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

Initialize items related to time, such as the time step.

Since we have not started the evolution yet, we initialize the state before the initial time. So Tags::TimeStepId is undefined at this point, and Tags::Next<Tags::TimeStepId> is the initial time.

DataBox changes:

• Adds:
  • Tags::TimeStepId
  • Tags::Next<Tags::TimeStepId>
  • Tags::TimeStep
  • Tags::Time
• 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.
