Detailed Description

template<typename VariablesTag = NoSuchType>
struct Actions::RecordTimeStepperData< VariablesTag >

Records the variables and their time derivatives in the time stepper history.

With dt_variables_tag = db::add_tag_prefix<Tags::dt, variables_tag>:

Uses:

• GlobalCache: nothing
• DataBox:
  • variables_tag (either the provided VariablesTag or the system::variables_tag if none is provided)
  • dt_variables_tag
  • Tags::HistoryEvolvedVariables<variables_tag>
  • Tags::TimeStepId

DataBox changes:

• Adds: nothing
• Removes: nothing
