Public Types
using	const_global_cache_tags = implementation defined
	Tags for constant items added to the GlobalCache. These items are initialized from input file options.

using	mutable_global_cache_tags = implementation defined
	Tags for mutable items added to the GlobalCache. These items are initialized from input file options.

using	argument_tags = implementation defined
	Tags for items fetched by the DataBox and passed to the apply function.

using	simple_tags_from_options = implementation defined
	Tags for simple DataBox items that are initialized from input file options.

using	default_initialized_simple_tags = implementation defined
	Tags for simple DataBox items that are default initialized.

using	return_tags = implementation defined
	Tags for items in the DataBox that are mutated by the apply function.

using	simple_tags = implementation defined
	Tags for mutable DataBox items that are either default initialized or initialized by the apply function.

using	compute_tags = time_stepper_ref_tags< TimeStepperBase >
	Tags for immutable DataBox items (compute items or reference items) added to the DataBox.

	Given the items fetched from a DataBox by the argument_tags, when not using LTS, mutate the items in the DataBox corresponding to return_tags.

Detailed Description

template<typename Metavariables, typename TimeStepperBase>
struct Initialization::TimeStepping< Metavariables, TimeStepperBase >

Initialize items related to time stepping.

Details

See the type aliases defined below for what items are added to the GlobalCache and DataBox and how they are initialized

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

The documentation for this struct was generated from the following file:

src/Evolution/Initialization/Evolution.hpp
