Namespaces
namespace	Actions
	Actions related to evolution using implicit-explicit time stepping.
namespace	OptionTags
	Input-file options for IMEX.

	Protocols for imex.

	Tags for IMEX.

Classes
struct	CleanHistory
	Mutator to clean history objects for each sector after an IMEX substep. More...
struct	CleanHistory< System, tmpl::list< ImplicitSectors... > >
	Mutator to clean history objects for each sector after an IMEX substep. More...
struct	GuessExplicitResult
	Mutator for the initial_guess of an implicit sector that does not modify the variables. The initial guess is therefore the result of the explicit step. More...
struct	ImplicitDenseOutput
	Mutator to apply the implicit portion of dense output, intended for use in RunEventsAndDenseTriggers. More...
struct	Initialize
	Create the IMEX structures and options. More...
struct	NoJacobianBecauseSolutionIsAnalytic
	Mutator for the jacobian of an implicit sector that has an analytic solution. Such a sector never does numerical solves, and so does not need an available jacobian. More...
struct	SolveImplicitSector
	Perform the implicit solve for one implicit sector. More...

Typedefs
template<typename IndependentList, typename DependentList>
using	jacobian_tags
	Create a list of all jacobian tags for the dependence of DependentList on IndependentList.

Enumerations
enum class	GuessResult { InitialGuess , ExactSolution }
	Type of guess returned from an implicit sector's initial_guess mutator. If ExactSolution is returned, the implicit solve is skipped.
enum class	Mode { Implicit , SemiImplicit }
	IMEX implementations. More...

jacobian_tags

template<typename IndependentList, typename DependentList>

using imex::jacobian_tags

Initial value:

 tmpl::join<tmpl::transform<
    IndependentList,
    tmpl::lazy::transform<
        tmpl::pin<DependentList>,
        tmpl::defer<tmpl::bind<::imex::Tags::Jacobian, tmpl::parent<tmpl::_1>,
                               tmpl::_1>>>>>

Create a list of all jacobian tags for the dependence of DependentList on IndependentList.

This can be used to construct the argument for a Variables from the tags_lists of two other Variables.
