◆ CouplingManager()

template<class Traits >

Dumux::CouplingManager< Traits >::CouplingManager ( )

inline

The coupling manager stores pointers to the sub-solution vectors. Note that they can be either owning pointers (default updateSolution) or non-owning. In the non-owning case attach the solution vector managed elsewhere using attachSolution and make sure that object stays alive of the lifetime of the coupling manager.

Member Function Documentation

◆ attachSolution()

template<class Traits >

void Dumux::CouplingManager< Traits >::attachSolution ( SolutionVectorStorage & curSol )

inlineprotected

Note: The caller has to make sure that curSol stays alive for the lifetime of the coupling manager. Otherwise we have a dangling reference here. Use with care.

◆ bindCouplingContext()

template<class Traits >

template<std::size_t i, class Assembler >

void Dumux::CouplingManager< Traits >::bindCouplingContext	(	Dune::index_constant< i >	domainI,
		const Element< i > &	elementI,
		const Assembler &	assembler
	)

inline

Parameters

domainI	the domain index of domain i
elementI	the element whose residual we are assemling next
assembler	the multidomain assembler for access to all data necessary for the assembly of all domains

Note: this concerns all data that is used in the evaluation of the element residual and depends on one of the degrees of freedom returned by CouplingManager::couplingStencil; every coupled element residual depends at least on the solution of another domain, that why we always store a copy of the solution vector in the coupling manager, hence, in case the element residual only depends on primary variables of the other domain this function does nothing; overload this function in case the element residual depends on more than the primary variables of domain j

◆ couplingStencil()

template<class Traits >

template<std::size_t i, std::size_t j>

const CouplingStencilType< i, j > & Dumux::CouplingManager< Traits >::couplingStencil	(	Dune::index_constant< i >	domainI,
		const Element< i > &	elementI,
		Dune::index_constant< j >	domainJ
	)		const

inline

Parameters

domainI	the domain index of domain i
elementI	the coupled element of domain í
domainJ	the domain index of domain j

Note: The element residual definition depends on the discretization scheme of domain i box: a container of the residuals of all sub control volumes cc : the residual of the (sub) control volume fem: the residual of the element; This function has to be implemented by all coupling managers for all combinations of i and j

◆ curSol() [1/2]

template<class Traits >

template<std::size_t i>

SubSolutionVector & Dumux::CouplingManager< Traits >::curSol ( Dune::index_constant domainIdx )

inlineprotected

Parameters

domainIdx The domain index

Note: in case of numeric differentiation the solution vector always carries the deflected solution

◆ curSol() [2/2]

template<class Traits >

template<std::size_t i>

const SubSolutionVector & Dumux::CouplingManager< Traits >::curSol ( Dune::index_constant domainIdx ) const

inlineprotected

Parameters

domainIdx The domain index

Note: in case of numeric differentiation the solution vector always carries the deflected solution

◆ evalAdditionalDomainDerivatives()

template<class Traits >

template<std::size_t i, class LocalAssemblerI , class JacobianMatrixDiagBlock , class GridVariables >

void Dumux::CouplingManager< Traits >::evalAdditionalDomainDerivatives	(	Dune::index_constant< i >	domainI,
		const LocalAssemblerI &	localAssemblerI,
		const typename LocalAssemblerI::LocalResidual::ElementResidualVector &	origResiduals,
		JacobianMatrixDiagBlock &	A,
		GridVariables &	gridVariables
	)

inline

Note: Such additional dependencies can arise from the coupling, e.g. if a coupling source term depends on a non-local average of a quantity of the same domain

◆ extendJacobianPattern()

template<class Traits >

template<std::size_t id, class JacobianPattern >

void Dumux::CouplingManager< Traits >::extendJacobianPattern	(	Dune::index_constant< id >	domainI,
		JacobianPattern &	pattern
	)		const

inline

Note: per default we do not add such additional dependencies; Such additional dependencies can arise from the coupling, e.g. if a coupling source term depends on a non-local average of a quantity of the same domain

Warning: if you overload this also implement evalAdditionalDomainDerivatives

◆ numericEpsilon()

template<class Traits >

template<std::size_t i>

decltype(auto) Dumux::CouplingManager< Traits >::numericEpsilon	(	Dune::index_constant< i >	,
		const std::string &	paramGroup
	)		const

inline

◆ problem()

template<class Traits >

template<std::size_t i>

const Problem & Dumux::CouplingManager< Traits >::problem ( Dune::index_constant domainIdx ) const

inline

Parameters

domainIdx The domain index We avoid exception handling here because the performance of this function is critical

◆ setSubProblem()

template<class Traits >

template<class SubProblem , std::size_t i>

void Dumux::CouplingManager< Traits >::setSubProblem	(	std::shared_ptr< SubProblem >	problem,
		Dune::index_constant< i >	domainIdx
	)

inline

Parameters

problem	a pointer to the sub problem
domainIdx	the domain index of the sub problem

◆ setSubProblems()

template<class Traits >

template<typename... SubProblems>

void Dumux::CouplingManager< Traits >::setSubProblems ( const std::tuple< std::shared_ptr< SubProblems >... > & problems )

inline

Parameters

problems A tuple of shared pointers to the sub problems

◆ updateCoupledVariables()

template<class Traits >

template<std::size_t i, class LocalAssemblerI , class UpdatableElementVolVars , class UpdatableFluxVarCache >

void Dumux::CouplingManager< Traits >::updateCoupledVariables	(	Dune::index_constant< i >	domainI,
		const LocalAssemblerI &	localAssemblerI,
		UpdatableElementVolVars &	elemVolVars,
		UpdatableFluxVarCache &	elemFluxVarsCache
	)

inline

Parameters

domainI	the index of domain i
localAssemblerI	the local assembler assembling the element residual of an element of domain i
elemVolVars	the element volume variables (all volume variables in the element local stencil) to be updated
elemFluxVarsCache	the element flux variable cache (all flux variables in the element local stencil) to be updated

Note: Such variables do not necessarily exist and then this function does nothing (default); some examples from geomechanics: the porosity of (physical) domain i (porous medium flow) depends on the displacement vector of physical domain j (mechanics) from domaindecomposition: the transmissibilities for fluxes of domain i to domain j depend on the permeability in domain j (which might depend in turn on the primary variables of domain i)

◆ updateSolution()
