◆ advectiveFluxCoupling()

template<class MDTraits >

template<std::size_t i>

Scalar Dumux::DarcyDarcyBoundaryCouplingManager< MDTraits >::advectiveFluxCoupling	(	Dune::index_constant< i >	domainI,
		const Element< i > &	element,
		const FVElementGeometry< i > &	fvGeometry,
		const ElementVolumeVariables< i > &	elemVolVars,
		const SubControlVolumeFace< i > &	scvf,
		int	phaseIdx = `0`
	)		const

inline

This is the method for the case where the Neumann condition is potentially solution dependent

Parameters

domainI	the domain index for which to compute the flux
element	The finite element
fvGeometry	The finite-volume geometry
elemVolVars	All volume variables for the element
scvf	The sub control volume face
phaseIdx	the phase for which to compute the flux

Negative values mean influx. E.g. for the mass balance that would the mass flux in \( [ kg / (m^2 \cdot s)] \).

compute alpha := n^T*K*g

◆ attachSolution()

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

inlineprotectedinherited

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()

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

inlineinherited

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 MDTraits >

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

const CouplingStencil & Dumux::DarcyDarcyBoundaryCouplingManager< MDTraits >::couplingStencil	(	Dune::index_constant< i >	domainI,
		const Element< i > &	element,
		Dune::index_constant< j >	domainJ
	)		const

inline

returns an iterable container of all indices of degrees of freedom of domain j that couple with / influence the element residual of the given element of domain i

Parameters

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

◆ curSol() [1/2]

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

inlineprotectedinherited

Parameters

domainIdx The domain index

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

◆ curSol() [2/2]

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

inlineprotectedinherited

Parameters

domainIdx The domain index

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

◆ evalAdditionalDomainDerivatives()

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

inlineinherited

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

◆ evalCouplingResidual()

decltype(auto) Dumux::CouplingManager< MDTraits >::evalCouplingResidual	(	Dune::index_constant< i >	domainI,
		const LocalAssemblerI &	localAssemblerI,
		Dune::index_constant< j >	domainJ,
		std::size_t	dofIdxGlobalJ
	)		const

inlineinherited

Parameters

domainI	the domain index of domain i
localAssemblerI	the local assembler assembling the element residual of an element of domain i
domainJ	the domain index of domain j
dofIdxGlobalJ	the index of the degree of freedom of domain j which has an influence on the element residual of domain i

Note: the element whose residual is to be evaluated can be retrieved from the local assembler as localAssemblerI.element() as well as all up-to-date variables and caches.; the default implementation evaluates the complete element residual if only parts (i.e. only certain scvs, or only certain terms of the residual) of the residual are coupled to dof with index dofIdxGlobalJ the function can be overloaded in the coupling manager

Returns: the element residual

◆ extendJacobianPattern()

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

inlineinherited

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

◆ init()

template<class MDTraits >

void Dumux::DarcyDarcyBoundaryCouplingManager< MDTraits >::init	(	std::shared_ptr< Problem< domainIdx< 0 >()> >	problem0,
		std::shared_ptr< Problem< domainIdx< 1 >()> >	problem1,
		const SolutionVector &	curSol
	)

inline

template<class MDTraits >

template<std::size_t i>

scvf	the sub control volume face

◆ numericEpsilon()

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

inlineinherited

◆ problem()

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

inlineinherited

Parameters

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

◆ setSubProblem()

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

inlineinherited

Parameters

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

◆ setSubProblems()

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

inlineinherited

Parameters

problems A tuple of shared pointers to the sub problems

◆ updateCoupledVariables()

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

inlineinherited

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)

◆ updateCouplingContext()

void Dumux::CouplingManager< MDTraits >::updateCouplingContext	(	Dune::index_constant< i >	domainI,
		const LocalAssemblerI &	localAssemblerI,
		Dune::index_constant< j >	domainJ,
		std::size_t	dofIdxGlobalJ,
		const PrimaryVariables< j > &	priVarsJ,
		int	pvIdxJ
	)

inlineinherited

Parameters

domainI	the domain index of domain i
localAssemblerI	the local assembler assembling the element residual of an element of domain i
domainJ	the domain index of domain j
dofIdxGlobalJ	the index of the degree of freedom of domain j whose solution changed
priVarsJ	the new solution at the degree of freedom of domain j with index dofIdxGlobalJ
pvIdxJ	the index of the primary variable of domain j which has been updated

Note: this concerns all data that is used in the evaluation of the element residual and depends on the primary variables at the degree of freedom location with index dofIdxGlobalJ; the element whose residual is to be evaluated can be retrieved from the local assembler as localAssemblerI.element(); per default, we update the solution vector, if the element residual of domain i depends on more than the primary variables of domain j update the other dependent data here by overloading this function

◆ updateSolution()

void Dumux::CouplingManager< MDTraits >::updateSolution ( const SolutionVector & curSol )

inlineinherited

◆ volVars()

template<class MDTraits >

template<std::size_t i>

VolumeVariables< i > Dumux::DarcyDarcyBoundaryCouplingManager< MDTraits >::volVars	(	Dune::index_constant< i >	domainI,
		const Element< i > &	element,
		const SubControlVolume< i > &	scv
