◆ 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
domainIthe domain index for which to compute the flux
elementThe finite element
fvGeometryThe finite-volume geometry
elemVolVarsAll volume variables for the element
scvfThe sub control volume face
phaseIdxthe 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 ( 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
domainIthe domain index of domain i
elementIthe element whose residual we are assemling next
assemblerthe 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
domainIthe domain index of domain i
elementthe coupled element of domain í
domainJthe domain index of domain j

◆ curSol() [1/2]

SubSolutionVector< i > & Dumux::CouplingManager< MDTraits >::curSol ( Dune::index_constant< i >  domainIdx)
inlineprotectedinherited
Parameters
domainIdxThe domain index
Note
in case of numeric differentiation the solution vector always carries the deflected solution

◆ curSol() [2/2]

const SubSolutionVector< i > & Dumux::CouplingManager< MDTraits >::curSol ( Dune::index_constant< i >  domainIdx) const
inlineprotectedinherited
Parameters
domainIdxThe 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
domainIthe domain index of domain i
localAssemblerIthe local assembler assembling the element residual of an element of domain i
domainJthe domain index of domain j
dofIdxGlobalJthe 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,

scvfthe sub control volume face

◆ problem()

const Problem< i > & Dumux::CouplingManager< MDTraits >::problem ( Dune::index_constant< i >  domainIdx) const
inlineinherited
Parameters
domainIdxThe domain index We avoid exception handling here because the performance of this function is critical

◆ setSubProblem()

Dune::index_constant< i >  domainIdx 
)
inlineinherited

◆ updateCoupledVariables()

void Dumux::CouplingManager< MDTraits >::updateCoupledVariables ( Dune::index_constant< i >  domainI,
const LocalAssemblerI &  localAssemblerI,
UpdatableElementVolVars &  elemVolVars,
UpdatableFluxVarCache &  elemFluxVarsCache 
)
inlineinherited
Parameters
domainIthe index of domain i
localAssemblerIthe local assembler assembling the element residual of an element of domain i
elemVolVarsthe element volume variables (all volume variables in the element local stencil) to be updated
elemFluxVarsCachethe 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
domainIthe domain index of domain i
localAssemblerIthe local assembler assembling the element residual of an element of domain i
domainJthe domain index of domain j
dofIdxGlobalJthe index of the degree of freedom of domain j whose solution changed
priVarsJthe new solution at the degree of freedom of domain j with index dofIdxGlobalJ
pvIdxJthe 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
