attachSolution()

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

inlineprotectedinherited

Attach a solution vector stored outside of this class.

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() [1/2]

template<class MDTraits >

template<std::size_t i, class Assembler >

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

inline

Methods to be accessed by the assembly.

prepares all data and variables that are necessary to evaluate the residual (called from the local assembler)

bindCouplingContext() [2/2]

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

inlineinherited

prepares all data and variables that are necessary to evaluate the residual of the element of domain i

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

couplingContext()

template<class MDTraits >

template<std::size_t i>

const auto & Dumux::FreeFlowMomentumPorousMediumCouplingManager< MDTraits >::couplingContext ( Dune::index_constant< i >  domainI, const FVElementGeometry< i > &  fvGeometry, const SubControlVolumeFace< i >  scvf  ) const

inline

Access the coupling context needed for the Stokes domain.

inline

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

Parameters

domainI	the domain index of domain i
elementI	the coupled element of domain í
scvI	the sub-control volume of domain i
domainJ	the domain index of domain j

couplingStencil() [2/3]

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

inlineinherited

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
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

couplingStencil() [3/3]

inlineinherited

evaluate additional derivatives of the element residual of a domain with respect to dofs in the same domain that are not in the regular stencil (see CouplingManager::extendJacobianPattern)

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() [1/2]

template<class MDTraits >

template<class LocalAssemblerI , std::size_t j>

decltype(auto) Dumux::FreeFlowMomentumPorousMediumCouplingManager< MDTraits >::evalCouplingResidual ( Dune::index_constant< freeFlowMomentumIndex >  domainI, const LocalAssemblerI &  localAssemblerI, const SubControlVolume< freeFlowMomentumIndex > &  scvI, Dune::index_constant< j >  domainJ, std::size_t  dofIdxGlobalJ  ) const

inline

evaluate the coupling residual special interface for fcstaggered methods

evalCouplingResidual() [2/2]

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

evaluates the element residual of a coupled element of domain i which depends on the variables at the degree of freedom with index dofIdxGlobalJ of domain j

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

extend the jacobian pattern of the diagonal block of domain i by those entries that are not already in the uncoupled pattern

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 List:

if you overload this also implement evalAdditionalDomainDerivatives

A tuple of shared pointers to the sub problems

updateCoupledVariables()

inlineinherited

update variables of domain i that depend on variables in domain j after the coupling context has been updated

Parameters

domainI	the index of domain i

elemVolVars	the element volume variables (all volume 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()

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

inlineinherited

Updates the entire solution vector, e.g. before assembly or after grid adaption Overload might want to overload function if the solution vector is stored outside this class to make sure updates don't happen more than once.
