assembleMultithreaded()

template<class Traits >

template<std::size_t i, class AssembleElementFunc >

void Dumux::PQ1BubbleFreeFlowCouplingManager< Traits >::assembleMultithreaded ( Dune::index_constant< i >  domainId, AssembleElementFunc &&  assembleElement  ) const

inline

Execute assembly kernel in parallel.

Parameters

domainI	the domain index of domain i
assembleElement	kernel function to execute for one element

attachSolution()

template<class Traits >

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

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  )

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

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

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

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)

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.
