Coupling of several regular DuMu^x problems. More...

Description

The multi domain module allows coupling regular DuMu^x problems. Several coupling modes are currently available.

Modules
	Boundary coupling mode
	Couples problems of different or equal dimension that touch at the domain boundary. Examples are equal-dimension multi-physics problems like Darcy-Stokes coupling or PNM (pore network model)-Darcy coupling.

	Coupling for dual network approach for pore network models
	Coupling for dual network approach for pore network models.

	Embedded mixed-dimension coupling mode
	Couples problems of different dimensions where one or more lower-dimensional problems (lowdim) are embedded in a higher-dimensional domain (bulk). Examples are embedded one-dimensional networks for the simulation of blood tissue perfusion, or root-soil interaction, and embedded fracture models.

	Conforming mixed-dimension facet coupling mode
	Couples problems of different dimensions where one or more lower-dimensional problems (lowdim) live on the facets of the higher-dimensional domain (bulk). Examples are discrete facet conforming fracture models and problems with physics on a domain surface.

◆ evalCouplingResidual()

template<class Traits >

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

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

inline

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
