Coupling of several regular DuMux problems. More...

Description

Coupling of several regular DuMux problems.

The multi domain module allows coupling regular DuMux 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.
 
 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.

const LocalAssemblerI &  localAssemblerI,
Dune::index_constant< j >  domainJ,
std::size_t  dofIdxGlobalJ 
) const
inline

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
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

)
inline

updates all data and variables that are necessary to evaluate the residual of the element of domain i this is called whenever one of the primary variables that the element residual depends on changes in domain j

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 udpate 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
