◆ leafAllSubDomainInterfacesBegin()

template<typename HostGrid_ , typename MDGridTraitsType >

LeafAllSubDomainInterfacesIterator Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::leafAllSubDomainInterfacesBegin ( ) const

inline

Returns an iterator over all subdomain interfaces on the leaf view.

This method returns an iterator that will visit all pairwise surface interfaces between subdomains on the leaf view. In particular, given to adjacent cells \(e_1\) and \(e_2\) and two subdomains \(s_1\) and \(s_2\), this iterator will visit the intersection between \(e_1\) and \(e_2\) iff all of the following hold:

\begin{eqnarray*} e_1 \in s_1,\ e_1 \not\in s_2,\\ e_2 \not\in s_1,\ e_1 \in s_2.\end{eqnarray*}

In essence, the two subdomains have to be locally disjoint on \(e_1\) and \(e_2\).

The iterator will only traverse the host grid once for visiting all subdomain interfaces. Incrementing the iterator might thus result in an iterator pointing to the same grid intersection, but to a different pair of subdomains. The subdomains pointed to by the iterator can be retrieved by calling LeafAllSubDomainInterfacesIterator::subDomain1() and LeafAllSubDomainInterfacesIterator::subDomain2(), respectively.

◆ leafAllSubDomainInterfacesEnd()

	)		const

inline

Returns an iterator over the leaf interface of two subdomains.

The resulting iterator will visit all cell intersections that are part of both subdomains.

Attention: The iterator assumes the two subdomains to be non-overlapping! If there is an overlap, some intersections will be iterated over twice!

Parameters

inline

Returns an iterator over all subdomain interfaces on the requested level view.

This method returns an iterator that will visit all pairwise surface interfaces between subdomains on the requested level view. In particular, given to adjacent cells \(e_1\) and \(e_2\) and two subdomains \(s_1\) and \(s_2\), this iterator will visit the intersection between \(e_1\) and \(e_2\) iff all of the following hold:

\begin{eqnarray*} e_1 \in s_1,\ e_1 \not\in s_2,\\ e_2 \not\in s_1,\ e_1 \in s_2.\end{eqnarray*}

In essence, the two subdomains have to be locally disjoint on \(e_1\) and \(e_2\).

The iterator will only traverse the host grid once for visiting all subdomain interfaces. Incrementing the iterator might thus result in an iterator pointing to the same grid intersection, but to a different pair of subdomains. The subdomains pointed to by the iterator can be retrieved by calling LevelAllSubDomainInterfacesIterator::subDomain1() and LevelAllSubDomainInterfacesIterator::subDomain2(), respectively.

◆ maxAssignedSubDomainIndex()

template<typename HostGrid_ , typename MDGridTraitsType >

SubDomainIndex Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::maxAssignedSubDomainIndex ( ) const

inline

Returns the largest subdomain index that was ever assigned to a cell in this grid.

This method returns the largest subdomain index that was passed to addToSubDomain() or assignToSubDomain() since this MultiDomainGrid was created. Keep in mind that the subdomain belonging to that index might not contain any entities anymore if all entities have been removed from it at a later point.

◆ maxLevel()

template<typename HostGrid_ , typename MDGridTraitsType >

int Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::maxLevel ( ) const

inline

The current maximum level of the grid.

◆ maxSubDomainIndex()

template<typename HostGrid_ , typename MDGridTraitsType >

const SubDomainIndex Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::maxSubDomainIndex ( ) const

inline

The largest allowed index for a subdomain.

Note: As subdomain indices always start at 0, this also determines the maximum number of possible subdomains.

clears the saved state of the subdomain layout that was active before the last call to updateSubDomains().

◆ preUpdateSubDomains()

template<typename HostGrid_ , typename MDGridTraitsType >

void Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::preUpdateSubDomains ( )

inline

Calculates the new subdomain layout, but does not update the current subdomains yet.

After calling this method, you can query the grid for the changes that will occur when the new subdomain layout becomes active. This includes the possibility to obtain the new indices entities will be assigned in the modified subdomains.

To switch the grid over to the new layout, call updateSubDomains().

◆ removeFromAllSubDomains()

template<typename HostGrid_ , typename MDGridTraitsType >

void Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::removeFromAllSubDomains ( const typename Traits::template Codim< 0 >::Entity & e )

Removes the given leaf entity from all subdomains it currently belongs to.

void Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::removeFromSubDomain	(	SubDomainIndex	subDomain,

Removes the given leaf entity from the specified subdomain.

◆ startSubDomainMarking()

template<typename HostGrid_ , typename MDGridTraitsType >

void Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::startSubDomainMarking ( )

inline

Prepares the grid for (re-)assigning cells to subdomains.

After calling this method, it becomes possible to invoke the various methods for cell assignment to subdomains. When you are done marking, call preUpdateSubDomains().

IMPORTANT: Reassigning subdomains and grid adaptation are mutually exclusive, it is not possibly to do both at the same time. This restriction is enforced by the grid.

◆ subDomain() [1/2]

template<typename HostGrid_ , typename MDGridTraitsType >

SubDomainGrid & Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::subDomain ( SubDomainIndex subDomain )

inline

Returns a reference to the SubDomainGrid associated with the given subdomain.

◆ subDomain() [2/2]

template<typename HostGrid_ , typename MDGridTraitsType >

const SubDomainGrid & Dune::mdgrid::MultiDomainGrid< HostGrid_, MDGridTraitsType >::subDomain ( SubDomainIndex subDomain ) const

Returns a reference to the SubDomainGrid associated with the given subdomain.
