Detailed Description

template<class HG>
class AMDiS::AdaptiveGrid< HG >

Wrapper class for Dune-grids that allows automatic signalling of events during grid adaptation.

Calls to grid.preAdapt(), grid.adapt() and grid.postAdapt() need to be replaced by calls to the corresponding methods of this class to use the automatic update functionality.

Template Parameters

HG	Host grid to be wrapped. Must implement the dune grid interface.

Member Function Documentation

◆ comm()

auto const & comm ( ) const

inline

Return const reference to a collective communication object.

Parallel data distribution and communication

◆ globalIdSet()

auto const & globalIdSet ( ) const

inline

Return const reference to the grids global id set.

Access to index and id sets

◆ globalRefine()

void globalRefine ( int refCount )

inline

Refines all grid elements refCount times.

Adaptivity and grid refinement

References AdaptiveGrid< HG >::adapt(), AdaptiveGrid< HG >::postAdapt(), and AdaptiveGrid< HG >::preAdapt().

◆ lbegin()

auto lbegin ( int level ) const

inline

Iterator to first entity of given codim on level.

Grid iterators

◆ loadBalance() [1/2]

bool loadBalance ( )

inline

Calls loadBalance on the underlying grid.

Re-balances the load each process has to handle for a parallel grid.

Returns: true if the grid has changed.

◆ loadBalance() [2/2]

bool loadBalance ( DataHandle & handle )

inline

Calls loadBalance(handle) on the underlying grid.

Re-balances the load each process has to handle for a parallel grid and moves the data.

Parameters

data	A data handle telling the method which data should be communicated and how. Has to adhere to the interface described by Dune::CommDataHandleIf.

Returns: true if the grid has changed.
