Member Function Documentation

adapt() [1/2]

bool Dune::ALU3dGrid< elType, Comm >::adapt ( )

inherited

Refine all positive marked leaf entities, coarsen all negative marked entities if possible.

\return true if a least one entity was refined

The complete adaptation process works as follows:

- mark entities with the mark() method
- call preAdapt()
- if preAdapt() returned true: possibly save current solution
- call adapt()
- if adapt() returned true: possibly interpolate the (saved) solution
- call postAdapt()

adapt() [2/2]

bool Dune::ALU3dGrid< elType, Comm >::adapt ( AdaptDataHandleInterface< GridImp, DataHandle > &  handle )

inlineinherited

Refine all positive marked leaf entities, coarsen all negative marked entities if possible.

\return true if a least one entity was refined

The complete adaptation process works as follows:

- mark entities with the mark() method
- call preAdapt()
- if preAdapt() returned true: possibly save current solution
- call adapt()
- if adapt() returned true: possibly interpolate the (saved) solution
- call postAdapt()

Parameters

handle

handler for restriction and prolongation operations which is a Model of the AdaptDataHandleInterface class.

comm()

const CollectiveCommunication & Dune::ALU3dGrid< elType, Comm >::comm ( ) const

inlineinherited

return const reference to a collective communication object. The return type is a model of Dune::CollectiveCommunication.

communicate()

void Dune::ALU3dGrid< elType, Comm >::communicate ( CommDataHandleIF< DataHandleImp, DataTypeImp > &  data, InterfaceType  iftype, CommunicationDirection  dir, int  level  ) const

inherited

Communicate information on distributed entities on a given level Template parameter is a model of Dune::CommDataHandleIF.

Parameters

data	A data handle telling the method what data is communicated and how this should be done.
interface	The communication interface to use.
dir	The direction of the communication along the interface (forward or backward.
level	The index of the grid level where the communication should happen.

getMark() [1/2]

int Dune::Grid< dim, dimworld, alu3d_ctype , ALU3dGridFamily< elType, Comm > >::getMark ( const typename Codim< 0 >::Entity &  e ) const

inlineinherited

returns adaptation mark for given entity

Parameters

[in]

e

Entity for which adaptation mark should be determined

Returns

int adaptation mark currently set for given Entity e

getMark() [2/2]

int Dune::ALU3dGrid< elType, Comm >::getMark ( const typename Traits::template Codim< 0 >::Entity &  e ) const

inlineinherited

returns adaptation mark for given entity

Parameters

[in]

e

Entity for which adaptation mark should be determined

Returns

int adaptation mark currently set for given Entity e

loadBalance()

bool Dune::ALU3dGrid< elType, Comm >::loadBalance ( DataHandle &  data )

inlineinherited

Calculates load of each process and repartition the grid if neccessary. For parameters of the load balancing process see the README file of the ALUGrid package.

Parameters

data

the data handler class that must implement three methods: // calls data inline on macro element. From there the data of // all children can be written to the message buffer. // MessageBufferImp implements the MessageBufferIF interface. template<class MessageBufferImp> void inlineData ( MessageBufferImp& buff, Dune::Entity<0> & e); // calls data xtract on macro element. From there the data of // all children can be restored from the message buffer. // numChildren is the number of all children underneath the // macro element e. // MessageBufferImp implements the MessageBufferIF interface. template<class MessageBufferImp> void xtractData ( MessageBufferImp& buff, Dune::Entity<0> & e, size_t numChildren ); // This method is called at the end of the load balancing process // before adaptation markers are removed. Here the user can apply // a data compression or other features. This method can be // empty if nothing should be done. void compress ();

mark() [1/3]

bool Dune::Grid< dim, dimworld, alu3d_ctype , ALU3dGridFamily< elType, Comm > >::mark ( int  refCount, const typename Codim< 0 >::Entity &  e  )

inlineinherited

Marks an entity to be refined/coarsened in a subsequent adapt.

Parameters

[in]	refCount	Number of subdivisions that should be applied. Negative value means coarsening.
[in]	e	Entity that should be marked

Returns

true if Entity was marked, false otherwise.

mark() [2/3]

bool Dune::GridDefaultImplementation< dim, dimworld, alu3d_ctype , ALU3dGridFamily< elType, Comm > >::mark ( int  refCount, const typename Traits ::template Codim< 0 >::Entity &  e  )

inlineinherited

Marks an entity to be refined/coarsened in a subsequent adapt.

Parameters

[in]	refCount	Number of subdivisions that should be applied. Negative value means coarsening.
[in]	e	Entity to Entity that should be refined

Returns

true if Entity was marked, false otherwise.

Note

• default implementation is: return false; for grids with no adaptation.
• for the grid programmer: this method is implemented as a template method, because the Entity type is not defined when the class is instantiated You won't need this trick in the implementation. In your implementation you should use it as

  bool mark( int refCount,
             typename Traits::template Codim<0>::Entity & e ).

  This template method will vanish due to the inheritance rules.

mark() [3/3]

bool Dune::ALU3dGrid< elType, Comm >::mark ( int  refCount, const typename Traits::template Codim< 0 >::Entity &  e  )

inlineinherited

Marks an entity to be refined/coarsened in a subsequent adapt.

Parameters

[in]	refCount	Number of subdivisions that should be applied. Negative value means coarsening.
[in]	e	Entity that should be marked

Returns

true if Entity was marked, false otherwise.
