Detailed Description

template<int dim, int dimworld, class ct, class GridFamily>
class Dune::Grid< dim, dimworld, ct, GridFamily >

Grid abstract base class.

This class is the base class for all grid implementations. Although no virtual functions are used we call it abstract since its methods do not contain an implementation but forward to the methods of the derived class via the Barton-Nackman trick.

Template parameters:


Exported constants

enum  { dimension = dim }
 A constant that exports the template parameter dim. More...
enum  { dimensionworld = dimworld }
 A constant that exports the template parameter dimworld. More...

Exported types

typedef ct ctype
 Define type used for coordinates in grid module.

Grid id

std::string name () const
 Return the id of the grid.

Size methods

int maxLevel () const

int size (int level, int codim) const
 Return number of grid entities of a given codim on a given level in this process.
int size (int codim) const

template<int cd>
Codim< cd >::template Partition<
All_Partition >::LeafIterator 
leafend () const

 return const reference to the grids level index set for level level
const Codim< 0 >::LeafIndexSet & leafIndexSet () const
 return const reference to the grids leaf index set

Adaptivity and grid refinement

void globalRefine (int refCount)
 Refine the grid refCount times using the default refinement rule.
template<class T>
bool mark (int refCount, T &e)
 Marks an entity to be refined/coarsened in a subsequent adapt.
template<class T>
int getMark (T &e) const
 returns adaptation mark for given entity
bool preAdapt ()
 To be called after entities have been marked and before adapt() is called.
bool adapt ()
 Refine all positive marked leaf entities, coarsen all negative marked entities if possible.
void postAdapt ()
 To be called after grid has been adapted and information left over by the adaptation has been processed.

Parallel data distribution and communication

const Codim< 0 >::CollectiveCommunication & comm () const
 return const reference to a collective communication object. The return type is a model of Dune::CollectiveCommunication.

Public Member Functions

bool loadBalance ()
 Re-balances the load each process has to handle for a parallel grid, if grid has changed , true is returned.
template<class DataHandle>
bool loadBalance (DataHandle &data)
 Re-balances the load each process has to handle for a parallel grid, the DataHandle data works like the data handle for the communicate methods. If grid has changed , true is returned.

Classes

Member Function Documentation

template<int dim, int dimworld, class ct, class GridFamily>
bool Dune::Grid< dim, dimworld, ct, GridFamily >::adapt (  )  [inline]
