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
-
dim | specifies the dimension of the grid. |
dimworld | specifies the dimension of the surrounding space, this can be different from dim, if the grid is defined on a manifold . |
ct | field type of the world vector space. |
GridFamily | traits class providing all types associated with the grid implementation. |
template<int dim, int dimworld, class ct , class GridFamily >
typedef GridFamily::Traits::HierarchicIterator Dune::Grid< dim, dimworld, ct, GridFamily >::HierarchicIterator |
A type that is a model of Dune::HierarchicIterator A type of iterator that allows to examine, but not to modify, entities of codimension 0 that result from refinement of an entity of codimension 0.
template<int dim, int dimworld, class ct , class GridFamily >
typedef GridFamily::Traits::LevelIntersectionIterator Dune::Grid< dim, dimworld, ct, GridFamily >::LevelIntersectionIterator |
A type that is a model of Dune::IntersectionIterator which is an iterator that allows to examine, but not to modify, the intersections of codimension 1 of an element (entity of codimension 0) with other elements on the same level.
template<int dim, int dimworld, class ct , class GridFamily >
bool Dune::Grid< dim, dimworld, ct, GridFamily >::adapt |
( |
| ) |
|
|
inline |
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()
template<int dim, int dimworld, class ct , class GridFamily >
void Dune::Grid< dim, dimworld, ct, GridFamily >::globalRefine |
( |
int |
refCount | ) |
|
|
inline |
Refine the grid refCount times using the default refinement rule.
This behaves like marking all elements for refinement and then calling preAdapt, adapt and postAdapt. The state after globalRefine is comparable to the state after postAdapt.
template<int dim, int dimworld, class ct , class GridFamily >
template<class DataHandle >
bool Dune::Grid< dim, dimworld, ct, GridFamily >::loadBalance |
( |
DataHandle & |
data | ) |
|
|
inline |
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 describe by CommDataHandleIf just like the data handle for the communicate methods. |
- Returns
- True if the grid has changed.
template<int dim, int dimworld, class ct , class GridFamily >
void Dune::Grid< dim, dimworld, ct, GridFamily >::postAdapt |
( |
| ) |
|
|
inline |
To be called after grid has been adapted and information left over by the adaptation has been processed.
This removes the isNew flags of the elements from the last adapt call.
