Detailed Description

One-dimensional adaptive grid.

[ provides Dune::Grid ]

This implementation of the grid interface provides one-dimensional grids only. The OneDGrid can be nonuniform and provides local mesh refinement and coarsening.

Member Typedef Documentation

◆ ctype

typedef double Dune::OneDGrid::ctype

The type used to store coordinates.

If you ever want OneDGrid to use a different type for coordinates, you need to change this type and the third template argument of the base class.

Member Enumeration Documentation

◆ RefinementType

The different forms of grid refinement supported by OneDGrid.

Enumerator
LOCAL 

New level consists only of the refined elements.

COPY 

New level consists of the refined elements and the unrefined ones, too.

◆ DUNE_DEPRECATED_MSG()

Dune::Grid< dim, dimworld, double , OneDGridFamily< 1, 1 > >::DUNE_DEPRECATED_MSG ( "entityPointer() is deprecated and will be removed after the release of dune-grid 2.4. Use entity() instead to directly obtain an Entity object."  )
inlineinherited

obtain EntityPointer from EntitySeed.

Deprecated:
This method is deprecated and will be removed after the release of dune-grid 2.4. Please use entity() instead, which will directly return an Entity object that you can then store for later use. The EntityPointer concept in general is deprecated and will not be available after dune-grid 2.4 has been released.

obtain Entity from EntitySeed.

◆ getMark() [1/3]

int Dune::OneDGrid::getMark ( const Traits::Codim< 0 >::Entity e) const

return current adaptation marker of given entity

Parameters
eEntity to the entity you want to mark
Returns
int current adaptation marker of entity pointer e

◆ getMark() [2/3]

int Dune::Grid< dim, dimworld, double , OneDGridFamily< 1, 1 > >::getMark ( const typename Codim< 0 >::Entity e) const
inlineinherited

returns adaptation mark for given entity

Parameters
[in]eEntity for which adaptation mark should be determined
Returns
int adaptation mark currently set for given Entity e

◆ getMark() [3/3]

int Dune::GridDefaultImplementation< dim, dimworld, double , OneDGridFamily< 1, 1 > >::getMark ( const typename Traits::template Codim< 0 >::Entity e) const
inlineinherited

returns adaptation mark for given entity, i.e. here the default implementation returns 0.

Parameters
[in]eEntity for which adaptation mark should be determined
Returns
int adaptation mark, here the default value 0 is returned

◆ globalRefine()

void Dune::OneDGrid::globalRefine ( int  refCount)

Does one uniform refinement step.

Parameters
refCountI don't know what this is good for. It doesn't actually do anything.

◆ mark() [1/3]

bool Dune::OneDGrid::mark ( int  refCount,
const Traits::Codim< 0 >::Entity e 
)

Mark entity for refinement.

Parameters
refCountif >0 mark for refinement, if <0 mark for coarsening
eEntity to the entity you want to mark
Returns
True, if marking was successfull

◆ mark() [2/3]

bool Dune::Grid< dim, dimworld, double , OneDGridFamily< 1, 1 > >::mark ( int  refCount,
const typename Codim< 0 >::Entity e 
)
inlineinherited

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

Parameters
[in]refCountNumber of subdivisions that should be applied. Negative value means coarsening.
[in]eEntity that should be marked
Returns
true if Entity was marked, false otherwise.

◆ mark() [3/3]

bool Dune::GridDefaultImplementation< dim, dimworld, double , OneDGridFamily< 1, 1 > >::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]refCountNumber of subdivisions that should be applied. Negative value means coarsening.
[in]eEntity 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 ).
    bool mark(int refCount, const Traits::Codim< 0 >::Entity &e)
    Mark entity for refinement.
    This template method will vanish due to the inheritance rules.

◆ maxLevel()

int Dune::OneDGrid::maxLevel ( ) const
inline

Return maximum level defined in this grid.

Levels are numbered 0 ... maxlevel with 0 the coarsest level.

◆ numBoundarySegments()

size_t Dune::OneDGrid::numBoundarySegments ( ) const
inline

Return the number of coarse grid boundary segments.

For this grid implementation, the return value is always 2, because only connected domains are supported, and then the coarse grid boundary consists of two points.
