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 Function Documentation
◆ getMark() [1/3]
int Dune::OneDGrid::getMark | ( | const Traits::Codim< 0 >::Entity & | e | ) | const |
return current adaptation marker of given entity
- Parameters
-
e Entity to the entity you want to mark
- Returns
- int current adaptation marker of entity pointer e
◆ getMark() [2/3]
|
inlineinherited |
◆ getMark() [3/3]
|
inlineinherited |
returns adaptation mark for given entity, i.e. here the default implementation returns 0.
- Parameters
-
[in] e Entity 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
-
refCount I 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
-
refCount if >0 mark for refinement, if <0 mark for coarsening e Entity to the entity you want to mark
- Returns
- True, if marking was successful
◆ mark() [2/3]
|
inlineinherited |
◆ mark() [3/3]
|
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 typename Traits::template Codim<0>::Entity & e ).bool mark(int refCount, const Traits::Codim< 0 >::Entity &e)Mark entity for refinement.
◆ maxLevel()
|
inline |
Return maximum level defined in this grid.
Levels are numbered 0 ... maxlevel with 0 the coarsest level.
◆ numBoundarySegments()
|
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.
