Detailed Description
class Dune::IdentityGrid< HostGrid >
Provides a meta grid that is identical to its host.
- Template Parameters
-
HostGrid The host grid type wrapped by the IdentityGrid

◆ getMark() [2/2]

Return refinement mark for entity.
- Returns
- refinement mark (1,0,-1)

◆ mark() [2/3]
|
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 typename Traits::template Codim< 0 >::Entity &e)Mark entity for refinement.Definition: identitygrid.hh:318
◆ mark() [3/3]
|
inline |
Mark entity for refinement.
This only works for entities of codim 0. The parameter is currently ignored
- Returns
- true, if marking was successful
- false, if marking was not possible
References Dune::IdentityGrid< HostGrid >::hostgrid_.
◆ maxLevel()
|
inline |
Return maximum level defined in this grid.
Levels are numbered 0 ... maxlevel with 0 the coarsest level.
