Detailed Description
class Dune::YaspGrid< dim, Coordinates >
[ provides Dune::Grid ]
Provides a distributed structured cube mesh.
YaspGrid stands for yet another structured parallel grid. It implements the dune grid interface for structured grids with arbitrary overlap (including zero), periodic boundaries, and a fast implementation allowing on-the-fly computations.
YaspGrid supports three coordinate modes: EquidistantCoordinates, EquidistantOffsetCoordinates, and Dune::TensorProductCoordinates.
- Template Parameters
-
dim The dimension of the grid and its surrounding world Coordinates The coordinate mode of the grid.
- Examples
- recipe-blocking.cc, recipe-communication.cc, recipe-geometry-grid.cc, recipe-grid-function-operations.cc, recipe-integrating-grid-functions.cc, recipe-integration.cc, recipe-iterate-over-grid.cc, recipe-linear-system-assembly.cc, recipe-linear-system-solution-istl.cc, recipe-linear-system-solution-pdelab.cc, and recipe-operator-splitting.cc.

◆ 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)Marks an entity to be refined/coarsened in a subsequent adapt.Definition: yaspgrid.hh:1277
◆ mark() [3/3]
|
inline |
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
- On yaspgrid marking one element will mark all other elements of the level as well
- If refCount is lower than refCount of a previous mark-call, nothing is changed
