Detailed Description

template<int dimw>
class Dune::ALUConformGrid< 2, dimw >

[ provides Dune::Grid ]

grid with support for simplicial mesh in 2d and 3d.

The ALUConformGrid implements the Dune GridInterface for 2d triangular and 3d tetrahedral meshes. This grid can be locally adapted (conforming) and used in parallel computations using dynamic load balancing.

Note

Adaptive parallel grid supporting dynamic load balancing, written mainly by Bernard Schupp. This grid supports triangular/tetrahedral elements - a 3d cube grid is also available via the grid implementation ALUCubeGrid or ALUSimplexGrid.

(see ALUGrid homepage: http://www.mathematik.uni-freiburg.de/IAM/Research/alugrid/)

• Available Implementations
  • Dune::ALUConformGrid<2,dimw>

For installation instructions see http://www.dune-project.org/external_libraries/install_alugrid.html .

Note

The unspecialized version of ALUConformGrid is defined for documentation purposes only, only the specializations can actually be used.

Deprecated:

Use ALUGrid instead.

inherited

–Leveliterator Iterator to first entity of given codim on level

loadBalance() [1/2]

bool Dune::ALU2dGrid< dim, dimworld, eltype >::loadBalance ( )

inherited

Re-balances the load each process has to handle for a parallel grid,.

Returns

True if the grid has changed.

loadBalance() [2/2]

bool Dune::ALU2dGrid< dim, dimworld, eltype >::loadBalance ( DataHandle &  data )

inherited

Re-balances the load each process has to handle for a parallel grid,.

Returns

True if the grid has changed.

mark() [1/3]

bool Dune::Grid< dim, dimworld, alu2d_ctype , ALU2dGridFamily< dim, dimworld, eltype > >::mark ( int  refCount, const typename Codim< 0 >::Entity &  e  )

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 that should be marked

Returns

true if Entity was marked, false otherwise.

mark() [2/3]

bool Dune::GridDefaultImplementation< dim, dimworld, alu2d_ctype , ALU2dGridFamily< dim, dimworld, eltype > >::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]	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

  bool mark( int refCount,
             typename Traits::template Codim<0>::Entity & e ).

  This template method will vanish due to the inheritance rules.

mark() [3/3]

bool Dune::ALU2dGrid< dim, dimworld, eltype >::mark ( int  refCount, const typename Traits::template Codim< 0 >::Entity &  e  )

inherited

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 that should be marked

Returns

true if Entity was marked, false otherwise.

maxLevel()

int Dune::ALU2dGrid< dim, dimworld, eltype >::maxLevel ( ) const

inherited

Return maximum level defined in this grid. Levels are numbered 0 ... maxLevel with 0 the coarsest level.

nonConform()

bool Dune::ALU2dGrid< dim, dimworld, eltype >::nonConform ( ) const

inlineprotectedinherited

return true if grid allows hanging nodes on leaf level i.e. returns true for ALUSimplexGrid and returns false for ALUConformGrid
