Detailed Description

template<int dim, int dimworld = Alberta::dimWorld>
class Dune::AlbertaGrid< dim, dimworld >

[ provides Dune::Grid ]

simplicial grid imlementation from the ALBERTA finite element toolbox

AlbertaGrid provides access to the grid from the ALBERTA finite element toolbox through the Dune interface.

ALBERTA is a finite element toolbox written by Alfred Schmidt and Kunibert G. Siebert (see http://www.alberta-fem.de). It contains a simplicial mesh in 1, 2 and 3 space dimensions that can be dynamically adapted by a bisection algorithm.

Supported ALBERTA versions include 2.0 or higher. It can be downloaded from the ALBERTA website (www.alberta-fem.de). After installing ALBERTA, just configure DUNE with the –with-alberta option and provide the path to ALBERTA.

Each program linking to ALBERTA only supports a fixed dimension of world. This is obtained from the ALBERTA_DIM preprocessor variable, which defaults to WORLDDIM.

Further installation instructions can be found here: http://www.dune-project.org/external_libraries/install_alberta.html

If you use automake and want to compile a program maude, the following Makefile.am snippet might help:

bin_PROGRAMS = maude
 
ALBERTA_DIM = 2
 
maude_SOURCES = maude.cc
maude_CPPFLAGS = $(AM_CPPFLAGS) $(ALBERTA_CPPFLAGS)
maude_LDFLAGS = $(AM_LDFLAGS) $(ALBERTA_LDFLAGS) $(DUNE_LDFLAGS)
maude_LDADD = $(ALBERTA_LIBS) $(DUNE_LIBS)

This will compile and link your program with the world dimension specified by WORLDDIM. If you want to use different world dimensions per program, you can use the following snippet in your Makefile.am:

bin_PROGRAMS = maude2d maude3d
 
maude2d_SOURCES = maude.cc
maude2d_CPPFLAGS = $(AM_CPPFLAGS) $(ALBERTA2D_CPPFLAGS)
maude2d_LDFLAGS = $(AM_LDFLAGS) $(ALBERTA2D_LDFLAGS) $(DUNE_LDFLAGS)
maude2d_LDADD = $(ALBERTA2D_LIBS) $(DUNE_LIBS)
 
maude3d_SOURCES = maude.cc
maude3d_CPPFLAGS = $(AM_CPPFLAGS) $(ALBERTA3D_CPPFLAGS)
maude3d_LDFLAGS = $(AM_LDFLAGS) $(ALBERTA3D_LDFLAGS) $(DUNE_LDFLAGS)
maude3d_LDADD = $(ALBERTA3D_LIBS) $(DUNE_LIBS)

In either case the preprocessor variables HAVE_ALBERTA, which tells you whether ALBERTA was found by configure, and ALBERTA_DIM which tells you the dimension of world for this program.

For further details look into the alberta.m4 autoconf snippet.

Member Function Documentation

◆ adapt()

template<int dim, int dimworld>

bool Dune::AlbertaGrid< dim, dimworld >::adapt

inline

Refine all positive marked leaf entities, coarsen all negative marked entities if possible.

\return true if a least one entity was refined

The complete adaptation process works as follows:

- mark entities with the mark() method
- call preAdapt()
- if preAdapt() returned true: possibly save current solution
- call adapt()
- if adapt() returned true: possibly interpolate the (saved) solution
- call postAdapt()

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.

◆ getMark() [1/2]

int Dune::Grid< dim, dimworld, Alberta::Real , AlbertaGridFamily< dim, Alberta::dimWorld > >::getMark ( const typename Codim< 0 >::Entity & e ) const

returns adaptation mark for given entity

Parameters

[in] e Entity for which adaptation mark should be determined

Returns: int adaptation mark currently set for given Entity e

◆ getMark() [2/2]

bool Dune::Grid< dim, dimworld, Alberta::Real , AlbertaGridFamily< dim, Alberta::dimWorld > >::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, Alberta::Real , AlbertaGridFamily< dim, Alberta::dimWorld > >::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 ).

Dune::AlbertaGrid::mark
bool mark(int refCount, const typename Traits::template Codim< 0 >::Entity &e)
Marks an entity to be refined/coarsened in a subsequent adapt.
Definition: albertagrid.cc:383

Dune::Codim
Static tag representing a codimension.
Definition: dimension.hh:22

This template method will vanish due to the inheritance rules.
