Detailed Description

template<class GridType>
class Dune::BemppStructuredGridFactory< GridType >

Construct structured cube and simplex grids in unstructured grid managers.

Note

Copied from Dune and slightly modified:

• Grids embedded in higher-dimensional spaces are supported. In this case the last (dimworld - dim) coordinates of all vertices, where dim is the grid dimension and dimworld the world dimension, are set to zero.
• Automatic pointers (std::auto_ptr) instead of shared pointers (Dune::shared_ptr) are returned.

template<class GridType >

static std::auto_ptr<GridType> Dune::BemppStructuredGridFactory< GridType >::createCubeGrid ( const FieldVector< ctype, dim > &  lowerLeft, const FieldVector< ctype, dim > &  upperRight, const array< int, dim > &  elements  )

inlinestatic

Create a structured cube grid.

Parameters

lowerLeft	Lower left corner of the grid
upperRight	Upper right corner of the grid
elements	Number of elements in each coordinate direction

template<class GridType >

static std::auto_ptr<GridType> Dune::BemppStructuredGridFactory< GridType >::createSimplexGrid ( const FieldVector< ctype, dim > &  lowerLeft, const FieldVector< ctype, dim > &  upperRight, const array< int, dim > &  elements  )

inlinestatic

Create a structured simplex grid.

This works in all dimensions. The Coxeter-Freudenthal-Kuhn triangulation is used, which splits each cube into dim! simplices. See Allgower and Georg, 'Numerical Path Following' for a description.
