Detailed Description

template<int dim, int dimworld>
class Dune::StructuredGridFactory< AlbertaGrid< dim, dimworld > >

specialization of the generic StructuredGridFactory for AlbertaGrid

The simplex grid generated by the default StructuredGridFactory is not compatible with the Alberta vertex numbering. This might lead to infinite recursions when refining such grid. This specialization of the StructuredGridFactory solves this issue by

1. generating a structured cube grid
2. subdividing each cube into 2 (2d) or 6 (3d) simplices following a compatible numbering scheme for AlbertaGrid.

inlinestatic

Create a structured simplex grid for AlbertaGrid.

This works in dimensions 1-3. Each cube is split into into dim! simplices by constructing macro triangulation, see insertElement for the local simplex numbering.

Parameters

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

createSimplexGrid() [2/2]

template<int dim, int dimworld>

static void Dune::StructuredGridFactory< AlbertaGrid< dim, dimworld > >::createSimplexGrid ( GridFactory< GridType > &  factory, const FieldVector< ctype, dimworld > &  lowerLeft, const FieldVector< ctype, dimworld > &  upperRight, const std::array< unsigned int, dim > &  elements  )

inlinestatic

Create a structured simplex grid for AlbertaGrid.

This works in dimensions 1-3. Each cube is split into into dim! simplices by constructing macro triangulation, see insertElement for the local simplex numbering.

Parameters

factory	Grid factory used for creating the grid
lowerLeft	Lower left corner of the grid
upperRight	Upper right corner of the grid
elements	Number of elements in each coordinate direction
