Detailed Description

template<class D>
class Dune::RefinedSimplexLocalBasis< D, 2 >

Base class for LocalBasis classes based on uniform refinement in 2D; provides numbering and local coordinates of subelements.

Shape functions like these are necessary for hierarchical error estimators for certain nonlinear problems.

Template Parameters

D	Type to represent the field in the domain.

Member Function Documentation

getSubElement() [1/2]

template<class D >

static int Dune::RefinedSimplexLocalBasis< D, 2 >::getSubElement ( const FieldVector< D, 2 > &  global )

inlinestaticprotected

Get the number of the subtriangle containing a given point.

The triangles are ordered according to

|\
|2\
|--\
|\3|\
|0\|1\
------

Parameters

[in]

global

Coordinates in the reference triangle

Returns

Number of the subtriangle containing global

getSubElement() [2/2]

template<class D >

static void Dune::RefinedSimplexLocalBasis< D, 2 >::getSubElement ( const FieldVector< D, 2 > &  global, int &  subElement, FieldVector< D, 2 > &  local  )

inlinestaticprotected

Get local coordinates in the subtriangle.

Parameters

[in]	global	Coordinates in the reference triangle
[out]	subElement	Number of the subtriangle containing global
[out]	local	The local coordinates in the subtriangle
