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
DType 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]globalCoordinates 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]globalCoordinates in the reference triangle
[out]subElementNumber of the subtriangle containing global
[out]localThe local coordinates in the subtriangle
