Dune::Fem::TwistStorage< ct, dim > Class Template Reference

Identifies quadrature points on faces with twists For a given quadrature type and a face with a given twist the TwistMapper provides a mapping from the quadrature point number on the twisted face to the quadrature point number on the (untwisted) reference face. (It removes the twist from the quadrature, so to say.) This is needed in unstructured grids when a quadrature point on a reference element's face needs to be transformed to a quadrature point in the reference element itself. More...

Detailed Description

template<class ct, int dim>
class Dune::Fem::TwistStorage< ct, dim >

Identifies quadrature points on faces with twists For a given quadrature type and a face with a given twist the TwistMapper provides a mapping from the quadrature point number on the twisted face to the quadrature point number on the (untwisted) reference face. (It removes the twist from the quadrature, so to say.) This is needed in unstructured grids when a quadrature point on a reference element's face needs to be transformed to a quadrature point in the reference element itself.

The PointMapper objects are filled by the TwistMapperCreator and its subclasses.

Helper class which stores information about twist mapping for a given quadrature id.

Constructor & Destructor Documentation

TwistStorage()

template<class ct , int dim>

Dune::Fem::TwistStorage< ct, dim >::TwistStorage ( int  minTwist, int  maxTwist  )

explicit

Constructor

Parameters

minTwist	Minimal possible twist for the face
maxTwist	Maximal possible twist for the face + 1

Member Function Documentation

getPoints()

template<class ct , int dim>

const TwistStorage< ct, dim >::PointVectorType & Dune::Fem::TwistStorage< ct, dim >::getPoints

Access to the points for all twists (in the case of symmetric quadratures, the points are identical with the quadrature points).
