Detailed Description

interface a cachable quadrature has to implement

Member Function Documentation

size_t Dune::Fem::CachingInterface::cachingPoint ( const size_t quadraturePoint ) const

inline

map quadrature points to caching points

For codim-1 entites, the mapping consists of two stages:

Consider the twist to get the quadrature point number on the face of the (codim-0) reference element,
Map the twisted quadrature point number to the caching point number.

Parameters

[in] quadraturePoint number of quadrature point to map to a caching point

References DUNE_THROW.

size_t Dune::Fem::CachingInterface::interpolationPoint ( const size_t quadraturePoint ) const

inline

map quadrature points to interpolation points

Parameters

[in] quadraturePoint number of quadrature point to map to an interpolation point

References DUNE_THROW.

bool Dune::Fem::CachingInterface::isInterpolationQuadrature ( const size_t numShapeFunctions ) const

inline

check if quadrature is interpolation quadrature

Parameters

[in] numShapeFunctions number of shapeFunctions that has to match number of quadrature points or number of internal interpolation points

References DUNE_THROW.
