Detailed Description

template<typename BasisFunctionType>
class Bempp::ScalarSpace< BasisFunctionType >

Base class for spaces of scalar-valued functions.

Member Function Documentation

template<typename BasisFunctionType >

const ScalarSpace< BasisFunctionType >::CollectionOfShapesetTransformations & Bempp::ScalarSpace< BasisFunctionType >::basisFunctionValue ( ) const

virtual

Transformation mapping shape functions to basis functions.

This function returns a CollectionOfShapesetTransformations object consisting of a single transformation that maps values of shape functions defined on a reference element to those of basis functions defined on a particular element of the grid.

This transformation is the identity for spaces of scalar-valued functions, but may be more complicated for spaces of vector-valued functions, e.g. $H(\mathrm{curl})$ .

Reimplemented from Bempp::Space< BasisFunctionType >.

template<typename BasisFunctionType >

void Bempp::ScalarSpace< BasisFunctionType >::getGlobalDofInterpolationDirections ( arma::Mat< CoordinateType > & directions ) const

virtual

Retrieve the interpolation directions of the global degrees of freedom.

This function fills the 2D array points whose (i, j)th element contains the ith component of the vector $d_j$ defined in the documentation of getGlobalDofInterpolationPoints().
