Detailed Description

template<unsigned ELEMENT_DIM>
class GaussianQuadratureRule< ELEMENT_DIM >

This class encapsulates tables of Gaussian quadrature points and the associated weights.

Data is available for 1d, 2d and 3d quadrature over (canonical) triangles, with appropriate numbers of Gauss points. Weights sum to 1 and are non-negative. The values are computed when an object is instantiated.

Constructor & Destructor Documentation

template<unsigned ELEMENT_DIM>

GaussianQuadratureRule< ELEMENT_DIM >::GaussianQuadratureRule

(

unsigned

quadratureOrder

)

The constructor builds the appropriate table for the dimension (given by the template argument) and number of points in each dimension (given as a constructor argument).

An exception is thrown if data is not available for the requested parameters.

Parameters

quadratureOrder

The minimum polynomial order that the rule can integrate exactly
