Detailed Description

template<unsigned DIM>
class QuadraturePointsGroup< DIM >

A simple class which takes in a mesh and a quadrature rule, and collects all the quadrature points in physical space (rather than in natural element coordinates) together in one data structure, for access.

In a distributed mesh, a set of quad points can still be accessed for a given element but then any missing data is marked with DOUBLE_UNSET

Constructor & Destructor Documentation

template<unsigned DIM>
QuadraturePointsGroup< DIM >::QuadraturePointsGroup ( AbstractTetrahedralMesh< DIM, DIM > &  rMesh,
GaussianQuadratureRule< DIM > &  rQuadRule 
)

Constructor takes in a mesh and a rule and computes and stores all the quad points in physical space.

Parameters
rMesh
rQuadRule
