Detailed Description

Cell over which can be integrated.

For that a single method exists, which delivers quadrature points, weights and a term from mapping. The method has to be implemented in the derived classes.

Member Function Documentation

quadraturePoint()

virtual bool concepts::IntegrationCell::quadraturePoint ( uint  i, intPoint &  p, intFormType  form = ZERO, bool  localCoord = false  ) const

pure virtual

Delivers a quadrature point.

Quadrature point consists of coordinates (for evaluation of formulas) and intermediate data, consisting of the weight and term coming from mapping.

Returns false, if the number of quadrature points is overstepped.

Parameters

i	number of quadrature point
intPoint	data given back
form	Integration form
localCoord	If true, local coordinates are returned. Else physical coordinates.

Implemented in hp3D::Hexahedron, vectorial::ElementWithCell< F >, hp1D::IntegrableElm, and hp2D::IntegrableQuad.
