Detailed Description

template<int dim>
class QGaussPyramid< dim >

Integration rule for pyramid entities. Taken from [33], the integration rules generate (n_points_1d)^3 integration points with all positive weights. The integration rule is the product of two QGauss objects in the first two coordinate directions and a Gauss-Jacobi integration with \(\alpha=2,\beta=0\) in the third direction. This choice of exponents \(\alpha,\beta\) ensures that the decrease of cross-sectional area as \((1-z)^2\) is compensated in the construction of quadrature point locations in \(z\) direction.
