Detailed Description

template<>
class oomph::Gauss< 2, 3 >

2D Gaussian integration class. 3x3 integration points. This integration scheme can integrate up to fifth-order polynomials exactly and is therefore a suitable "full" integration scheme for quadratic (nine-node) elements in which the highest-order polynomial is fourth order.
