oomph::TGauss< 2, 4 > Class Reference

2D Gaussian integration class for cubic triangles. Thirteen integration points. This integration scheme can integrate up to seventh-order polynomials exactly and is therefore a suitable "full" integration scheme for cubic (ten-node) elements in which the highest-order polynomial is sixth order.
