Abstract :

This paper presents a technique to evaluate the integrals over the triangular surfaces using readily available Gaussian quadrature for the square domain integrals. As the technique suitably can employ higher order Gaussian quadrature and have higher degree of accuracy of the integrals is possible to achieve without resorting to inefficient quadrature for triangles
