| Abstract: | We present a program for computing symmetric quadrature rules on triangles and tetrahedra.A set of rules are obtained by using this program.Quadrature rules up to order 21 on triangles and up to order 14 on tetrahedra have been obtained which are useful for use in finite element computations.All rules presented here have positive weights with points lying within the integration domain. |
