Quadrature rules on tetrahedron
 

Does anyone know where I can get quadrature rules on a tetrahedron? I am interested in internal points only, and higher order. There are/were such rules on a site at cs.kuleuven.ac.be called "Encyclopaedia of Cubature Formulas" by R. Cools, but one needs a password, and the link there to secure a password is broken.

Hi Jonas,

The reference book I use to get the points for tetraedron quadratures rules is the following:
The Finite Element Method. Fifth edition. Volume 1: The basis.
O.C.Zienkiewicz, R.L. Taylor.
Chapter 9.10.

It is the reference in Finite Element Method.

Best regards,
