TETRAHEDRON_KEAST_RULE is a C++ library which defines ten quadrature rules, of degree of exactness 0 through 8, over the interior of the tetrahedron in 3D.
The ten rules have the following orders and precisions:
Rule | Order | Precision |
---|---|---|
1 | 1 | 1 |
2 | 4 | 2 |
3 | 5 | 3 |
4 | 10 | 3 |
5 | 11 | 4 |
6 | 14 | 4 |
7 | 15 | 5 |
8 | 24 | 6 |
9 | 31 | 7 |
10 | 45 | 8 |
