TETRAHEDRON_KEAST_RULE\ Quadrature Rules for a Tetrahedron {#tetrahedron_keast_rule-quadrature-rules-for-a-tetrahedron align=”center”} ==================================
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
