Detailed Description
template<typename ExecSpaceType = void, typename pointValueType = double, typename weightValueType = double>
class Intrepid2::CubatureDirect< ExecSpaceType, pointValueType, weightValueType >
Defines direct cubature (integration) rules in Intrepid.
Cubature template (rule) consists of cubature points and cubature weights. Intrepid provides a small collection of frequently used cubature rule templates for FEM reconstructions on simplices (edge, tri, tet) and pyramid cells.
For quad, hex, and triprism rules, see tensor-product rules defined in the class CubatureTensor, and its derived classes.
Cubature rules for simplices and the pyramid are stored in the cubature_data_ array.
All templates are defined on a reference cell and can be mapped to physical space cells by the methods available in the MultiCell class.
