virtual void | getCubature (PointViewType, weightViewType, PointViewType) const |
Returns cubature points and weights on physical cells (return arrays must be pre-sized/pre-allocated). | |
virtual void | getCubature (const TensorPointDataType &tensorCubPoints, const TensorWeightDataType &tensorCubWeights) const |
Returns tensor cubature points and weights. For non-tensor cubatures, the tensor structures are trivial, thin wrappers around the data returned by getCubature(). The provided containers should be pre-allocated through calls to allocateCubaturePoints() and allocateCubatureWeights(). | |

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.
