virtual const char * | getName () const override |
Returns cubature name. | |
![]() | |
virtual void | getCubature (PointViewType cubPoints, weightViewType cubWeights) const override |
Returns cubature points and weights (return arrays must be pre-sized/pre-allocated). | |
virtual ordinal_type | getNumPoints () const override |
Returns the number of cubature points. | |
virtual ordinal_type | getDimension () const override |
Returns dimension of integration domain. | |
virtual const char * | getName () const override |
Returns cubature name. | |
virtual ordinal_type | getAccuracy () const override |
Returns max. degree of polynomials that are integrated exactly. The return vector has size 1. | |

![]() | |
virtual TensorPointDataType | allocateCubaturePoints () const |
Returns a points container appropriate for passing to getCubature(). | |
virtual TensorWeightDataType | allocateCubatureWeights () const |
Returns a weight container appropriate for passing to getCubature(). | |
virtual void | getCubature (PointViewType, weightViewType) const |
Returns cubature points and weights (return arrays must be pre-sized/pre-allocated). | |
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(). | |
virtual ordinal_type | getNumPoints () const |
Returns the number of cubature points. | |
virtual ordinal_type | getDimension () const |
Returns dimension of the integration domain. | |
virtual ordinal_type | getAccuracy () const |
Returns dimension of the integration domain. | |
virtual const char * | getName () const |
Returns cubature name. | |

Utilizes cubature (integration) rules contained in the library Polylib (Spencer Sherwin, Aeronautics, Imperial College London) within Intrepid.
They are based on zeros of Jacobi polynomials, e.g. Legendre (alpha=beta=0, default), Chebyshev (alpha=beta=-0.5), etc. They are given on the interval [-1,1] and are optimal with respect to the following requirements, yielding 4 subclasses:
