Header file for the Intrepid2::Cubature class.
Defines direct cubature (integration) rules in Intrepid.
void getCubatureFromData(Kokkos::DynRankView< cubPointValueType, cubPointProperties... > cubPoints, Kokkos::DynRankView< cubWeightValueType, cubWeightProperties... > cubWeights, const CubatureData cubData) const
Returns cubature points and weights.
virtual ordinal_type getAccuracy() const override
Returns max. degree of polynomials that are integrated exactly. The return vector has size 1.
ordinal_type dimension_
Dimension of integration domain.
CubatureData cubatureData_
Cubature data on device.
virtual void getCubature(PointViewType cubPoints, weightViewType cubWeights) const override
Returns cubature points and weights (return arrays must be pre-sized/pre-allocated).
virtual const char * getName() const override
Returns cubature name.
ordinal_type degree_
The degree of polynomials that are integrated exactly by this cubature rule.
virtual ordinal_type getDimension() const override
Returns dimension of integration domain.
virtual ordinal_type getNumPoints() const override
Returns the number of cubature points.
Defines the base class for cubature (integration) rules in Intrepid.
static constexpr ordinal_type MaxIntegrationPoints
The maximum number of integration points for direct cubature rules.
static constexpr ordinal_type MaxDimension
The maximum ambient space dimension.
Cubature data is defined on the host space and is static.
weightValueType weights_[Parameters::MaxIntegrationPoints]
Array with the associated cubature weights.
ordinal_type numPoints_
Number of cubature points stored in the template.
pointValueType points_[Parameters::MaxIntegrationPoints][Parameters::MaxDimension]
Array with the (X,Y,Z) coordinates of the cubature points.
Cubature data is defined on exec space and deep-copied when an object is created.
Kokkos::DynRankView< pointValueType, DeviceType > points_
Array with the (X,Y,Z) coordinates of the cubature points.
ordinal_type numPoints_
Number of cubature points stored in the template.
Kokkos::DynRankView< weightValueType, DeviceType > weights_
Array with the associated cubature weights.
