Detailed Description

template<typename DeviceType = void, typename pointValueType = double, typename weightValueType = double>
class Intrepid2::Cubature< DeviceType, pointValueType, weightValueType >

Defines the base class for 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 the pyramid cell, defined in the derived classes of CubatureDirect.

For quad, hex, and triprism cells cubature templates are tensor products of CubatureDirect templates. The tensor-product cubatures are defined in the derived class CubatureTensor.

virtual void Intrepid2::Cubature< DeviceType, pointValueType, weightValueType >::getCubature	(	PointViewType	,
		weightViewType	,
		PointViewType
	)		const

inlinevirtual

Returns cubature points and weights on physical cells (return arrays must be pre-sized/pre-allocated).

Parameters

cubPoints	[out] - Array containing the cubature points.
cubWeights	[out] - Array of corresponding cubature weights.
cellVertices	[in] - Array containing the cell vertices.

virtual void Intrepid2::Cubature< DeviceType, pointValueType, weightValueType >::getCubature	(	const TensorPointDataType &	tensorCubPoints,
		const TensorWeightDataType &	tensorCubWeights
	)		const

inlinevirtual

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().

Parameters

cubPoints	[out] - TensorPoints structure containing the cubature points.
cubWeights	[out] - TensorData structure containing cubature weights.
