Detailed Description

template<class Scalar, class ArrayScalar>
class Intrepid::Basis_HGRAD_HEX_Cn_FEM< Scalar, ArrayScalar >

Implementation of the default H(grad)-compatible FEM basis of degree 2 on Hexahedron cell.

Implements Lagrangian basis of degree n on the reference Hexahedron cell. The basis has cardinality (n+1)^3 and spans a COMPLETE polynomial space. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined lexicographically on an array of input points.

template<class Scalar , class ArrayScalar >

void Intrepid::Basis_HGRAD_HEX_Cn_FEM< Scalar, ArrayScalar >::getValues	(	ArrayScalar &	outputValues,
		const ArrayScalar &	inputPoints,
		const EOperator	operatorType
	)		const [virtual]

Evaluation of a FEM basis on a reference Hexahedron cell.

Returns values of operatorType acting on FEM basis functions for a set of points in the reference Hexahedron cell. For rank and dimensions of I/O array arguments see Section MD array template arguments for basis methods.

Parameters:

outputValues	[out] - rank-2 or 3 array with the computed basis values
inputPoints	[in] - rank-2 array with dimensions (P,D) containing reference points
operatorType	[in] - operator applied to basis functions

Implements Intrepid::Basis< Scalar, ArrayScalar >.
