template<class HGRAD_LINE , class HVOL_LINE >
virtual void Intrepid2::Basis_Derived_HDIV_Family2_QUAD< HGRAD_LINE, HVOL_LINE >::getDofCoeffs ( ScalarViewType  dofCoeffs) const
inlineoverridevirtual

Fills in coefficients of degrees of freedom for Lagrangian basis on the reference cell.

Parameters
[out]dofCoeffs- the container into which to place the degrees of freedom.

dofCoeffs have shape (F,D), field dimension matches the cardinality of the basis, and D is the basis dimension.

Degrees of freedom coefficients are such that (dofCoords_(j)) dofCoeffs_(j) = , where are the basis and the Kronecker delta. Note that getDofCoeffs() is supported only for Lagrangian bases.

◆ getValues() [1/5]

template<class HGRAD_LINE , class HVOL_LINE >
virtual void Intrepid2::Basis_TensorBasis< BasisBaseClass >::getValues
inline

Evaluation of a tensor FEM basis on a reference cell; subclasses should override this.

Returns values of operatorType acting on FEM basis functions for a set of points in the reference cell for which the basis is defined.

Parameters
outputValues[out] - variable rank array with the basis values
operatorType[in] - the operator acting on the basis functions
inputPoints1[in] - rank-2 array (P1,D1) with the evaluation points for basis1
inputPoints2[in] - rank-2 array (P2,D2) with the evaluation points for basis2
tensorPoints[in] - whether the points should be interpreted as tensor components of the evaluation points, or in a one-to-one correspondence

Subclasses should override this method; this gives them an opportunity to specify how operatorType should be decomposed into operators on the component bases.

If tensorPoints is true, then the points dimension of outputValues should be (P1*P2). If tensorPoints is false, then P1 should equal P2, and these should match the points dimension of outputValues.

There are three variants of getValues:

  1. The three-argument version defined by Intrepid2::Basis. TensorBasis provides an implementation of this, which calls the five-argument version (this one).
  2. The five-argument version (this method), which provides separate point sets for the component bases, and must be specified by subclasses. Typical implementations call the seven-argument version.
  3. The seven-argument version (below), implemented by TensorBasis, which provides separate point sets and operators for the component bases, as well as an optional weight.

The intent is that subclasses implement this five-argument version; in that implementation, they need to do little else than call the seven-argument version below.

Note that the three-argument implementation handles the OPERATOR_Dn operators directly; that is, subclasses can omit any consideration of OPERATOR_Dn operators in their implementation of the five-argument version.

◆ getValues() [2/5]

template<class HGRAD_LINE , class HVOL_LINE >
void Intrepid2::Basis_TensorBasis< BasisBaseClass >::getValues
inlineoverride

Evaluation of a FEM basis on a reference cell.

Returns values of operatorType acting on FEM basis functions for a set of points in the reference cell for which the basis is defined.

Parameters
outputValues[out] - variable rank array with the basis values
inputPoints[in] - rank-2 array (P,D) with the evaluation points
operatorType[in] - the operator acting on the basis functions
Remarks
For rank and dimension specifications of the output array see Section MD array template arguments for basis methods. Dimensions of ArrayScalar arguments are checked at runtime if HAVE_INTREPID2_DEBUG is defined.
A FEM basis spans a COMPLETE or INCOMPLETE polynomial space on the reference cell which is a smooth function space. Thus, all operator types that are meaningful for the approximated function space are admissible. When the order of the operator exceeds the degree of the basis, the output array is filled with the appropriate number of zeros.

◆ getValues() [3/5]

template<class HGRAD_LINE , class HVOL_LINE >
virtual void Intrepid2::Basis_TensorBasis< BasisBaseClass >::getValues
inlineoverride

Evaluation of a FEM basis on a reference cell, using point and output value containers that allow preservation of tensor-product structure.

Returns values of operatorType acting on FEM basis functions for a set of points in the reference cell for which the basis is defined.

Parameters
outputValues[out] - variable rank array with the basis values. Should be allocated using Basis::allocateBasisValues().
inputPoints[in] - rank-2 array (P,D) with the evaluation points. This should be allocated using Cubature::allocateCubaturePoints() and filled using Cubature::getCubature().
operatorType[in] - the operator acting on the basis function

This is the preferred getValues() method for TensorBasis and DirectSumBasis and their subclasses. It allows a reduced memory footprint and optimized integration, etc.

◆ getValues() [4/5]

template<class HGRAD_LINE , class HVOL_LINE >
void Intrepid2::Basis_TensorBasis< BasisBaseClass >::getValues
inline

Evaluation of a tensor FEM basis on a reference cell.

Returns values of operatorType acting on FEM basis functions for a set of points in the reference cell for which the basis is defined.

Parameters
outputValues[out] - variable rank array with the basis values
inputPoints1[in] - rank-2 array (P1,D1) with the evaluation points for basis1
operatorType1[in] - the operator acting on basis1
inputPoints2[in] - rank-2 array (P2,D2) with the evaluation points for basis2
operatorType2[in] - the operator acting on basis2
tensorPoints[in] - whether the points should be interpreted as tensor components of the evaluation points, or in a one-to-one correspondence
weight[in] - optional weight (typically 1.0 or -1.0)

If tensorPoints is true, then the points dimension of outputValues should be (P1*P2). If tensorPoints is false, then P1 should equal P2, and these should match the points dimension of outputValues.

There are three variants of getValues:

  1. The three-argument version defined by Intrepid2::Basis. TensorBasis provides an implementation of this, which calls the five-argument version (this one).
  2. The five-argument version (above), which provides separate point sets for the component bases, and must be specified by subclasses. Typical implementations call the seven-argument version.
  3. The seven-argument version (this method), implemented by TensorBasis, which provides separate point sets and operators for the component bases, as well as an optional weight.

Subclasses should override the five-argument version above; in their implementation, they need to do little else than call this seven-argument version.

multi-component getValues() method (required/called by TensorBasis)

Parameters
[out]outputValues- the view into which to place the output values
[in]operatorType- the operator on the basis
[in]inputPoints1- input points in the x dimension
[in]inputPoints2- input points in the y dimension
[in]tensorPoints- if true, inputPoints1 and inputPoints2 should be understood as tensorial components of the points in outputValues (i.e., the evaluation points are the tensor product of inputPoints1 and inputPoints2). If false, inputPoints1 and inputPoints2 should correspond elementwise to the evaluation points.
