◆ BwdTrans()

void Nektar::StdRegions::StdExpansion::BwdTrans	(	const Array< OneD, const NekDouble > &	inarray,

	)

inline

This function performs the Backward transformation from coefficient space to physical space.

This function is a wrapper around the virtual function v_BwdTrans()

Based on the expansion coefficients, this function evaluates the expansion at the quadrature points. This is equivalent to the operation

\[ u(\xi_{1i}) = \sum_{p=0}^{P-1} \hat{u}_p \phi_p(\xi_{1i}) \]

which can be evaluated as \( {\bf u} = {\bf B}^T {\bf \hat{u}} \) with \({\bf B}[i][j] = \phi_i(\xi_{j})\)

This function requires that the coefficient array \(\mathbf{\hat{u}}\) provided as inarray.

The resulting array \(\mathbf{u}[m]=u(\mathbf{\xi}_m)\) containing the expansion evaluated at the quadrature points, is stored in the outarray.

Parameters

inarray	contains the values of the expansion coefficients (input of the function)
outarray	contains the values of the expansion evaluated at the quadrature points (output of the function)

◆ FwdTrans()

void Nektar::StdRegions::StdExpansion::FwdTrans	(	const Array< OneD, const NekDouble > &	inarray,

	)

inline

This function performs the Forward transformation from physical space to coefficient space.

This function is a wrapper around the virtual function v_FwdTrans()

Given a function evaluated at the quadrature points, this function calculates the expansion coefficients such that the resulting expansion approximates the original function.

The calculation of the expansion coefficients is done using a Galerkin projection. This is equivalent to the operation:

\[ \mathbf{\hat{u}} = \mathbf{M}^{-1} \mathbf{I}\]

where

\(\mathbf{M}[p][q]= \int\phi_p(\mathbf{\xi})\phi_q( \mathbf{\xi}) d\mathbf{\xi}\) is the Mass matrix
\(\mathbf{I}[p] = \int\phi_p(\mathbf{\xi}) u(\mathbf{\xi}) d\mathbf{\xi}\)

This function takes the array inarray as the values of the function evaluated at the quadrature points (i.e. \(\mathbf{u}\)), and stores the resulting coefficients \(\mathbf{\hat{u}}\) in the outarray

Parameters

inarray	array of the function discretely evaluated at the quadrature points
outarray	array of the function coefficieints

◆ Integral()

NekDouble Nektar::StdRegions::StdExpansion::Integral ( const Array< OneD, const NekDouble > & inarray )

inline

This function integrates the specified function over the domain.

This function is a wrapper around the virtual function v_Integral()

Based on the values of the function evaluated at the quadrature points (which are stored in inarray), this function calculates the integral of this function over the domain. This is equivalent to the numerical evaluation of the operation

\[ I=\int u(\mathbf{\xi})d \mathbf{\xi}\]

Parameters

inarray values of the function to be integrated evaluated at the quadrature points (i.e. inarray[m]= \(u(\mathbf{\xi}_m)\))

Returns

returns the value of the calculated integral

        Inputs:\n

inarray: definition of function to be returned at quadrature point of expansion.

Outputs:

returns \(\int^1_{-1}\int^1_{-1} u(\xi_1, \xi_2) J[i,j] d \xi_1 d \xi_2 \) where \(inarray[i,j] = u(\xi_{1i},\xi_{2j}) \) and \( J[i,j] \) is the Jacobian evaluated at the quadrature point.

inline

this function calculates the inner product of a given function f with the different modes of the expansion

This function is a wrapper around the virtual function v_IProductWRTBase()

This is equivalent to the numerical evaluation of

\[ I[p] = \int \phi_p(\mathbf{x}) f(\mathbf{x}) d\mathbf{x}\]

\( \begin{array}{rcl} I_{pq} = (\phi_q \phi_q, u) & = & \sum_{i=0}^{nq_0} \sum_{j=0}^{nq_1} \phi_p(\xi_{0,i}) \phi_q(\xi_{1,j}) w^0_i w^1_j u(\xi_{0,i} \xi_{1,j}) J_{i,j}\\ & = & \sum_{i=0}^{nq_0} \phi_p(\xi_{0,i}) \sum_{j=0}^{nq_1} \phi_q(\xi_{1,j}) \tilde{u}_{i,j} J_{i,j} \end{array} \)

where

\( \tilde{u}_{i,j} = w^0_i w^1_j u(\xi_{0,i},\xi_{1,j}) \)

which can be implemented as

\( f_{qi} = \sum_{j=0}^{nq_1} \phi_q(\xi_{1,j}) \tilde{u}_{i,j} = {\bf B_1 U} \) \( I_{pq} = \sum_{i=0}^{nq_0} \phi_p(\xi_{0,i}) f_{qi} = {\bf B_0 F} \)

\param inarray contains the values of the function \a f
evaluated at the quadrature points
\param outarray contains the values of the inner product of \a f
with the different modes, i.e. \f$ outarray[p] = I[p]\f$

inline

This function evaluates the expansion at a single (arbitrary) point of the domain.

This function is a wrapper around the virtual function v_PhysEvaluate()

Based on the value of the expansion at the quadrature points provided in physvals, this function calculates the value of the expansion at an arbitrary single points (with coordinates \( \mathbf{x_c}\) given by the pointer coords). This operation, equivalent to

\[ u(\mathbf{x_c}) = \sum_p \phi_p(\mathbf{x_c}) \hat{u}_p \]

is evaluated using Lagrangian interpolants through the quadrature points:

\[ u(\mathbf{x_c}) = \sum_p h_p(\mathbf{x_c}) u_p\]

Parameters

coords	the coordinates of the single point
physvals	the interpolated field at the quadrature points

Returns: returns the value of the expansion at the single point

◆ PhysEvaluateBasis()

NekDouble Nektar::StdRegions::StdExpansion::PhysEvaluateBasis	(	const Array< OneD, const NekDouble > &	coords,
		int	mode
	)

inline

This function evaluates the basis function mode mode at a point coords of the domain.

This function uses barycentric interpolation with the tensor product separation of the basis function to improve performance.

Parameters

coord	The coordinate inside the standard region.
mode	The mode number to be evaluated.

Returns: The value of the basis function mode at coords.

interpolate from one set of quadrature points available from FromExp to the set of quadrature points in the current expansion. If the points are the same this routine will just copy the data

	)

This function performs an interpolation from the physical space points provided at input into an array of equispaced points which are not the collapsed coordinate. So for a tetrahedron you will only get a tetrahedral number of values.

This is primarily used for output purposes to get a better distribution of points more suitable for most postprocessing
