Detailed Description

This class is the abstraction of a one-dimensional multi-elemental expansions which is merely a collection of local expansions.

This multi-elemental expansion, which does not exhibit any coupling between the expansion on the separate elements, can be formulated as,

$u^{\delta}(x_i)=\sum_{e=1}^{{N_{\mathrm{el}}}} \sum_{n=0}^{N^{e}_m-1}\hat{u}_n^e\phi_n^e(x_i).$

where ${N_{\mathrm{el}}}$ is the number of elements and $N^{e}_m$ is the local elemental number of expansion modes.

Instances of this class may be optionally constructed which use generalised segment expansions (LocalRegions::GenSegExp), rather than the standard segment expansions (LocalRegions::SegExp). LocalRegions::GenSegExp provides additional spatial data including segment normals and is enabled using the UseGenSegExp flag.

This class inherits all its variables and member functions from the base class MultiRegions::ExpList.

		const SpatialDomains::MeshGraphSharedPtr &	graph1D
	)

Construct an ExpList1D from a given graph.

After initialising the data inherited through MultiRegions::ExpList, populate the expansion list from the segments defined in the supplied SpatialDomains::MeshGraph1D. All expansions in the graph are defined using the same LibUtilities::BasisKey which overrides that specified in graph1D.

See also: ExpList1D::ExpList1D(SpatialDomains::MeshGraph1D&, bool) for details.

Deprecated:

This constructor is no longer required since the basis key is now available from the graph.

Parameters

Ba	BasisKey describing quadrature points and number of modes.
graph1D	Domain and expansion definitions.

		const SpatialDomains::MeshGraphSharedPtr &	graph1D,
		const bool	DeclareCoeffPhysArrays = `true`
	)

This constructor sets up a list of local expansions based on an input graph1D.

Given a mesh graph1D, containing information about the domain and the spectral/hp element expansion, this constructor fills the list of local expansions {m_exp} with the proper expansions, calculates the total number of quadrature points $x_i$ and local expansion coefficients $\hat{u}^e_n$ and allocates memory for the arrays m_coeffs and m_phys.

For each element its corresponding LibUtilities::BasisKey is retrieved and this is used to construct either a standard segment (LocalRegions::SegExp) or a generalised segment (LocalRegions::GenSegExp) which is stored in the list m_exp. Finally, ExpList::SetCoeffPhys is called to initialise the data storage areas and set up the offset arrays.

Parameters

graph1D	A mesh, containing information about the domain and the spectral/hp element expansion.
UseGenSegExp	If true, create general segment expansions instead of just normal segment expansions.

		const bool	DeclareCoeffPhysArrays = `true`,

	)

This constructor sets up a list of local expansions based on an input compositeMap.

Given a mesh graph1D, and the spectral/hp element expansion as well as and separate information about a domain, this constructor fills the list of local expansions {m_exp} with the proper expansions, calculates the total number of quadrature points $x_i$ and local expansion coefficients $\hat{u}^e_n$ and allocates memory for the arrays m_coeffs and m_phys.

For each element its corresponding LibUtilities::BasisKey is retrieved and this is used to construct either a standard segment (LocalRegions::SegExp) or a generalised segment (LocalRegions::GenSegExp) which is stored in the list m_exp. Finally, ExpList::SetCoeffPhys is called to initialise the data storage areas and set up the offset arrays.

Parameters

graph1D	A mesh, containing information about the domain and the spectral/hp element expansion.
UseGenSegExp	If true, create general segment expansions instead of just normal segment expansions.

		const bool	DeclareCoeffPhysArrays = `true`,
		const std::string	variable = `"DefaultVar"`
	)

Specialised constructor for Neumann boundary conditions in DisContField2D and ContField2D.

Fills the list of local expansions with the segments from the 2D mesh specified by domain. This CompositeMap contains a list of Composites which define the Neumann boundary.

See also: ExpList1D::ExpList1D(SpatialDomains::MeshGraph1D&, bool) for details.

Parameters

domain	A domain, comprising of one or more composite regions,
graph2D	A mesh, containing information about the domain and the spectral/hp element expansion.
UseGenSegExp	If true, create general segment expansions instead of just normal segment expansions.

void Nektar::MultiRegions::ExpList1D::ParNormalSign ( Array< OneD, NekDouble > & normsign )

Set up the normals on each expansion.

void Nektar::MultiRegions::ExpList1D::PeriodicEval	(	Array< OneD, NekDouble > &	inarray1,
		Array< OneD, NekDouble > &	inarray2,
		NekDouble	h,
		int	nmodes,
		Array< OneD, NekDouble > &	outarray
	)

Evaluates the global spectral/hp expansion at some arbitray set of points.

Given the elemental coefficients $\hat{u}_n^e$ of an expansion, periodically evaluate the spectral/hp expansion $u^{\delta}(\boldsymbol{x})$ at arbitrary points.

Parameters

inarray1	An array of size $N_{\mathrm{eof}}$ containing the local coefficients $\hat{u}_n^e$ .
inarray2	Contains the set of evaluation points.
h	The mesh spacing.
nmodes	The number of polynomial modes for each element (we consider that each element has the same number of polynomial modes).
outarray	Contains the resulting values at the evaluation points

void Nektar::MultiRegions::ExpList1D::SetCoeffPhysOffsets ( void )

private

Definition of the total number of degrees of freedom and quadrature points. Sets up the storage for m_coeff and m_phys.

Each expansion (local element) is processed in turn to determine the number of coefficients and physical data points it contributes to the domain. Three arrays, m_coeff_offset, m_phys_offset and m_offset_elmt_id, are also initialised and updated to store the data offsets of each element in the m_coeffs and m_phys arrays, and the element id that each consecutive block is associated respectively.
