Member Function Documentation

void Nektar::MultiRegions::DisContField2D::EvaluateHDGPostProcessing ( Array< OneD, NekDouble > & outarray )

Evaluate HDG post-processing to increase polynomial order of solution.

This function takes the solution (assumed to be one order lower) in physical space, and postprocesses at the current polynomial order by solving the system:

$\begin{aligned} (\nabla w, \nabla u^*) &= (\nabla w, u), \\ \langle \nabla u^*, 1 \rangle &= \langle \nabla u, 1 \rangle \end{aligned}$

where $ u $ corresponds with the current solution as stored inside m_coeffs.

Parameters

outarray The resulting field .

void Nektar::MultiRegions::DisContField2D::FindPeriodicEdges	(	const SpatialDomains::BoundaryConditions &	bcs,
		const std::string &	variable
	)

protected

Determine the periodic edges and vertices for the given graph.

Note that much of this routine is the same as the three-dimensional version, which therefore has much better documentation.

Parameters

bcs	Information about the boundary conditions.
variable	Specifies the field.

void Nektar::MultiRegions::DisContField2D::GenerateBoundaryConditionExpansion	(	const SpatialDomains::MeshGraphSharedPtr &	graph2D,
		const SpatialDomains::BoundaryConditions &	bcs,
		const std::string &	variable,
		const bool	DeclareCoeffPhysArrays = `true`
	)

protected

This function discretises the boundary conditions by setting up a list of one-dimensional boundary expansions.

According to their boundary region, the separate segmental boundary expansions are bundled together in an object of the class MultiRegions::ExpList1D.

Parameters

graph2D	A mesh, containing information about the domain and the spectral/hp element expansion.
bcs	An entity containing information about the boundaries and boundary conditions.
variable	An optional parameter to indicate for which variable the boundary conditions should be discretised.

NekDouble Nektar::MultiRegions::DisContField2D::L2_DGDeriv	(	const int	dir,

Calculate the $ L^2 $ error of the $Q_{\rm dir}$ derivative using the consistent DG evaluation of $Q_{\rm dir}$ .

The solution provided is of the primative variation at the quadrature points and the derivative is compared to the discrete derivative at these points, which is likely to be undesirable unless using a much higher number of quadrature points than the polynomial order used to evaluate $Q_{\rm dir}$ .

Add trace contributions into elemental coefficient spaces.

Given some quantity $\vec{q}$ , calculate the elemental integral

$\int_{\Omega^e} \vec{q}, \mathrm{d}S$

and adds this to the coefficient space provided by outarray. The value of q is determined from the routine IsLeftAdjacentEdge() which if true we use Fwd else we use Bwd

See also: Expansion2D::AddEdgeNormBoundaryInt

Parameters

Fwd	The trace quantities associated with left (fwd) adjancent elmt.
Bwd	The trace quantities associated with right (bwd) adjacent elet.
outarray	Resulting 2D coefficient space.

Evaluates the boundary condition expansions, bndCondExpansions, given the information provided by bndConditions.

Parameters

time	The time at which the boundary conditions should be evaluated.
bndCondExpansions	List of boundary conditions.
bndConditions	Information about the boundary conditions.

This will only be undertaken for time dependent boundary conditions unless time == 0.0 which is the case when the method is called from the constructor.

void Nektar::MultiRegions::DisContField2D::v_ExtractTracePhys	(	const Array< OneD, const NekDouble > &	inarray,

	)

protectedvirtual

This method extracts the trace (edges in 2D) from the field inarray and puts the values in outarray.

It assumes the field is C0 continuous so that it can overwrite the edge data when visited by the two adjacent elements.

Parameters

inarray	An array containing the 2D data from which we wish to extract the edge data.
outarray	The resulting edge information.

	)

protectedvirtual

This method extracts the "forward" and "backward" trace data from the array field and puts the data into output vectors Fwd and Bwd.

We first define the convention which defines "forwards" and "backwards". First an association is made between the edge of each element and its corresponding edge in the trace space using the mapping m_traceMap. The element can either be left-adjacent or right-adjacent to this trace edge (see Expansion1D::GetLeftAdjacentElementExp). Boundary edges are always left-adjacent since left-adjacency is populated first.

If the element is left-adjacent we extract the edge trace data from field into the forward trace space Fwd; otherwise, we place it in the backwards trace space Bwd. In this way, we form a unique set of trace normals since these are always extracted from left-adjacent elements.

Parameters

field	is a NekDouble array which contains the 2D data from which we wish to extract the backward and forward orientated trace/edge arrays.
Fwd	The resulting forwards space.
Bwd	The resulting backwards space.

Search through the edge expansions and identify which ones have Robin/Mixed type boundary conditions.

If a Robin boundary is found then store the edge ID of the boundary condition and the array of points of the physical space boundary condition which are hold the boundary condition primitive variable coefficient at the quatrature points

Returns: A map containing the Robin boundary condition information using a key of the element ID.

Array<OneD,MultiRegions::ExpListSharedPtr> Nektar::MultiRegions::DisContField2D::m_bndCondExpansions

protected

An object which contains the discretised boundary conditions.

It is an array of size equal to the number of boundary regions and consists of entries of the type MultiRegions::ExpList1D. Every entry corresponds to the one-dimensional spectral/hp expansion on a single boundary region. The values of the boundary conditions are stored as the coefficients of the one-dimensional expansion.
