Detailed Description

This class is the abstraction of a global discontinuous two- dimensional spectral/hp element expansion which approximates the solution of a set of partial differential equations.

This class augments the list of local expansions inherited from ExpList1D with boundary conditions. Inter-element boundaries are handled using an discontinuous Galerkin scheme.

Constructor & Destructor Documentation

Nektar::MultiRegions::DisContField1D::DisContField1D ( )

Default constructor.

Constructs an empty expansion list with no boundary conditions.

		const SpatialDomains::MeshGraphSharedPtr &	graph1D,
		const std::string &	variable,
		const bool	SetUpJustDG = `true`
	)

Constructs a 1D discontinuous field based on a mesh and boundary conditions.

An expansion list for the boundary expansions is generated first for the field. These are subsequently evaluated for time zero. The trace map is then constructed.

Parameters

graph1D	A mesh, containing information about the domain and the spectral/hp element expansions.
bcs	Information about the enforced boundary conditions.
variable	The session variable associated with the boundary conditions to enforce.
solnType	Type of global system to use.

bndCondExpansions	List of boundary expansions.
bndConditions	Information about the boundary conditions.

protectedvirtual

This method extracts the trace (verts in 1D) 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 1D data from which we wish to extract the edge data.
outarray	The resulting edge information.

This will not work for non-boundary expansions

	)

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 vertex of each element and its corresponding vertex in the trace space using the mapping m_traceMap. The element can either be left-adjacent or right-adjacent to this trace edge (see Expansion0D::GetLeftAdjacentElementExp). Boundary edges are never left-adjacent since elemental left-adjacency is populated first.

If the element is left-adjacent we extract the vertex 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 1D 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 find a Robin boundary 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

There is a next member to allow for more than one Robin boundary condition per element

Array<OneD,MultiRegions::ExpListSharedPtr> Nektar::MultiRegions::DisContField1D::m_bndCondExpansions

protected

Discretised boundary conditions.

It is an array of size equal to the number of boundary points and consists of entries of the type LocalRegions::PointExp. Every entry corresponds to a point on a single boundary region.
