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.

const SpatialDomains::MeshGraphSharedPtr graph1D,
const std::string &  variable,
const bool  SetUpJustDG = true,
const Collections::ImplementationType  ImpType = Collections::eNoImpType 
)

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
graph1DA mesh, containing information about the domain and the spectral/hp element expansions.
bcsInformation about the enforced boundary conditions.
variableThe session variable associated with the boundary conditions to enforce.
solnTypeType of global system to use.

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
inarrayAn array containing the 1D data from which we wish to extract the edge data.
outarrayThe 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 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
fieldis a NekDouble array which contains the 1D data from which we wish to extract the backward and forward orientated trace/edge arrays.
FwdThe resulting forwards space.
BwdThe resulting backwards space.
