Member Function Documentation

void Nektar::MultiRegions::DisContField3D::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 .

This function evaluates the boundary conditions at a certain time-level.

Based on the boundary condition $g(\boldsymbol{x},t)$ evaluated at a given time-level t, this function transforms the boundary conditions onto the coefficients of the (one-dimensional) boundary expansion. Depending on the type of boundary conditions, these expansion coefficients are calculated in different ways:

Dirichlet boundary conditions
In order to ensure global continuity of the spectral/hp approximation, the Dirichlet boundary conditions are projected onto the boundary expansion by means of a modified continuous Galerkin projection. This projection can be viewed as a collocation projection at the vertices, followed by an projection on the interior modes of the edges. The resulting coefficients $\boldsymbol{\hat{u}}^{\mathcal{D}}$ will be stored for the boundary expansion.
Neumann boundary conditions In the discrete Galerkin formulation of the problem to be solved, the Neumann boundary conditions appear as the set of surface integrals:
$\boldsymbol{\hat{g}}=\int_{\Gamma} \phi^e_n(\boldsymbol{x})g(\boldsymbol{x})d(\boldsymbol{x})\quad \forall n$
As a result, it are the coefficients $\boldsymbol{\hat{g}}$ that will be stored in the boundary expansion

Parameters

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

void Nektar::MultiRegions::DisContField3D::v_GetFwdBwdTracePhys	(	Array< OneD, NekDouble > &	Fwd,
		Array< OneD, NekDouble > &	Bwd
	)

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 face of each element and its corresponding face in the trace space using the mapping m_traceMap. The element can either be left-adjacent or right-adjacent to this trace face (see Expansion2D::GetLeftAdjacentElementExp). Boundary faces are always left-adjacent since left-adjacency is populated first.

If the element is left-adjacent we extract the face 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 3D data from which we wish to extract the backward and forward orientated trace/face arrays.

Returns: Updates a NekDouble array Fwd and Bwd

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

Returns: std map containing the robin boundary condition info using a key of the element id

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

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::ExpList2D. Every entry corresponds to the two-dimensional spectral/hp expansion on a single boundary region. The values of the boundary conditions are stored as the coefficients of the two-dimensional expansion.
