Detailed Description
This class is the abstraction of a global continuous two- dimensional spectral/hp element expansion which approximates the solution of a set of partial differential equations.
The class ContField is able to incorporate the boundary conditions imposed to the problem to be solved. Therefore, the class is equipped with three additional data members:
- m_bndCondExpansions
- #m_bndTypes
- #m_bndCondEquations
The first data structure, m_bndCondExpansions, contains the one-dimensional spectral/hp expansion on the boundary, #m_bndTypes stores information about the type of boundary condition on the different parts of the boundary while #m_bndCondEquations holds the equation of the imposed boundary conditions.
Furthermore, in case of Dirichlet boundary conditions, this class is capable of lifting a known solution satisfying these boundary conditions. If we denote the unknown solution by \(u^{\mathcal{H}}(\boldsymbol{x})\) and the known Dirichlet boundary conditions by \(u^{\mathcal{D}}(\boldsymbol{x})\), the expansion then can be decomposed as
\[ u^{\delta}(\boldsymbol{x}_i)=u^{\mathcal{D}}(\boldsymbol{x}_i)+ u^{\mathcal{H}}(\boldsymbol{x}_i)=\sum_{n=0}^{N^{\mathcal{D}}-1} \hat{u}_n^{\mathcal{D}}\Phi_n(\boldsymbol{x}_i)+ \sum_{n={N^{\mathcal{D}}}}^{N_{\mathrm{dof}}-1} \hat{u}_n^{\mathcal{H}} \Phi_n(\boldsymbol{x}_i).\]
This lifting is accomplished by ordering the known global degrees of freedom, prescribed by the Dirichlet boundary conditions, first in the global array \(\boldsymbol{\hat{u}}\), that is,
\[\boldsymbol{\hat{u}}=\left[ \begin{array}{c} \boldsymbol{\hat{u}}^{\mathcal{D}}\\ \boldsymbol{\hat{u}}^{\mathcal{H}} \end{array} \right].\]
Such kind of expansions are also referred to as continuous fields. This class should be used when solving 2D problems using a standard Galerkin approach.

||
| ) |
Solves the linear system specified by the key key.
Given a linear system specified by the key key,
\[\boldsymbol{M}\boldsymbol{\hat{u}}_g=\boldsymbol{\hat{f}},\]
this function solves this linear system taking into account the boundary conditions specified in the data member m_bndCondExpansions. Therefore, it adds an array \(\boldsymbol{\hat{g}}\) which represents the non-zero surface integral resulting from the weak boundary conditions (e.g. Neumann boundary conditions) to the right hand side, that is,
\[\boldsymbol{M}\boldsymbol{\hat{u}}_g=\boldsymbol{\hat{f}}+ \boldsymbol{\hat{g}}.\]
Furthermore, it lifts the known degrees of freedom which are prescribed by the Dirichlet boundary conditions. As these known coefficients \(\boldsymbol{\hat{u}}^{\mathcal{D}}\) are numbered first in the global coefficient array \(\boldsymbol{\hat{u}}_g\), the linear system can be decomposed as,
\[\left[\begin{array}{cc} \boldsymbol{M}^{\mathcal{DD}}&\boldsymbol{M}^{\mathcal{DH}}\\ \boldsymbol{M}^{\mathcal{HD}}&\boldsymbol{M}^{\mathcal{HH}} \end{array}\right] \left[\begin{array}{c} \boldsymbol{\hat{u}}^{\mathcal{D}}\\ \boldsymbol{\hat{u}}^{\mathcal{H}} \end{array}\right]= \left[\begin{array}{c} \boldsymbol{\hat{f}}^{\mathcal{D}}\\ \boldsymbol{\hat{f}}^{\mathcal{H}} \end{array}\right]+ \left[\begin{array}{c} \boldsymbol{\hat{g}}^{\mathcal{D}}\\ \boldsymbol{\hat{g}}^{\mathcal{H}} \end{array}\right] \]
which will then be solved for the unknown coefficients \(\boldsymbol{\hat{u}}^{\mathcal{H}}\) as,
\[ \boldsymbol{M}^{\mathcal{HH}}\boldsymbol{\hat{u}}^{\mathcal{H}}= \boldsymbol{\hat{f}}^{\mathcal{H}}+ \boldsymbol{\hat{g}}^{\mathcal{H}}- \boldsymbol{M}^{\mathcal{HD}}\boldsymbol{\hat{u}}^{\mathcal{D}}\]
- Parameters

Solves the two-dimensional Laplace equation, subject to the boundary conditions specified.
Consider the two dimensional Laplace equation,
\[\nabla\cdot\left(\boldsymbol{\sigma}\nabla u(\boldsymbol{x})\right) = f(\boldsymbol{x}),\]
supplemented with appropriate boundary conditions (which are contained in the data member m_bndCondExpansions). In the equation above \(\boldsymbol{\sigma}\) is the (symmetric positive definite) diffusion tensor:
\[ \sigma = \left[ \begin{array}{cc} \sigma_{00}(\boldsymbol{x},t) & \sigma_{01}(\boldsymbol{x},t) \\ \sigma_{01}(\boldsymbol{x},t) & \sigma_{11}(\boldsymbol{x},t) \end{array} \right]. \]
Applying a \(C^0\) continuous Galerkin discretisation, this equation leads to the following linear system:
\[\boldsymbol{L} \boldsymbol{\hat{u}}_g=\boldsymbol{\hat{f}}\]
where \(\boldsymbol{L}\) is the Laplacian matrix. This function solves the system above for the global coefficients \(\boldsymbol{\hat{u}}\) by a call to the function GlobalSolve.
The values of the function \(f(\boldsymbol{x})\) evaluated at the quadrature points \(\boldsymbol{x}_i\) should be contained in the variable #inarray
- Parameters
-
inarray An Array<OneD, NekDouble> containing the discrete evaluation of the forcing function \(f(\boldsymbol{x})\) at the quadrature points. outarray An Array<OneD, NekDouble> containing the coefficients of the solution variablecoeffs The (optional) parameter containing the coefficients evaluated at the quadrature points. It is an Array of (three) arrays which stores the laplacian coefficients in the following way \[\mathrm{variablecoeffs} = \left[ \begin{array}{c} \left[\sigma_{00}(\boldsymbol{x_i},t)\right]_i \\ \left[\sigma_{01}(\boldsymbol{x_i},t)\right]_i \\ \left[\sigma_{11}(\boldsymbol{x_i},t)\right]_i \end{array}\right] \]
If this argument is not passed to the function, the following equation will be solved:\[\nabla^2u(\boldsymbol{x}) = f(\boldsymbol{x}),\]
time The time-level at which the coefficients are evaluated

Solves the two-dimensional Helmholtz equation, subject to the boundary conditions specified.
Consider the two dimensional Helmholtz equation,
\[\nabla^2u(\boldsymbol{x})-\lambda u(\boldsymbol{x}) = f(\boldsymbol{x}),\]
supplemented with appropriate boundary conditions (which are contained in the data member m_bndCondExpansions). Applying a \(C^0\) continuous Galerkin discretisation, this equation leads to the following linear system:
\[\left(\boldsymbol{L}+\lambda\boldsymbol{M}\right) \boldsymbol{\hat{u}}_g=\boldsymbol{\hat{f}}\]
where \(\boldsymbol{L}\) and \(\boldsymbol{M}\) are the Laplacian and mass matrix respectively. This function solves the system above for the global coefficients \(\boldsymbol{\hat{u}}\) by a call to the function GlobalSolve.
- Parameters
-
inarray An Array<OneD, NekDouble> , containing the discrete evaluation of the forcing function \(f(\boldsymbol{x})\) at the quadrature points factors The parameter \(\lambda\) of the Helmholtz equation is specified through the factors map

overrideprotectedvirtual |
Gathers the global coefficients \(\boldsymbol{\hat{u}}_g\) from the local coefficients \(\boldsymbol{\hat{u}}_l\).
This operation is evaluated as:
\begin{tabbing} \hspace{1cm} \= Do \= $e=$ $1, N_{\mathrm{el}}$ \\ \> \> Do \= $i=$ $0,N_m^e-1$ \\ \> \> \> $\boldsymbol{\hat{u}}_g[\mbox{map}[e][i]] = \mbox{sign}[e][i] \cdot \boldsymbol{\hat{u}}^{e}[i]$\\ \> \> continue\\ \> continue \end{tabbing}
where map \([e][i]\) is the mapping array and sign \([e][i]\) is an array of similar dimensions ensuring the correct modal connectivity between the different elements (both these arrays are contained in the data member m_locToGloMap). This operation is equivalent to the gather operation \(\boldsymbol{\hat{u}}_g=\mathcal{A}^{-1}\boldsymbol{\hat{u}}_l\), where \(\mathcal{A}\) is the \(N_{\mathrm{eof}}\times N_{\mathrm{dof}}\) permutation matrix.
