Apply linear extrapolation boundary condition to a
group of grid functions given by their indices.

extrapolation boundary condition.

\begin{abstract}
Provides a simple linear extrapolation boundary condition, to serve as

\end{abstract}
\section{Introduction}
This thorn provides a linear extrapolation boundary condition in three
dimensions. It is intended as an example for writing physical
boundary conditions. (See the ThornGuide for
\texttt{CactusBase/Boundary} for details on Cactus boundary
conditions.) It is registered under the name \texttt{LinearExtrap}.
The code which actually implements the boundary condition is written
in fixed form Fortran 90, in the file \texttt{LinearExtrapBnd.F}.
This code was written by Carsten Gundlach, and is taken directly from
the thorn \texttt{AEIThorns/Exact}. As such it illustrates a simple
way to properly implement a boundary condition using Fortran code
which was written long before the current boundary implementation
specification.
\section{Obtaining This Thorn}
This thorn is provided within the \texttt{CactusExamples} arrangement,
in the standard Cactus distribution.
\section{Some Details}
The \texttt{LinearExtrap} boundary condition registered by this thorn
only works in three dimensions. The value on a boundary face is
determined by fitting a straight line through the two points 'inside'
of the boundary point. For the edges and corners, two points along
the diagonal are used to determine the line. In this way the thorn
also provides an example of how to handle edges and corners, though
only in a dimension specific way.
\section{Using This Thorn}
To use this thorn, simply activate it in your parameter file, select
some variables for the \texttt{LinearExtrap} boundary condition, and
be sure that \texttt{ApplyBCs} (as e.g. \texttt{MyThorn\_ApplyBCs}) is
scheduled at an appropriate point.

% Cactus Thorn template for ThornGuide documentation
% Author: Ian Kelley
% Date: Sun Jun 02, 2002
% $Header$
%
% Thorn documentation in the latex file doc/documentation.tex
% will be included in ThornGuides built with the Cactus make system.
% The scripts employed by the make system automatically include
% pages about variables, parameters and scheduling parsed from the
% relevent thorn CCL files.
%
% This template contains guidelines which help to assure that your
% documentation will be correctly added to ThornGuides. More
% information is available in the Cactus UsersGuide.
%
% Guidelines:
% - Do not change anything before the line
% % START CACTUS THORNGUIDE",
% except for filling in the title, author, date etc. fields.
% - Each of these fields should only be on ONE line.
% - Author names should be sparated with a \\ or a comma
% - You can define your own macros, but they must appear after
% the START CACTUS THORNGUIDE line, and must not redefine standard
% latex commands.
% - To avoid name clashes with other thorns, 'labels', 'citations',
% 'references', and 'image' names should conform to the following
% convention:
% ARRANGEMENT_THORN_LABEL
% For example, an image wave.eps in the arrangement CactusWave and
% thorn WaveToyC should be renamed to CactusWave_WaveToyC_wave.eps
% - Graphics should only be included using the graphix package.
% More specifically, with the "includegraphics" command. Do
% not specify any graphic file extensions in your .tex file. This
% will allow us (later) to create a PDF version of the ThornGuide
% via pdflatex. |
% - References should be included with the latex "bibitem" command.
% - Use \begin{abstract}...\end{abstract} instead of \abstract{...}
% - Do not use \appendix, instead include any appendices you need as
% standard sections.
% - For the benefit of our Perl scripts, and for future extensions,
% please use simple latex.
%
% *======================================================================*

% Example of including a graphic image:

\section{Purpose}
\label{sec:purpose}
WaveToy is the simple test thorn that comes with Cactus as
standard. This is written so that it solves the wave equation
\begin{equation}
\label{eq:wave1}
\partial_t^2 \phi = \partial_{x^i}^2 \phi^i
\end{equation}
directly using the leapfrog scheme. This form of the equations isn't
suitable for use with the method of lines.
The purpose of this thorn is to rewrite the equations in first order
form
\begin{eqnarray}
\label{eq:wave2}
\partial_t \Phi & = & \partial_{x^i} \Pi^i, \\
\partial_t \Pi^j & = & \partial_{x^j} \Phi, \\
\partial_t \phi & = & \Phi, \\
\partial_{x^j} \phi & = & \Pi^j.
\end{eqnarray}
The first three equations (which expand to five separate PDEs) will be
evolved. The final equation is used to set the initial data and can be
thought of as a constraint.
This will be implemented using simple second order differencing in
space. Time evolution is performed by the method of lines thorn MoL.
\section{How it works}
\label{sec:details}
The equations are evolved entirely using the method of lines thorn. So
all we have to provide (for the evolution) is a method of calculating
the right hand side of equation~(\ref{eq:wave2}) and boundary
conditions. The boundary conditions are standard from wavetoy
itself. The right hand side is calculated using second order centred
finite differences.
To be compatible with the method of lines thorn we must let it know
that the GFs $(\phi, \Pi, \Phi^j)$ exist and where they are stored.
They should all have at least two time levels (although the addition
of extra time levels may not cause problems it's just wasting space).
The GFs corresponding to the right hand sides must also be registered
with the MoL thorn. These should only have one time level. MoL is
informed of the existence of these grid functions through the
accumulator parameters and the aliased functions.

This thorn contains enhancements to the standard WaveToy thorns for
modelling 3D scalar fields. WaveToy is primarily intended as a
example thorn and for that reason is deliberately kept as simple
as practical, with more advanced features included here instead.
Currently this thorn shows how more flexible boundaries can be
used with WaveToy or other thorns.

% Cactus Thorn template for ThornGuide documentation
% Author: Ian Kelley
% Date: Sun Jun 02, 2002
% $Header$
%
% Thorn documentation in the latex file doc/documentation.tex
% will be included in ThornGuides built with the Cactus make system.
% The scripts employed by the make system automatically include
% pages about variables, parameters and scheduling parsed from the
% relevent thorn CCL files.
%
% This template contains guidelines which help to assure that your
% documentation will be correctly added to ThornGuides. More
% information is available in the Cactus UsersGuide.
%
% Guidelines:
% - Do not change anything before the line
% % BEGIN CACTUS THORNGUIDE",
% except for filling in the title, author, date etc. fields.
% - You can define your own macros are OK, but they must appear after
% the BEGIN CACTUS THORNGUIDE line, and do not redefine standard
% latex commands.
% - To avoid name clashes with other thorns, 'labels', 'citations',
% 'references', and 'image' names should conform to the following
% convention:
% ARRANGEMENT_THORN_LABEL
% For example, an image wave.eps in the arrangement CactusWave and
% thorn WaveToyC should be renamed to CactusWave_WaveToyC_wave.eps
% - Graphics should only be included using the graphix package.
% More specifically, with the "includegraphics" command. Do
% not specify any graphic file extensions in your .tex file. This
% will allow us (later) to create a PDF version of the ThornGuide
% via pdflatex. |
% - References should be included with the latex "bibitem" command.
% - For the benefit of our Perl scripts, and for future extensions,
% please use simple latex.
%
% *======================================================================*
%
% Example of including a graphic image:
% \begin{figure}[ht]
% \begin{center}
% \includegraphics[width=6cm]{MyArrangement_MyThorn_MyFigure}
% \end{center}
% \caption{Illustration of this and that}
% \label{MyArrangement_MyThorn_MyLabel}
% \end{figure}
%
% Example of using a label:
% \label{MyArrangement_MyThorn_MyLabel}
%
% Example of a citation:
% \cite{MyArrangement_MyThorn_Author99}
%
% Example of including a reference
% \bibitem{MyArrangement_MyThorn_Author99}
