Cactus Code Thorn Exact
Authors : Carsten Gundlach initially, plus many other authors.
Maintainer : Jonathan Thornburg <jthorn@aei.mpg.de>
CVS info : $Header$
--------------------------------------------------------------------------
Purpose of the thorn:
The initial purpose of this thorn was the comparison of numerical
spacetimes against exact solutions. One particular solution,
the boost-rotation-symmetric spacetimes, was the first application.
Later, the thorn developed as a reservoir for a variety of exact spacetimes,
some of them in different coordinate systems, and even some non-Einstein
spcetimes. All od these exact spacetimes have been found useful for
testing different aspect of the code. Since mamy different people have
contributed to this thorn by adding new exact solutions, you should expect
many different styles of coding here.
For more details see the comments in the param.ccl file, and the
documentation in the directory doc. For instructions on how to add
a new model, see doc/how_to_add_a_new_model.
Note that the June 2002 revisions to this thorn included renaming
most of the parameters. The perl script par/convert-par.pl will
convert old parameter files to use the new names, renaming the old
parameter files to ".par.bak" as backups.
