Things to do for this thorn
===========================
$Header$
----------------------------------------
Ian Hawke:
It would be nice to be able to output the difference between a
numerical evolution and the exact solution.
----------------------------------------
Sascha Husa:
It would be nice if Exact could set up variables other than the ADM ones
(indeed it appears to not even grok BSSN right now).
----------------------------------------
Sascha Husa:
The boundary setup needs to be generalized to handle ghost zones wider
than 1 point.
----------------------------------------
Every model should have .ge. 1 test case! Right now most of the
models have no test cases at all, and this makes it way too easy for
bugs to creep in and go undetected for a long time.
For models satisfying the Einstein eqns, it would be nice to also have
test cases which compute the Hamiltonian constraint (and maybe the
momentum constraints too) and check that it (they) are suitably small.
(The down side of that is that is that those test
cases would then need at least ADMConstraints
to be compiled into your Cactus binary, and that
in turn requires ADMMacros.)
This would help guard against typos, wrong formulas, and other
"consistent, but wrong" cases.
----------------------------------------
It would be nice if Exact supported fisheye.
Failing that, it could at least check if FishEye is active
and cleanly report an error.
----------------------------------------
It would be nice if Exact supported the "static conformal" metric type.
----------------------------------------
