| | | | | | | | | | | | | read IO parameters to set (default) directory in which we write output files and a medium thing if two apparent horizons appear together, then move apart, right now even with N_horizons > 1 we will probably have each of our AHs track the same one; there should be some way to say "use AH 1 + something as the initial guess for AH2" or suchlike, so we could find both AHs git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@876 f88db872-0e4f-0410-b76b-b9085cfa78c5

* * Move suboptions out of top-level "method" parameter into separatejthorn2002-10-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | parameters; the top-level method parameter is now just keyword method "what should this thorn do for each apparent horizon?" { # these options are mostly for testing/debugging "horizon function" :: "evaluate the LHS function H(h)" "test Jacobian" :: "compute/print the J[H(h)] Jacobian matrix" # this is for normal apparent horizon finding "find horizon" :: "find the apparent horizon" } "find horizon" The keyword strings have changed a bit, but since most users will not need to change the default value, this shouldn't change their parameter files. * Revise driver logic to clean up handling of the different values of the top-level method parameter. * Slightly tweak output format for BH diagnostics, and documentation (thorn guide) to make it explicit that what we're calculating is the irreducible mass of the apparent horizon.
