| | | | | | | | | | | add: it should be possible to set a mask to different values in the excised region, in the buffer zone between there & the AH, and outside the AH; also it should be possible to supress setting the mask (i.e. just leave it unchanged) in any subset of these git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1033 f88db872-0e4f-0410-b76b-b9085cfa78c5

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
