* support named spherical surfacesrhaas2012-01-24
| | | | git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1562 f88db872-0e4f-0410-b76b-b9085cfa78c5
* Change the number of timelevels of the ahmask to match the number which is ↵knarf2011-01-25
| | | | | | | | | | | used for the metric. Setting this to three unconditionally leads to problems when running with Carpet and prolongation_order_time=1 because all GFs in Carpet are expected to have the same number of timelevels: prolongation_order_time+1. This is not the ideal solution. That would eliminate also variables ala metric_timelevels, because they directly depend on prolongation_order_time and should not have to be set (correctly) in a parameter file. This could be done automatically. However, this patch for now uses metric_timelevels, in order to get AHFinderDirect working quickly. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1554 f88db872-0e4f-0410-b76b-b9085cfa78c5
* Patch from Bruno Giacomazzo:knarf2010-08-10
| | | | | | | | | | | | | | the patch allows the possibility to schedule AHFinderDirect also at POSTPOSTINITIAL by adding the parameter run_at_CCTK_POSTPOSTINITIAL (default equals to false). I have used it to be sure that an AH was found after initial data computation and before the last call to the Con2Prim routine of Whisky before evolution was started (in order to have hydro variables properly excised before the beginning of the evolution). git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1550 f88db872-0e4f-0410-b76b-b9085cfa78c5

* fix a bug found by Yosef Zlochower:jthorn2005-06-14
| | | | | | | | | | | | | | | | | | | | | | In a multiprocessor run, AHFinderDirect finds different horizons in parallel on different processors, and doesn't broadcast horizon shapes to all processors unless it thinks they'll be needed. However, the "the information will be needed" calculation doesn't take into account the possibility of the HorizonRadiusInDirection() aliased function being called on another processor, and in this case this function returns a wrong result if AHFinderDirect hasn't broadcast the horizon shapes. * introduce a new Boolean parameter always_broadcast_horizon_shape (defaults to false) * document in interface.ccl, param.ccl, and doc/documentation.tex, that this parameter should be set to true if you expect HorizonRadiusInDirection() to be used * inclusive-or this parameter into the "should we broadcast the horizon shape?" calculation in src/driver/find_horizons.cc git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1419 f88db872-0e4f-0410-b76b-b9085cfa78c5

* change the default geometry interpolator from order 3 down to order 2jthorn2003-08-12
| | | | | | | | | | | | this will make AHFinderDirect faster (typically about 2.5 times faster), but less accurate (on analytic data at dx=0.1m or so, typical accuracies of 1e-4m or so, instead of 1e-5m or so for order=3). In practice, for most of our runs the AHFinderDirect (in)accuracy is dominated by the inaccuracy of the numerically computed g_ij and K_ij fed into it, so the slightly lower AH-finding accuracy is unimportant. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1178 f88db872-0e4f-0410-b76b-b9085cfa78c5
