* At Ian Hawke's request, make the setting of an excision mask specifyablejthorn2003-12-03
| | | | | | | | | | | | | | | | on a per-horizon basis: The old parameter set_mask is now replaced by two new parameters: set_mask_for_all_horizons set_mask_for_individual_horizon[n] For most purposes, you can just change set_mask to set_mask_for_all_horizons in your parameter files. If you really want to control the setting of the mask on a per-horizon basis, read section 4.6 in the thorn guide to find out how the new parameters work. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1222 f88db872-0e4f-0410-b76b-b9085cfa78c5

* change from running in CCTK_POSTSTEP (which doesn't work with Carpet)jthorn2003-07-28
| | | | | | | | | | | | | | | | | to CCTK_ANALYSIS (which does, yea!) ... Alas, due to the @*(#&%@*&(%#$ "trigger" behavior of Cactus, the only way to force a routine to run in CCTK_ANALYSIS is to use a dummy I/O method to fake doing output at every time step. Fortunately, Erik Schnetter has already written the code for this, so AHFinderDirect now just used that. Thus AHFinderDirect now depends on thorn TAT/always. All thornlists and par files will have to be changed to compile in always and activate it before activating AHFinderDirect. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/AHFinderDirect/trunk@1156 f88db872-0e4f-0410-b76b-b9085cfa78c5
