* Changed the grid function used in the flooding alogrithm (to find the numberdiener2006-01-10
| | | | | | | | | | of separate surfaces) from integer to real type in preparation to get the area calculation to work with Carpet. Introduced a module with fuzzy comparison routines. Testsuite still passes. Still needs to be tested in more complicated circumstances. Please report any problems. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/EHFinder/trunk@199 2a26948c-0e4f-0410-aee8-f1d3e353619c
* Made grid functions and variables private instead of public (I don't know whydiener2004-06-22
| | | | | | | | | | they were public in the first place). Added a USES INCLUDE carpet.h. Added tags='Prolongation="None"' to grid functions with only 1 timelevel. Added a grid scalar to count iterations in the re-initialization so that I can use the same variable in Fortran and C++. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/EHFinder/trunk@179 2a26948c-0e4f-0410-aee8-f1d3e353619c

| | | | | | | | | | | | | | integrals over all surfaces. Still only supports full mode. Only weakly tested. There is a problem with the outputs in multiprocessor mode. The results of the integration are stored in 1D grid arrays. However if I use DISTRIB=DEFAULT (taking care only to store results on the correct processor), the output fails if the number of processors are bigger than the number of elements in the grid array (essentially some processors contains a chunk of length zero). If I on the other hand uses DISTRIB=CONSTANT, it works but on multiple processors i get multiple copies of the data in the output. git-svn-id: http://svn.einsteintoolkit.org/cactus/EinsteinAnalysis/EHFinder/trunk@90 2a26948c-0e4f-0410-aee8-f1d3e353619c
