* CarpetLib: Change API to obtain pointer to grid function dataErik Schnetter2012-09-11
| | | | | | | | Change the API to obtain a pointer to grid function data: - Use a function "typed_data_pointer" instead of overloading the () operator (because this looks nicer) - Don't use a virtual function (because this isn't needed) - Update all uses

* Introduce a tree data structure to speed up domain decompositionErik Schnetter2008-06-20
| | | | | | | | | Introduce a tree data structure "fulltree", which decomposes a single, rectangular region into a tree of non-overlapping, rectangular sub-regions. Move the processor decomposition from the regridding thorns into Carpet. Create such trees during processor decomposition. Store these trees with the grid hierarchy.

* global: Add varying refinement factorsErik Schnetter2005-05-01
| | | | | | | | | | Add support for varying refinement factors. The spatial refinement factors can be different in different directions, can be different from the time refinement factor, and can be different on each level. (However, the underlying spatial transport operators do currently not handle any factors except two.) darcs-hash:20050501205010-891bb-8d3a74abaad55ee6c77ef18d51fca2a2b69740de.gz

* global: Change the way in which the grid hierarchy is storedErik Schnetter2005-02-01
| | | | | | | | | | | | | | | | | | | | Change the way in which the grid hierarchy is stored. The new hierarchy is map mglevel reflevel component timelevel i.e., mglevel moved from the bottom to almost the top. This is because mglevel used to be a true multigrid level, but is now meant to be a convergence level. Do not allocate all storage all the time. Allow storage to be switched on an off per refinement level (and for a single mglevel, which prompted the change above). Handle storage management with CCTK_{In,De}creaseGroupStorage instead of CCTK_{En,Dis}ableGroupStorage. darcs-hash:20050201225827-891bb-eae3b6bd092ae8d6b5e49be84c6f09f0e882933e.gz
* global: Turn CarpetLib templates into classesErik Schnetter2005-01-01
| | | | | | | | | | | | | | | | | | | Turn most of the templates in CarpetLib, which used to have the form template<int D> class XXX into classes, i.e., into something like class XXX by setting D to the new global integer constant dim, which in turn is set to 3. The templates gf and data, which used to be of the form template<typename T, int D> class XXX are now of the form template<typename T> class XXX The templates vect, bbox, and bboxset remain templates. This change simplifies the code somewhat. darcs-hash:20050101182234-891bb-c3063528841f0d078b12cc506309ea27d8ce730d.gz

* CarpetLib:gh exposed data clamp-downswhite2004-12-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | Made all variables in CarpetLib:gh to be const or non-public, to avoid confusion and insanity. Toward this end, created four member accessors for gh: const rexts & extents() const const rbnds & outer_boundaries() const const rprocs & processors() const const vector<vector<ibbox> > & bases() const This involved a few changes in several files throughout the repository: M ./Carpet/Carpet/src/Initialise.cc -2 +2 M ./Carpet/Carpet/src/Recompose.cc -8 +8 M ./Carpet/Carpet/src/SetupGH.cc -2 +2 M ./Carpet/Carpet/src/modes.cc -3 +3 M ./Carpet/CarpetIOHDF5/src/Recover.cc -4 +4 M ./Carpet/CarpetInterp/src/interp.cc -5 +5 M ./Carpet/CarpetLib/src/dh.cc -3 +3 M ./Carpet/CarpetLib/src/gh.cc -33 +33 M ./Carpet/CarpetLib/src/gh.hh -10 +28 M ./Carpet/CarpetReduce/src/mask_carpet.cc -4 +4 M ./Carpet/CarpetRegrid/src/automatic.cc -2 +2 darcs-hash:20041210131459-32473-ff0835ff0e57f6693fbe1ec23b350d1b1d18e3bc.gz

| | | | | | | | | | | | Remove the parameters Carpet::prolongate_initial_data; this is now always done. Remove arguments initialise_from and do_prolongate from Regrid(). Regridding is now done in level mode instead of meta mode. Furthermore, CarpetRegrid is called in singlemape mode. darcs-hash:20040418112943-07bb3-2e392df1737ab75f3f0d553bb53bde2ed41f8773.gz
* Import the recently announced changes:schnetter2004-01-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Import the recently announced changes: 1. Carpet has now an infrastructure for multiple maps (aka "grid patches"). Instead of a single grid hierarchy there can now be several. This is largely untested, because the remainder of Cactus cannot handle multiple coordinate systems. 2. The order in which the schedule bins are called has changed. As Ian Hawke pointed out, the previous order during time evolution was inconsistent. The initial data ordering did not allow for recovering and was not usable for progressively solving elliptic equations for initial data. 3. Carpet now supports convergence levels. The convergence level specifies by how many factors of two the resolution in the parameter file should be coarsened (or refined, if negative). This should make convergence tests and test runs much easier. It is, in principle, also possible to run several convergence levels at once. This has not been tested because the remainder of Cactus cannot handle multiple resolutions. This will be necessary for a multigrid solver, and also for having a shadow hierarchy to determine where to refine adaptively. 4. Carpet works together with the new CoordBase domain specification parameters. Without these, using convergence levels will lead to very strange results. 5. The "modes" have changed. There are now: meta mode: the whole simulation global mode: one convergence level level mode: one refinement level singlemap mode: one map on one refinement level local mode: as previously The whole mode handling has been cleaned up. 6. The regridding thorn has been cleaned up. 7. The kind of prolongation stencil is now determined in Carpet, i.e. at a fairly hight level, instead of in CarpetLib. 8. The low-order prolongation operators have been made much more efficient (as have previously the higher-order ones). 9. Assorted smaller changes. For Carpet users, there should be no major incompatibilities. The major improvements are 3 and 4 combined. Here is an example: CoordBase::domainsize = extent CoordBase::spacing = gridspacing CoordBase::zero_origin_x = yes CoordBase::zero_origin_y = yes CoordBase::zero_origin_z = yes CoordBase::xextent = 20.0 CoordBase::yextent = 20.0 CoordBase::zextent = 20.0 CoordBase::dx = 1.0 CoordBase::dy = 1.0 CoordBase::dz = 1.0 CoordBase::boundary_shiftout_x_lower = 1 CoordBase::boundary_shiftout_y_lower = 1 CoordBase::boundary_shiftout_z_lower = 1 Carpet::domain_from_coordbase = yes Carpet::convergence_level = 0 grid::type = coordbase grid::domain = octant grid::avoid_origin = no This gives you a grid that extends from the origin ("zero_origin") up to 20.0 with a grid spacing of 1.0. Symmetry zones and boundary zones are added automatically. The "shiftout" says that there is no boundary point on the origin. The staggering parameters (not shown) default to "no". In order to change the resolution, only the convergence level has to be adjusted. Note that the old way of specifying the domain extent still works. For Carpet developers, one major change is the new mode handling. As described in 5, the looping macros (that loop over all refinement levels, or all components) have changed. darcs-hash:20040125135727-07bb3-51c9647c1b5080e7e180b52a1b81fa155cfd19e9.gz
