* Re-organise time level handlingErik Schnetter2011-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Store the current Cactus time (and not a fake Carpet time) in the th "time hiearchy". This removes the now redundant "leveltimes" data structure in Carpet. Add past time levels to th, so that it can store the time for past time levels instead of assuming the time step size is constant. This allows changing the time step size during evolution. Share the time hierarchy between all maps, instead of having one time hierarchy per map. Simplify the time level cycling and time stepping code used during evolution. Improve structure of the code that loops over time levels for certain schedule bins. Introduce a new Carpet variable "timelevel", similar to "reflevel". This also makes it possible to avoid time interpolation for the past time levels during regridding. The past time levels of the fine grid then remain aligned (in time) with the past time levels of the coarse grid. This is controlled by a new parameter "time_interpolation_during_regridding", which defaults to "yes" for backwards compatibility. Simplify the three time level initialisation. Instead of initialising all three time levels by taking altogether three time steps (forwards and backwards), initialise only one past time level by taking one time step backwards. The remaining time level is initialised during the first time step of the evolution, which begins by cycling time levels, which drops the non-initialised last time level anyway. Update Carpet and the mode handling correspondingly. Update the CarpetIOHDF5 checkpoint format correspondingly. Update CarpetInterp, CarpetReduce, and CarpetRegrid2 correspondingly. Update CarpetJacobi and CarpetMG correspondingly.

* CarpetReduce: Correct error in reduction operationsErik Schnetter2007-08-28
| | | | | | | | | | | | | Make the function initialise and reduce in the reduction operators handle the count argument as well. Introduce "combine" functions into the reduction operators. These combine results from several independent reduction operations. Use the above new functions to combine reductions, correcting an error. darcs-hash:20070828044751-dae7b-02070b6aa39d25fb91481ab6a9b45cf37b10fe2f.gz

* CarpetReduce: Implement pointwise reduction operatorsErik Schnetter2007-05-26
| | | | | | | | | | | | | | | | | | | | | | | | Implement a new set of reduction operators for Carpet. These have the same definitions as the old operators, except that they give the same weight to all grid points. The existing operators give a larger weight to coarser grid points, so that physical reduction operators work correctly, e.g. for calculating the total mass. The new operators have the same name as the old operators plus a prefix "i" (the lower case letter "eye"). For example, the new L2 norm is called "inorm2", while the old norm continues to be called "norm2". The physical (old) operators converge to a result which is independent of the grid structure. The pointwise (new) operators still converge, but to a value which depends on the grid structure. In order to make it possible to compare situations with and without symmetries, boundary points still carry a weight of 1/2 or whatever is appropriate. That means that there exists a simple relationship between the pointwise norms with and without a symmetry boundary. darcs-hash:20070526195016-dae7b-6a7e2a39bebd9c0a6377f908a4d7f446f8288191.gz
