| * CarpetRegrid2: Correct min_fractionErik Schnetter2013-01-24
| | | | | | | | A condition was reversed, inverting the meaning of min_fraction, possibly leading to quite inefficient grid structures.

* | CarpetRegrid2: Allow pseudo-2D domainsFrank Löffler2013-02-07
|/ | | | | | | Currently CarpetRegrid2 contains two asserts that fail for domains that are effectively 2D (but defines as 3D arrays, e.g. (nx,ny,1). This patch makes sure these domains don't trigger the assert by checking for ilower==iupper.

* CarpetRegrid2: Perform domain decomposition only when a refinement level changesErik Schnetter2012-10-23
| | | | Compare new to old refined regions for each refinement level. Don't perform domain decomposition if a level didn't change. If no level changed, tell Carpet.

* Move MPI support from flesh to a thornErik Schnetter2012-09-11
| | | | | | | Move MPI support from flesh to thorn ExternalLibraries/MPI. This also requires thorns that call MPI directly to declare this in their configuration.ccl. Existing configurations using MPI need to include ExternalLibraries/MPI into their thorn list.

* Introduce cctk_ash, retire cctk_lsshErik Schnetter2012-09-11
| | | | | | | | | Introduce cctk_ash, describing the process-local array shape that has been allocated. This may be larger than cctk_lsh, the process-local shape that should be used. Retire cctk_lssh and related infrastructure to handle staggered grid functions.

* CarpetRegrid2: Add periodic boundary conditionsErik Schnetter2012-09-11
| | | | | | Add new parameters symmetry_periodic_x, symmetry_periodic_y, and symmetry_periodic_z that ensure that the generated grid structure has the corresponding symmetry.
* Re-organise some refluxing internalsErik Schnetter2012-09-11
| | | | | | | | | | | Re-organise some of the internal details of refluxing. Refluxing requires restricting fluxes from fine to coarse grids. Previously, Carpet would internally store bounding boxes that were offset by 1/2 grid point, and adjust (correct) these boxes in various places in a rather ad-hoc manner. This is now cleaned up. Remove the (unused) "accumulate" operator, and the (unused) "accumulate" prolongation type.

* CarpetRegrid2: Ignore non-symmetry if it is outside of the domainErik Schnetter2011-12-14
| | | | | | When testing whether refined region has a rotating-90 or rotating-180 symmetry, ignore non-symmetries that are outside of the simulation domain (because these are irrelevant).

* CarpetRegrid2: Enforce certain grid hierarchy propertiesErik Schnetter2011-12-14
| | | | | | | | | | | | | | | | | | | | Enforce certain grid structure properites, and ensure that they hold after being enforced. This change may lead to Carpet using a (slightly) different grid structure than before. The differences are not "important"; what potentially changes is the order in which consistency conditions are applied. I expect that, in most cases, there will be no differences. The list of consistency conditions is: - ensure proper nesting (level must be larger than next finer level) - add buffer zones (only once, not really a consistency condition) - combine regions into a single box (if this is efficient) - apply rotating 90/180 symmetry (if requested) - clip at outer boundary (so that boxes that are too large or are outside are cut off) This change also reorganises the code in CarpetRegrid2.
