* CarpetRegrid2: Ensure that the refinement hierarchy is symmetry about the ↵Erik Schnetter2012-09-11
| | | | | | origin, if desired Introduce a new parameter that tests whether the refinement hierarchy is symmetric about the origin.
* 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.

* CarpetRegrid2: Correct regridding for cell centeringErik Schnetter2011-12-14
| | | | | | Correct errors for cell centered grids Correct snap_to_coarse Introduce veryverbose parameter
* CarpetRegrid2: Use illegal default value for refinement region radiiErik Schnetter2011-12-14
| | | | | Use an illegal default value for the refinement region radii. This catches parameter file errors where the radii are not set.
* CarpetRegrid2: Allow rectangular (cuboid, non-cubic) refined regionsErik Schnetter2011-12-14
|
* CarpetRegrid2: Correct default number of refinement levelsErik Schnetter2008-10-01
| | | | | Don't allow 0 levels, because this would mean switching off the coarse grid as well.
* CarpetRegrid2: Add parameters to regrid only aligned refinement levelsErik Schnetter2008-08-28
| | | | | | | Add parameters to regrid only those refinement levels that exist at a particular time, and leave all coarser refinement levels unchanged. At the moment, this may lead to improperly nested grids if grids move too far.
* CarpetRegrid2: Add new parameter "boundary_shiftout"Erik Schnetter2008-01-28
| | | | | | | | | Add a new parameter "boundary_shiftout" which determines the number of grid points added to the refinement boundary radius. This allows refined regions which are larger or smaller than the radius by a certain number of points. darcs-hash:20080128041105-dae7b-77e435f5b46d6136b5eafff86796f97b46accc99.gz
* CarpetRegrid2: Remove STEERABLE tag from some parametersErik Schnetter2007-12-10

* CarpetRegrid2: Enforce regridding when the number of levels has changedErik Schnetter2007-09-27
| | | | | | | | | When using the movement_threshold parameters to regrid less often, still regrid when the number of levels has changed, or when a region has become active or inactive, or when the radius has changed significantly. darcs-hash:20070927164001-dae7b-d70720cb48753f0554f2301c4da2407d52ccb2f4.gz
* CarpetRegrid2: Add new parameter "active"Erik Schnetter2007-08-21
| | | | | | | | Add new parameters and grid scalars "active" for refined regions, which specify whether a region is active. This allows switching refined regions on and off, e.g. when a common horizon is found. darcs-hash:20070821191037-dae7b-8f5c0ec10326b5eb876fa8ccb7e3147b6fa2ff2f.gz
* CarpetRegrid2: Ensure and test proper nestingErik Schnetter2007-04-25
| | | | | | | | | | Introduce a parameter ensure_proper_nesting, which automatically enlarges the levels of the grid hierarchy to ensure proper nesting. (It does not enlarge the coarsest level.) If this parameter is not set, proper nesting is still tested, and a warning is emitted if it is violated. darcs-hash:20070425002649-dae7b-7431881af786bbae5048c5329807e90a4f7b2e29.gz
* CarpetRegrid2: Regrid only if the tracked objects have moved sufficientlyErik Schnetter2007-03-11
| | | | | | | Regrid only if the tracked objects have moved a certain minimum distance. darcs-hash:20070311204027-dae7b-7c39e3c51d6b617188b477aed73facd5fe7e6fe8.gz
* CarpetRegrid2: Allow up to 10 refined regionsErik Schnetter2007-03-11
| | | | darcs-hash:20070311184448-dae7b-67389684b8c83c29f7984b52d006d82741c385bd.gz
* CarpetRegrid2: Correct checkpointing error. Implement cell centering.Erik Schnetter2007-01-12
| | | | | | | | | | | | | | | Correct error with checkpointing and recovery. Store the last regridding iteration in grid variables, so that it is conserved during checkpointing and recovery. Implement cell centered refinement. Introduce a new parameter "snap_to_coarse" that makes the fine grid always cover complete coarse grid cells. Add a parameter "min_fraction" which specifies when to combine several small grids to form a single, larger, combined grid. darcs-hash:20070112233156-dae7b-3f32c9558e29f25f9bc1ba533985a4392877feab.gz
* CarpetRegrid2: Combine all components into a single one if that is efficientErik Schnetter2006-12-05
| | | | | | | | | | | Introduce a parameter "min_fraction" that defines, indirectly, how many additional refined grid points can be introduced if that leads to a simpler structure. If using a single refined region instead of several ones would not introduce too many unnecessarily refined grid points, then do so. darcs-hash:20061205175426-dae7b-18d2467cf123b734aaef19eb2f5f9c4994480b99.gz

* CarpetRegrid2: Introduce "verbose" parameterErik Schnetter2006-09-25
| | | | | | Introduce "verbose" parameter, defaulting to "no". darcs-hash:20060925220919-dae7b-448f3480758e89861c0201eefdaabbaab2808ece.gz
* CarpetRegrid2: New thornErik Schnetter2006-04-17
Add a new regridding thorn that works independently of CarpetRegrid. It is written more cleanly and easier to understand, but it has also fewer features. It is mostly intended for tracking objects that move in the domain. darcs-hash:20060417221723-dae7b-fb004dda04eae2d284388f1f1f660426ece37c20.gz
