origin, if desired
Introduce a new parameter that tests whether the refinement hierarchy is symmetric about the origin.
|
|
|
|
|
|
| |
Add new parameters symmetry_periodic_x, symmetry_periodic_y, and
symmetry_periodic_z that ensure that the generated grid structure has
the corresponding symmetry.

Correct errors for cell centered grids
Correct snap_to_coarse
Introduce veryverbose parameter

Use an illegal default value for the refinement region radii. This
catches parameter file errors where the radii are not set.

|

|

Don't allow 0 levels, because this would mean switching off the coarse
grid as well.
|
|
|
|
|
|
|
| |
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.

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.

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.

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.

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.

Regrid only if the tracked objects have moved a certain minimum
distance.

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.

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.

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.
