Release 2022.04.04

Upgrade instructions

From #3766 (Stop computing errors inside ObserveFields, remove ObserveErrorNorms):

If you use ObserveErrorNorms, this is now replaced by ObserveNorms with specifying Error(variable). For example,

ObserveNorms:
  TensorsToObserve:
    - Name: Error(Psi)
      NormType: L2Norm
      Components: Sum
    - Name: Error(Phi)
      NormType: L2Norm
      Components: Sum
    - Name: Error(Pi)
      NormType: L2Norm
      Components: Sum

When writing executables, follow the example in EvolveScalarWave to see how to replace ObserveErrorNorms by ObserveNorms.

From #3832 (Delete thin wrappers around blaze::DynamicVector/Matrix):

If you used DenseVector/Matrix replace them with blaze::DynamicVector/Matrix. Use the includes DataStructures/Dynamic{Vector,Matrix}.hpp if you need support for serialization, make_with_value or option-creation, or include <blaze/math/Dynamic{Vector,Matrix}.h> directly if you don't need those features.

From #3817 (Use quaternion rotation map in BinaryCompactObject domain creator):

When specifying input options for the BinaryCompactObject domain creator, replace

RotationAboutZAxisMap:
  InitialRotationAngle: 1.0
  InitialAngularVelocity: -0.5

with

RotationMap:
  InitialAngularVelocity: [0.0, 0.0, -0.5]

Note: The initial rotation angle is now always assumed to be zero and cannot be specified by the user.

From #3876 (Consolidate mutation of global cache into single function):

To mutate a mutable global cache tag Tag, use Parallel::mutate<Tag, Functor>(cache, args...) where cache is a reference to the local GlobalCache. This works in both the testing framework and charm-aware situations.

From #3882 (Omit BBH domain cube-to-sphere transition):

If you use the BinaryCompactObject domain, try setting EnvelopingCube.Sphericity = 1 and OuterShell.InnerRadius = Auto. This configuration transitions from the two inner objects to the outer spherical shell in a single layer of blocks, which can greatly improve the effectiveness of grid points in the domain.

From #3902 (post_horizon_find_callbacks is now a tmpl::list.):

post_horizon_find_callback needs to be changed to post_horizon_find_callbacks, and is
a tmpl::list of structs instead of a single struct.

From #3838 (Change ASSERT and ERROR to throw an exception instead of aborting):

If you have an ASSERTION_TEST or ERROR_TEST as a separate SPECTRE_TEST_CASE, they should be combined with the standard SPECTRE_TEST_CASE by calling CHECK_THROWS_WITH (see the Catch documentation for usage)

Release 2022.02.17

Upgrade instructions

From #3768 (Remove TimeDependence/Composition.?pp):

There is no more Composition TimeDependence. If a composition of simple maps is desired, then it should be written explicitly.

From #3799 (Functions in ApparentHorizons/Tags.cpp are now free functions.):

Release 2022.02.08

Upgrade instructions

From #3712 (Update installation instructions, add Spack env file, upgrade container):

To compile the Doxygen documentation, upgrade to the recently released bugfix version 1.9.3. Earlier versions also work, but the documentation may not look the same as on https://spectre-code.org.

From #3720 (Disable IWYU by default):

To enable IWYU, set -D USE_IWYU=ON in your CMake config.

From #3715 (Allow experimental builds with Charm++ 7):

Builds with Charm++ 7 are now allowed, meaning the SpECTRE build system now accepts Charm++ 7 installations. Builds with Charm++ 7 are still experimental, so please file or fix issues you encounter.

From #2680 (Link Charm++ as a CMake target):

We link Charm++ like any other external dependency now. In particular:

• If you include <pup.h>, add Charmxx::pup to target_link_libraries.
• If you include <charm++.h>, add Charmxx::charmxx to target_link_libraries.

It is now easier to link Charm++ shared libraries, which can significantly reduce the size of builds. To take advantage of this, build Charm++ with the --build-shared flag and configure the SpECTRE build with -D BUILD_SHARED_LIBS=ON.

From #3740 (Move testing Parallel::mutate to ActionTesting):

In tests, instead of calling Parallel::mutate(cache), now call ActionTesting::mutate(cache).

From #3741 (Clarify center() function of strahlkorper as expansion_center()):

Strahlkorper now has its center() function renamed to expansion_center()

Release 2021.11.01

Upgrade instructions

From #3570 (Support 1/r radial distribution in BBH domain outer shell):

• When constructing a BinaryCompactObject domain from options, move the UseProjectiveMap option into the EnvelopingCube group. Furthermore, the options for the outer spherical shell have changed to support more radial distributions. If you had these options before:

  # Old
  EnvelopingCube:
    Radius: 55.
  UseProjectiveMap: True
  OuterSphere:
    Radius: 300.
    UseLogarithmicMap: False

  adjust them like this:

  # New
  EnvelopingCube:
    Radius: 55.
    UseProjectiveMap: True
  OuterShell:
    InnerRadius: Auto  # you can specify the first spherical radius explicitly now, or use the default
    OuterRadius: 300.
    RadialDistribution: Linear  # You can also set this to `Logarithmic` or `Inverse`

From #3583 (Add IndexPolarAxis Option to Shell Domain):

The Shell constructor has been changed such than an additional argument index_polar_axis (additional Option IndexPolarAxis) must be passed following the argument aspect_ratio (Option AspectRatio). The default value is set to 2 (the z axis).

From #3617 (Move YlmSpherepack to NumericalAlgorithms/SphericalHarmonics.):

YlmSpherepack is now in the library NumericalAlgorithms/SphericalHarmonics.

If you use Frame::Logical this will now need to be either Frame::BlockLogical or Frame::ElementLogical depending upon which of the two frames the map uses or tensor represents.

From #3507 (Add block names to BinaryCompactObject domain, support per-block refinement):

When constructing a BinaryCompactObject domain creator from options, delete the AdditionToRadialRefinementLevel options. They have been replaced by per-block support for the InitialRefinement and InitialGridPoints options.

• If you used no additional radial refinement before, you can just delete the options:

  # New - uniform refinement
  DomainCreator:
    BinaryCompactObject:
      # ... (delete AdditionToRadialRefinementLevel options)
      InitialRefinement: 1

• If you had this additional radial refinement configuration before:

  # Old - additional radial refinement
  DomainCreator:
    BinaryCompactObject:
      ObjectA:
        # ...
        AdditionToRadialRefinementLevel: 1
      # ...
      OuterSphere:
        # ...
        AdditionToRadialRefinementLevel: 2
      InitialRefinement: 1

  you can reproduce it now with these options:

  # New - additional radial refinement
  DomainCreator:
    BinaryCompactObject:
      # ...
      InitialRefinement:
        ObjectAShell:   [1, 1, 2]
        ObjectBShell:   [1, 1, 1]
        ObjectACube:    [1, 1, 1]
        ObjectBCube:    [1, 1, 1]
        EnvelopingCube: [1, 1, 1]
        CubedShell:     [1, 1, 1]
        OuterShell:     [1, 1, 3]

Refer to the help string of the BinaryCompactObject domain creator for details.
