Please download the Axom-*.tar.gz tarball below, which includes all of the Axom submodules as well. The AxomData-*.tar.gz tarball contains extra files to put in the data directory only if you want to run certain Axom tests.

Added

• Added a new "Mir" Axom component for accelerated Material Interface Reconstruction (MIR) algorithms.
  MIR algorithms take Blueprint meshes with a matset and they use the matset's material information
  to split any input zones that contain multiple materials into zones that contain a single material.
  The Mir component provides an implementation of the Equi-Z MIR algorithm, which is a visualization-
  oriented algorithm that produces smooth interfaces between zones and their neighbors. The Mir
  component also provides a 2D ELVIRA algorithm, which reconstructs polygonal shapes and preserves
  volume fractions.
• Support in quest::IntersectionShaper for Blueprint mesh stored in a conduit::Node
  or sidre::Group.
• Adds new CMake configuration options, AXOM_ENABLE_ASAN and AXOM_ENABLE_UBSAN, to enable/disable AddressSanitizer and UndefinedBehaviorSanitizer respectively in Axom. Default is OFF for both.
• A number of new klee::Geometry constructors are added, for the different shapes now supported.
  This is a temporary change. The class will be subclassed in the future to support a diversity of geometries.
• Support some analytical shapes in IntersectionShaper.
• Support generating shapes in memory (not requiring input files).
• sidre::View holding array data may now be re-shaped. See sidre::View::reshapeArray.
• Sina C++ library is now a component of Axom
• Adds optional dependency on Open Cascade. The initial intention is
  to use Open Cascade's file I/O capabilities in support of Quest applications.
• Adds primal::NURBSCurve and primal::NURBSPatch classes, supported by primal::KnotVector.
• Adds a Quest example that reads in a STEP file using Open Cascade and processes its geometry
• Adds a piecewise method to load external data using sidre::IOManager. This adds new overloaded methods
  of loadExternalData in sidre::IOManager and sidre::Group.
• Adds intersection routines between primal::Ray objects and primal::NURBSCurve/primal::NURBSPatch objects.
• Adds LineFileTagCombiner to Lumberjack to allow combining messages if line number, file, and tag are equal.
• Adds some support for 2D shaping in quest::IntersectionShaper, using STL meshes with zero for z-coordinates or in-memory triangles as input.
• Adds ability in Lumberjack to own and set communicators.
• Adds NonCollectiveRootCommunicator to Lumberjack to provide an MPI-based communicator for logging messages non-collectively.

Changed

• Updates blt submodule to [BLT version 0.7.0][https://github.com/LLNL/blt/releases/tag/v0.7.0]
• Updates to [MFEM version 4.7.0][https://github.com/mfem/mfem/releases/tag/v4.7]
• Updates to [Caliper version 2.12.1][https://github.com/LLNL/Caliper/releases/tag/v2.12.1]
• Updates to [Conduit version 0.9.3][https://github.com/LLNL/conduit/releases/tag/v0.9.3]
• Updates to [RAJA version 2025.03.0][https://github.com/LLNL/RAJA/releases/tag/v2025.03.0]
• Updates to [camp version 2025.03.0][https://github.com/LLNL/camp/releases/tag/v2025.03.0]
• Updates to [Umpire version 2025.03.0][https://github.com/LLNL/Umpire/releases/tag/v2025.03.0]
• primal::NumericArray has been moved to core. The header is core/NumericArray.hpp.
• quest::Shaper and quest::IntersectionShaper constructors require a runtime policy.
  Changing the policy after construction is no longer supported.
• Importing Conduit array data into sidre::View now allocates destination
  data using the View's parent's allocator ID, instead of always using
  host memory. This is consistent with the behavior of deep-copying data
  from Sidre.
• ItemCollection and its child classes MapCollection, ListCollection, and IndexedCollection were moved from Sidre
  to core. The namespace prefix for these classes is now axom:: instead of axom::sidre. The internal usage of
  these types within Sidre Datastore and Group is unchanged.
• MFEMSidreDataCollection::LoadExternalData now takes two optional string parameters, one that is a
  filename (defaults to the name member variable) and the other is a Group path relative to the base of
  the Data Collection itself (defaults to the root of the DataStore).
• SLIC_ASSERT,SLIC_ASSERT_MSG,SLIC_CHECK, and SLIC_CHECK_MSG macros delegate to assert() within HIP device kernels.

Fixed

• Fixes compilation issue with RAJA@2024.07 on 32-bit Windows configurations.
  This required a RAJA fix to avoid 64-bit intrinsics,
  as well as support for 32-bit Words in Slam's BitSet class.
• Minor bugfix to primal::intersect(segment, ray) to better handle cases when segment and ray overlap.
• Fixes a memory leak in axom::Array copy constructor.
