v0.9.5

0.9.5 Release Highlights

(adapted from Conduit's Changelog )

Released 2025-09-10

Added

Blueprint

• Added support for unstructured topologies with mixed shape type in the conduit::blueprint::mesh::partition() and conduit::blueprint::mesh::utils::topology::iterate_elements() functions. They work with mixed shape types, including polyhedra.
• Added conduit::blueprint::mesh::utils::topology::compute_mesh_info() function to compute basic information about a mesh such as extents and edge lengths.
• Added conduit::blueprint::mesh::utils::topology::Quantizer class to compute a quantized index for a point.
• Added bent_multi_grid_amr example mesh. This enhances the bent_multi_grid example to allow a user to specify, in one of the domains, a nested domain with its ID and refinement ratio. This will allow example AMR meshes.

Relay

• Added flush method to relay::IOHandle interface. Semantics differ between concrete implementations.
• Added flush support to relay::BasicIOHandle, allows write to file system without closing the handle.
• Added flush support to relay::HDF5Handle, if hdf5 file handle is open, invokes H5Fflush() with H5F_SCOPE_LOCAL.
• Added namescheme read and write support to the Relay Silo/Overlink Reader/Writer.
• Added support for block types or unified types to the Relay Silo/Overlink Reader/Writer.

Changed

General

• Updates to spack uberenv recipes for macOS 15.5.

Blueprint

• The conduit::blueprint::mesh::topology::dims() function was changed so it will return the maximum topological dimension of the shape types from the shape_map for a mixed shape.
• Enhanced the conduit::blueprint::mesh::examples::tiled() function so it can accept mesh tiles containing mixed shape types for generating 2D tiled output.
• Adjacency set construction was altered so points are sorted spatially using the Quantizer class.

Fixed

Relay

• Fixed an issue with the Overlink Writer preventing it from correctly writing out data in the n files to m domains case.
