Added

  • Adds MarchingCubes class implementing the marching cubes algorithm for surface detection.
  • Adds the following methods to axom::Array to conform more closely with the std::vector interface:
    • Array::front(): returns a reference to the first element
    • Array::back(): returns a reference to the last element
    • Array::resize(size, T value): resizes the array, and sets any new elements to value.
  • Adds an ArrayView::empty() method to return whether the view is empty or not.
  • Adds an area() function to primal::Polygon
  • Adds initial support for using Slam types on the GPU
  • Adds support for using ArrayViewIndirection indirection policy with slam::Map and slam::BivariateMap
  • Adds const_iterator support to slam::BivariateMap and slam::SubMap
  • Primal: Adds a Hexahedron primitive
  • Primal: Adds a clip() operator for computing the intersection of a Hexahedron and another Tetrahedron as a Polyhedron
  • Primal: Adds an intersection_volume() operator for computing the volume of intersection between a primitive and a Tetrahedron
  • Primal: Adds a primal::Polyhedron::from_primitive() operator that returns a Polyhedron object from a given primitive.
  • Adds DataStore::getBufferInfo() and Group::getDataInfo() methods that insert information into a Conduit Node about buffers in a DataStore object or data in a Group subtree. The information can be accessed from the Node by the caller from specifically named fields in the Node.
  • Quest: Adds a quest::ProEReader for reading in Pro/E tetrahedral meshes
  • Quest: The quest::IntersectionShaper class can now use a percent error to determine whether the revolved volume for a shape is sufficiently accurate or whether the shape must be further refined. This new dynamic method of shaping complements the existing segment-based curve refinement method and it is activated using Shaper::setRefinementType() and by calling Shaper::setPercentError() to set a refinement error percentage.
  • Multimat: adds initial support for fields stored on the GPU. MultiMat::setAllocatorID() or MultiMat::setFieldAllocatorID() can be called to change the memory space in which a field is allocated.
  • Multimat: adds an MultiMat::addExternalField() function to support fields where the memory is managed externally. Fields which are externally-managed cannot be transposed between sparse and dense layouts, or moved between allocator spaces.
  • Multimat: adds a MultiMat::removeField() function to remove fields from the Multimat instance.
  • Multimat: adds an overload of MultiMat::setCellMatRel() that supports setting a multi-material relation in a compressed sparse-row (CSR) representation.
  • Quest: Adds ability to import volume fractions into SamplingShaper before processing Klee input
  • Slam: adds a slam::MappedVariableCardinality policy to accelerate mapping flat indices back to first-set indices when used in a StaticRelation
  • Adds an ArrayView(data, shape, strides) constructor to support column-major and custom striding layouts.
  • Adds an ArrayView::subspan() overload for multi-dimensional subspans
  • Adds an axom::utilities::insertionSort() method.
  • Quest: Adds Pro/E tetrahedral meshes as input to the IntersectionShaper
  • Quest: For sample-based shaping, users can register callback functions to modify the input points before querying the spatial index. This allows, e.g. querying 3D points against 2D surfaces of revolution provided as c2c contour files.
  • Adds an axom::utilities::locale utility function to guard against platforms that do not have the requested locales via the std::locale function. If the system does not have the requested locale (e.g. en_US.UTF8), it returns the user's default locale.
  • Sidre: Add new protocols sidre_layout_json and conduit_layout_json to provide output of DataStore layout in a user-readable format that excludes the numerical arrays held by Views and Buffers.
  • Sidre: Add methods to methods for destroying Groups that will also destroy Buffers if the destruction of a Group and the Views in its subtree cause the Buffer to become detached from all Views.
  • Sidre: Add two Group methods -- one to return a vector of the valid I/O protocols (based on compilation options), and one that returns a default protocol.
  • Klee: Add support in shaping driver and MFEMSidreDataCollection to write Blueprint datasets that contain matset metadata needed for VisIt to treat volume fraction arrays as a material. This enables VisIt plots such as FilledBoundary.

Changed

  • Fixed bug in mint::mesh::UnstructuredMesh constructors, affecting capacity. A missing factor was added. If you worked around this by adding the factor yourself, you may want to undo that work-around.
  • Updates blt submodule to [email protected]
  • Updates uberenv submodule to HEAD of main on 12May2023
  • Updates to conduit version 0.8.6
  • Updates to mfem version 4.5
  • Updates to fmt version 9.1.0
  • Updates to c2c version 1.8.0
  • The Axom library has been broken down into its component libraries (prefixed with axom_). This change requires no change to downstream CMake users who import our targets. The exported CMake target axom includes all components, but users who do not import our targets will need to create the link line themselves. The following replacement can be used: -laxom -> -laxom_quest -laxom_multimat -laxom_slam -laxom_mint -laxom_klee -laxom_inlet -laxom_sidre -laxom_slic -laxom_lumberjack -laxom_core. If you only need a subset of the components, you can now use those targets directly, ie. axom::inlet.
  • IntersectionShaper now implements material replacement rules.
  • axom::Array move constructors are now noexcept.
  • Exported CMake targets, cli11, fmt, sol, and sparsehash, have been prefixed with axom:: to guard against conflicts.
  • DistributedClosestPoint query now supports any blueprint-valid mesh format, including multidomain. Domain underloading and overloading can be expressed using multidomain format. Closest points are identified by cp_rank, cp_domain_index, and cp_index. The new cp_domain_index specifies the domain containing the closest point.
  • DistributedClosestPoint interfacing variable names closest_point and min_distance have been changed to cp_coords and cp_distance, respectively, to match the naming convention of other interfacing variables.
  • Adds vcpkg ports for RAJA, Umpire with optional OpenMP feature for automated Windows build.
  • Reduce size of ArrayView::subspan to prevent accessing invalid memory.
  • Adds vcpkg port for lua as optional dependency on Windows.
  • Adds additional parameters to quest's PointInCell query to control the Newton solve from physical to reference space for a given element.
  • Remove function pointer call in IteratorBase::advance().
  • Slam: IndirectionPolicy::data() now returns a reference to the underlying buffer. Rebinding an indirection to a new buffer is now achieved through IndirectionPolicy::ptr(), which returns a mutable pointer to the buffer.
  • Quest: Shaper::applyTransforms() is no longer a public method.
  • Multimat: fields are now returned as shallow, device-copyable views of a field instead of full copies of field data.
  • Multimat: MultiMat::addField() and MultiMat::setVolfracField() API now use axom::ArrayView to accept data.
  • Multimat: Ported field data/sparsity layout conversion methods to GPU.
  • Multimat: MultiMat::makeOtherRelation() now runs on the GPU with an appropriately-set allocator ID.
  • Multimat: MultiMat::setCellMatRel(counts, indices) now runs on the GPU, and accepts GPU-side data.
  • Renames ArrayView::spacing() to ArrayView::minStride().
  • Klee: A shape's geometry no longer needs a path field when its format is "none"
  • Quest: Shapes without geometry can participate in replacement rules for sample-based shaping. Volume fractions for the associated materials must be supplied before shaping.
  • Primal: Expose Polyhedron::getFaces() as public method.
  • Removed custom Spack package recipes in favor of using the radiuss-spack-configs repository as a submodule.

Fixed

  • Fixed issues with CUDA build in CMake versions 3.14.5 and above. Now require CMake 3.18+ for CUDA and non-gpu builds.
  • Fix to allow Axom to build when using RAJA, but not Umpire.
  • Checks validity of bounding boxes in primal intersection operators against planes and triangles before using the geometry.
  • Improves import logic for lua dependency
  • Improves import logic for mfem dependency in device builds when mfem is configured with caliper
  • Fixes ambiguity when calling Array::resize(size, value) for Array<bool>
  • Sidre: Group methods hasChildView() and hasChildGroup() changed to return false when Group holds items in list format. This fixes an IOManager issue causing failures for multi-domain meshes when writing Blueprint index file.
  • Sidre: Changed Group::copyToConduitNode() method to properly handle Groups using the list format. Previously, it was assumed that all child items in a Group have a name, which is not the case for list format.
  • Sidre: Fixed Group method importConduitTreeExternal() to handle lists with unnamed members the same as importConduitTree().
  • Slic and Lumberjack: Add missing calls to flush() for parallel output log streams.

Deprecated

  • Integer types in src/axom/core/Types.hpp are deprecated because c++11 supports their equivalents.
