Changelog

All notable changes to this project will be documented in this file.

The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

[Unreleased]

Added

  • Adds integral methods for PolyArea and subtypes of Domain with explicit tests for CartesianGrid, PolyArea, RegularGrid, SimpleMesh, and StructuredGrid.

Changed

  • Generalizes the alias functions (e.g. lineintegral) to also accept Domains.
  • Updated docstrings to improve clarity and consistency.

[0.16.3] - 2025-06-26

Changed

[0.16.2] - 2025-03-16

Added

  • Add official support for integrating over Frustum, Pyramid, and Wedge geometries (#168).

Changed

  • Improved unit testing with analytical solutions (#162, #166).
  • Made significant improvements to documentation (#165).
  • Updated compatibility entry for Meshes.jl to support v0.53 (#170, #171).
  • Updates several CI dependencies (#163, #167, #172).

[0.16.1] - 2024-12-29

Changed

  • Implemented a more efficient internal parametric transformation for Meshes.Tetrahedron, resulting in about an 80% integral performance improvement.

Fixed

  • Fixed a bug where integral would default to diff_method=AutoEnzyme() even when the Enzyme extension isn't loaded.

[0.16.0] - 2024-12-14

Added

  • Added a diff_method keyword argument to the integral API, allowing the user to specify which differentiation method should be used when calculating differential element magnitudes throughout the integration domain.
  • Implemented DifferentiationMethod types:
    • FiniteDifference for finite-difference approximation.
    • AutoEnzyme for using Enzyme.jl automatic differentiation (AD) via a package extension.
  • Added diff_method as an optional third argument to the jacobian and differential API.
  • Adds standardized support for integrating over Tetrahedron volumes.
  • Generalizes integrand functions to support any f::Any with a method defined for f(::Point).
  • Refactored specialization methods by implementing an internal _ParametricGeometry <: Meshes.Geometry to define geometries with custom parametric functions, standardizing support for BezierCurve, Line, Plane, Ray, Tetrahedron, and Triangle.
  • Significant performance improvements:
    • Achieved an 80x improvement when integrating over BezierCurve.
    • Achieved an up-to-4x improvement when integrating using HAdaptiveCubature.

Deprecated

  • Deprecated manual specification of GaussKronrod rules for surfaces, i.e. geometries where Meshes.paramdim(geometry) == 2. A warning is now generated recommending users switch to HAdaptiveCubature.

Fixed

  • Refactored the unit test system.
    • Standardized combinations.jl tests by constructing a TestableGeometry package and passing it to a @test generation function to provide more thorough and standardized test coverage.
    • Reorganized @testsnippets to exist in same source file as relevant tests.
    • Removed :extended tag from Tetrahedron now that performance is significantly improved.

[0.15.2] - 2024-10-25

MeshIntegrals.jl is now owned by the JuliaGeometry organization!

Added

  • Added a benchmarking suite using AirspeedVelocity.jl.
  • Implemented more unit tests with analytical solutions.

Changed

  • Tagged unit tests for Meshes.Box (4D) and Tetrahedron as :extended, removing them from automatic CI testing due to lengthy compute times.

[0.15.1] - 2024-10-11

Added

  • Adds official support and unit testing for integrating new Meshes.ParametrizedCurve geometries.

[0.15.0] - 2024-10-10

Added

  • Adds support for integrating geometries with any number of parametric dimensions by generalizing differential to n-dimensions via geometric algebra.
  • Adds official support and unit testing for integrating Meshes.Ellipsoid and Meshes.Hexahedron geometries.

Changed

  • Refactored the unit test system.
    • Completed transition away from previous @test generation system which only tested unit integrands (i.e. f(point) = 1.0) using Meshes.measure as a benchmark.
    • Used TestItems.jl to define independent @testitem packages, many with analytically-derived solutions.

[0.14.1] - 2024-10-04

Added

  • Adds official support and unit testing for integrating Meshes.Quadrangle geometries.

Changed

  • Continued work transitioning away from previous @test generation system.

Fixed

  • Fixed a bug in differential finite-difference approximation that may have reduced accuracy of some integral calculations.
  • Made improvements to type stability with floating point type keyword argument FP.

[0.14.0] - 2024-09-28

Changed

  • Rename IntegrationAlgorithm to IntegrationRule and consolidate terminology around integration rules (versus "algorithms", "settings", etc).
  • Convert floating point precision option FP from an optional argument to a keyword argument.
  • Continued work transitioning away from previous @test generation system.

Removed

  • Remove derivative and unitdirection functions. All derivative functionality was merged into jacobian.
