Versions

1.0.4.827 (Jul. 7, 2026)

Compatibility

Tested with Rhino 8.27 (RhinoCommon/Grasshopper 8.27.26019.16021). It might work with newer Rhino versions but they are untested. It does not work with Rhino 7 due to incompatibility issues introduced by McNeel (see below). If you need to downgrade or upgrade, please check the bottom of this page for specific Rhino download links.

Changelog

1.0.6-beta.827 (July 12, 2026)

Pre-release — install by ticking Include pre-releases in the Rhino Package Manager.

  • Added:

    • blueCFD install-path check: if blueCFD-Core 2024 is installed in a folder with spaces in the name (e.g. C:\Program Files\...), Eddy3D now warns everywhere the engine is used — the Install Engines component flags it directly in its callout (BlueCFD ⚠ spaces in path), in its status log, and on the Run components. Spaces break the OpenFOAM toolchain, so the UMF solver could never be built; previously this failed silently with "UMF Solver: Not Found". Install to a path like C:\blueCFD-Core\2024 instead.

  • Improved:

    • Check Geometry preview: display materials are cached per status color and mesh buffers are bulk-marshalled — smoother canvas on large models.

1.0.4.827 (July 7, 2026)

  • Fixed:
    • Outdoor / WSL: After a simulation on a machine without the Windows symbolic-link privilege (no admin rights / Developer Mode), the mesh link constant/polyMesh was unreadable from Windows — Explorer showed "The file cannot be accessed by the system" and ParaView reported the case "contains no meshes". Direction cases now provision the mesh as an NTFS directory junction (works without any privilege), and the Open In ParaView component repairs existing broken cases automatically.
    • Headless-safe BlueCFD environment setup and distro-aware WSL engine installation (Install Engines no longer assumes a hardcoded WSL distribution).
    • BlueCFD/UMF build environment on newer Windows 11 builds.
  • Improved:
    • Faster terrain vertex projection (batched into a single interop call).
    • Cached wind-comfort threshold tables to cut per-probe allocations, plus string/allocation optimizations across UTCI/PET, thermal comfort, and WSL command generation.
    • Progress dialogs: tooltips, word wrap, interactive hand cursor, and larger clickable areas for toggles and dropdowns.

1.0.2.827 (July 4, 2026)

First unified stable release of Eddy3D.

The previously separate plugins — wind (Outdoor), microclimate (Outdoor+ / urbanMicroclimateFoam), Indoor, MRT (Radiance/UTCI), and FluidX3D — are merged into a single Eddy3D package, available cross-platform on Windows and macOS (Rhino 8.27).

Install: via the Rhino Package Manager — run PackageManager in Rhino and search for Eddy3D. The standalone UMCF package has been retired.

  • Improved:

    • Show both OpenFOAM 12 and UMF install/reinstall toggles simultaneously in WSL mode.
    • Fetch and display accurate publish dates in the Yak version update prompt dialog.
    • Clean up custom Label UI intercept hacks to restore native GH component messages.

  • Fixed:

    • WSL OpenFOAM 12 repository URL (HTTPS to HTTP downgrade issue).
    • WSL bash grouping bug that falsely reported success on failed OpenFOAM installs.
    • UI logic bug in OpenFOAM 12 installation detection.
    • Generated Docker/shell scripts (e.g. run_docker.sh) shipped with Windows (CRLF) line endings, causing bad interpreter: /bin/bash^M on macOS. Scripts are now written with LF line endings.
    • The Select Template component now loads examples from the correct Eddy3D-Templates repository.
