Eddy3D not able to find BlueCFD - goes via Docker

Grasshopper Eddy3D

Eddy3D forces Docker even with BlueCFD installed — no way to switch engine

Setup:

  • Rhino 8, Grasshopper

  • Eddy3D v1.0.0008

  • BlueCFD-Core-2020 installed at C:\Program Files\blueCFD-Core-2020

  • OpenFOAM 8 confirmed working (simpleFoam -help runs correctly from BlueCFD terminal)

  • Docker Desktop installed (but I have very little familiarity with it)

Problem:

Every time I run a simulation, Eddy3D launches the Docker runner and fails:

Eddy3D Docker Runner
Image: pkastner/openfoam:8-umcf-4856041
failed to connect to the docker API at npipe:////./pipe/dockerDesktopLinuxEngine
Docker execution failed with exit code 1.

The install_engine_status_eddy3d.json correctly shows both Docker and BlueCFD as detected. The orange simulation component shows “Docker” in its footer and warns “Docker is selected but not installed.”

What I tried:

  • Connected C:\Program Files\blueCFD-Core-2020 to the CFDFolder input — no effect

  • Set "Installed": false for Docker in install_engine_status_eddy3d.json — no effect

  • Full uninstall and reinstall of Eddy3D — no effect

Question:

How do I switch the simulation engine from Docker to BlueCFD? There is no visible engine selector input on the simulation component, and no Settings component in the Eddy3D toolbar that exposes this option. Is there a config file, a hidden input, or a specific component I’m missing?
