Arxyne
Run engineering simulations from a conversation, on your own machine.
Arxyne dispatches a solver, records the run, and reads the result back. Eleven solvers ship: OpenFOAM, XLB and SU2 for aerodynamics, DoMINO as an ML surrogate, Chrono for vehicle dynamics, CalculiX for structures, Palace for electromagnetics, OpenCourant for crash, OpenLB and openCFS for acoustics, and Elmer for thermal multiphysics. Each run carries a record — the case, the container and its version — so a number can be recomputed later.
Install
In Claude Code:
/plugin install arxyne --marketplace arxynehq/arxyne-plugin
Then install the CLI, which the plugin calls. It is a separate install:
pip install arxyne
arxyne --version
Arxyne runs solver containers with Docker, so Docker must be installed and running. The first run of a solver pulls its image, which is large; a 2D case is the cheap way to start.
Use it
Ask for a simulation in plain language — a product, a solver and any settings you want to change:
- "Run Ahmed body on OpenFOAM and tell me the drag coefficient."
- "Which solvers can I use?"
- "Read back the results of my last run."
Claude calls your local arxyne MCP server. It can list solvers and
products, dispatch a run, and read results and provenance. Runs execute locally
in Docker and are stored under ~/.arxyne/. Nothing is sent to Arxyne: there is
no Arxyne account, no API key, and no service to reach.

Checks
A daily workflow (check.yml) validates the manifest and runs a live
handshake against the latest arxyne on PyPI, so a CLI change that breaks
the plugin's tools is caught here before it reaches a customer.
Data
The plugin sends nothing off your machine. Tool calls go to a local process
(arxyne mcp stdio); the CLI writes run records to ~/.arxyne/ and dispatches
Docker containers locally. Solver images are pulled from ghcr.io on first use,
which reveals to GitHub only that an image was fetched.
