README

sim-buddy

**Drive local CAE, CFD, and FEA tools from a desktop AI assistant.**

sim-buddy is a WorkBuddy / CodeBuddy plugin marketplace that lets an AI agent call the local [`sim` CLI](https://github.com/svd-ai-lab/sim-cli) and operate engineering simulation software on your machine.

For Simplified Chinese docs, see [README.zh-CN.md](README.zh-CN.md).

Plugins

**Tier 1 — installed by default:**

Plugin	Solver	License
`sim-comsol`	COMSOL Multiphysics	Commercial (offline `.mph` inspection works without COMSOL)
`sim-openfoam`	OpenFOAM	Open source (GPL); supports local or remote sim-server
`sim-ltspice`	LTspice	ADI freeware (free for personal use)
`sim-installer`	meta — teaches the agent how to install more solvers	—

**Tier 2 — opt-in (ask the agent or run the magic incantation below):**

Plugin	Solver	Notes
`sim-matlab`	MATLAB / Simulink	needs MATLAB on the machine (matlabengine links at install time)
`sim-abaqus`	Abaqus	needs Abaqus to run
`sim-fluent`	Ansys Fluent	pulls `ansys-fluent-core` (~100MB); needs Ansys + Fluent
`sim-hfss`	Ansys HFSS	pulls `pyaedt` (~100MB); needs Ansys AEDT
`sim-mechanical`	Ansys Mechanical	pulls `ansys-mechanical-core`; needs Mechanical
`sim-simscale`	SimScale cloud CAE	needs SimScale API key, no local CAE software
`sim-workbench`	Ansys Workbench	pulls `ansys-workbench-core`; needs Workbench

How It Works

You describe an engineering task
    |
    v
WorkBuddy / CodeBuddy loads the sim-buddy marketplace
    |
    v
The matching plugin SKILL shells out to the local sim CLI
    |
    v
sim CLI loads the installed driver (sim-plugin-)
    |
    v
The solver runs locally and returns artifacts/results
