Is the COMSOL Sim skill free?

Yes. The skill itself is free from svd-ai-lab/sim-plugin-comsol. SkillProof publishes the install command and an independent test verdict at no cost.

What is the COMSOL Sim SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install COMSOL Sim?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use COMSOL Sim with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Works with setup
Score: 9.6/10
Tested: Jul 14, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 513385b

Built a synthetic .mph ZIP fixture from scratch and ran the skill's bundled inspect_mph() against it cold: it correctly pulled physics, solve status, and both Global Parameters straight out of the raw ZIP with zero JVM, exactly as the docs claim -- but that's the one path in this skill that needs no external software; everything else needs a real licensed COMSOL install plus the separate sim-cli tool.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

What COMSOL Sim does

Routes an AI coding agent to the correct real COMSOL Multiphysics control path -- offline `.mph` archive inspection, local COMSOL doc search, direct `comsolbatch`/`comsolcompile` execution, or a live `comsolmphserver` Java-API session -- for building, running, or debugging COMSOL models. Triggers when a user asks a coding agent to build, inspect, run, or debug a COMSOL/COMSOL Desktop model, and explicitly excludes generic COMSOL theory questions.

How to install COMSOL Sim

git clone https://github.com/svd-ai-lab/sim-plugin-comsol
cd sim-plugin-comsol
mkdir -p ~/.claude/skills
cp -r src/sim_plugin_comsol/_skills/comsol ~/.claude/skills/comsol-sim

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger COMSOL Sim

/comsol-sim Routes agents to the right real COMSOL control path -- offline, batch, or live session.

It also activates on plain-language prompts like these:

Help me build a COMSOL model of heat transfer through a metal block
Debug why my comsolbatch run isn't producing any output
I have a saved .mph file, tell me what physics it uses without opening COMSOL
