- Claude Code 2.x (agent harness)
Installed it the official way as well as by hand: uv add sim-cli-core sim-plugin-abaqus, then sim plugin doctor abaqus --deep came back OK on all five checks and sim plugin sync-skills copied the full skill tree into .claude/skills. Everything downstream of that needs a licensed Abaqus, which this machine does not have — sim check abaqus reported no installations detected, and sim run answered with a raw Python traceback rather than a clean message, so no job was ever solved here. The offline linter is real and does work, but it was a tie: sim lint passed both a cantilever deck I wrote cold and the skill's bundled snippet, so the solver-side value is unmeasured rather than disproven. The bundled known_issues.md is unusually candid, recording that the 4-element demo mesh returns 5.75e-6 m tip deflection against 2e-5 m analytical — exactly the calibration a cold run would get wrong.
Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works
- Installs cleanly 5/5
- Triggers reliably 5/5
- Output vs. baseline 5/10
- Docs & honesty 5/5
What Abaqus Sim does
Agent guidance plus a Python driver for running Abaqus input decks and Abaqus/CAE Python scripts through sim-cli — batch jobs, iterative noGUI CAE authoring sessions, job diagnostics, and artifact reporting. Triggers when you ask an agent to run, inspect, or debug an Abaqus model. Requires a user-owned, licensed Abaqus installation; the plugin ships no vendor binaries.
How to install Abaqus Sim
git clone https://github.com/svd-ai-lab/sim-plugin-abaqus.git
mkdir -p ~/.claude/skills
cd sim-plugin-abaqus && cp -r src/sim_plugin_abaqus/_skills/abaqus ~/.claude/skills/abaqus-sim
Skills live in ~/.claude/skills/ (global) or .claude/skills/
(per-project). Restart Claude Code after installing.
Commands — how to trigger Abaqus Sim
-
/abaqus-simDrives Abaqus FEA from an agent via sim-cli; needs your own licensed install
It also activates on plain-language prompts like these:
-
Write an Abaqus input deck for a steel cantilever with a tip load -
Run this Abaqus job and diagnose why the solver isn't converging -
Author a noGUI Abaqus/CAE Python script and check job diagnostics
Frequently asked questions
- Is the Abaqus Sim skill free?
- Yes. The skill itself is free from svd-ai-lab/sim-plugin-abaqus. SkillProof publishes the install command and an independent test verdict at no cost.
- Does Abaqus Sim work with Claude Code?
- We tested it with Claude Code 2.x (agent harness) on Aug 10, 2026. Verdict: Works with setup. Installed it the official way as well as by hand: uv add sim-cli-core sim-plugin-abaqus, then sim plugin doctor abaqus --deep came back OK on all five checks and sim plugin sync-skills copied the full skill tree into .claude/skills.

- What is the Abaqus Sim SkillProof Score?
- 8.0/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 5/10, docs & honesty 5/5.
- How do I install Abaqus 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 Abaqus 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.
