Adding a new Skill should keep the complete skill directory together with
SKILL.md,metadata.jsonwhen available, upstream attribution, references, assets, and workflow scripts.
git clone https://github.com/Cai-aa/CAE-Agent-Hub.git
Set-Location .\CAE-Agent-HubIf you cloned the repository before the rename, the old text-to-cae remote may still work through GitHub redirects. Updating the remote URL is clearer:
git remote set-url origin https://github.com/Cai-aa/CAE-Agent-Hub.gitEach adapter has its own dependencies and launch command; open its README from the table above. Install the required CAE application and confirm its license, then follow that adapter’s environment, dependency, and MCP registration steps. Install the in-application bridge where required.
Start with environment detection or a read-only model query, then run an example. Use a separate output directory and retain inputs, solver logs, and validation records.
Skills are instruction modules, not solver binaries. Copy the complete skill directory into your agent's skill directory or attach the relevant SKILL.md as project context.
Codex example:
New-Item -ItemType Directory -Force -Path "$env:USERPROFILE\.codex\skills" | Out-Null
Copy-Item -Recurse -Force ".\Skill\abaqus\analysis\abaqus-static-analysis" "$env:USERPROFILE\.codex\skills\abaqus-static-analysis"Suggested prompt:
Use the abaqus-static-analysis, abaqus-mesh, abaqus-job, and abaqus-odb skills. Check the Abaqus environment and inspect the current session first. Build a cantilever static-analysis case in a separate directory, mesh and solve it, extract ODB results, check force balance, and report the actual files, commands, and incomplete checks.
The viewer is still included as the browser result-inspection layer. It can display cases that contain result_mesh.json even when the solver is not installed.
Set-Location .\viewer
npm.cmd install
npm.cmd run devOpen the Vite URL, usually:
http://127.0.0.1:4178/
Run the viewer as above, then open the Peridigm entry at /peridigm.html. Choose either demo:
/peridigm.html?demo=elastic— two-point elastic verification: 6 actual frames, source gold and an independent oscillator comparison./peridigm.html?demo=fracture— precracked tensile damage demonstration: 3,200 material points, 31 actual display frames and independently reconstructed bond failure.
Replay requires neither Peridigm nor SSH. npm run build bundles both datasets for static hosting. These are recorded verified results, not a browser solver or a connected AI service. New solves use the Peridigm CLI/MCP and its Skill. See demo provenance and limits.

The repository should include reusable source, documentation, tests, examples, templates, and skill instructions. Curated public replay fixtures under models/peridigm-* are an explicit exception to excluding generated run data: they include only selected fields, verified summaries, canonical inputs and hashes, with attribution and capability limits. Full native jobs and private runtime state stay outside the repository.
It should not include:
- CAE software binaries or licenses.
- Private machine paths or credentials.
- Virtual environments and package caches.
- Raw solver outputs such as ODB, case/data, AEDT results, Workbench projects, and runtime logs.
- Large local result artifacts that can be regenerated.
Curated documentation images may live in assets/readme/ with provenance, case definitions, and scope notes.
Build the frontend viewer:
Set-Location .\viewer
npm.cmd run buildThe hub is designed to grow toward more mainstream simulation ecosystems:
- More solver-specific MCP servers.
- More productized skill packs for repeatable modeling and validation workflows.
- Shared result export formats for viewer and report generation.
- Safer install prompts and verification scripts for each CAE application.
When extending the hub:
- Keep reusable source code and workflow instructions together.
- Provide examples and tests where appropriate.
- Provide a README for the new component.
- Keep private paths, credentials, licenses, virtual environments, and generated solver results out of source control.
- Follow the existing repository structure and naming conventions.
- For Skills, preserve the complete
SKILL.md-based workflow and supporting references/assets.
This repository is released under the MIT License. See LICENSE for details.
The Peridigm module adds a shared CLI/MCP workflow, confirmed specifications, bounded repair and material-point viewer export. Qualified profiles cover two-point elastic code verification and a synthetic precracked tensile damage demonstration. Engineering strength and experimental accuracy remain unverified.
