sim

sim-cli lets Codex, Claude Code, GitHub Copilot, Gemini, and other coding agents drive CAE workflows through solver-specific plugins and bundled skills. The normal loop is:

check readiness -> attach to a session -> inspect state -> run one bounded step -> verify -> save artifacts.

Start with a solver plugin

Pick the solver you want an AI coding agent to operate.

• COMSOL Multiphysics
• Abaqus
• Ansys Workbench
• Ansys Mechanical
• Autodesk Fusion 360
• All solver plugins

Start with an agent

• Codex + COMSOL
• Codex + Abaqus
• Codex + Ansys Workbench
• Claude Code + COMSOL
• Claude Code + Abaqus
• Skill installation

First run

Install the runtime and one solver plugin, sync the bundled skill, then run a health check:

uv add sim-cli-core sim-plugin-comsol
uv run sim plugin sync-skills --target .agents/skills --copy   # Codex
uv run sim plugin sync-skills --target .claude/skills --copy   # Claude Code
uv run sim check comsol
uv run sim plugin doctor comsol --deep

How sim-cli works

• Why CLI-first, not MCP-first?
• Security and solver licenses
