Solver plugins

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

sim-cli-core is the runtime. Solver plugins add support for specific CAE and simulation tools. Each plugin only knows how to drive software the user already has installed and licensed on their own host — sim-cli does not bundle or redistribute commercial solvers or vendor SDKs.

All plugins below are Apache-2.0 open source.

Featured plugins

These are the plugins with active landing pages and end-to-end how-to guides. They’re the recommended starting set for COMSOL, Abaqus, Ansys Workbench, Ansys Mechanical, and Autodesk Fusion 360 work.

Plugin	Drives	Status	Add command	First how-to
`comsol`	COMSOL Multiphysics	Available	`uv add sim-cli-core sim-plugin-comsol`	Codex + COMSOL
`abaqus`	Dassault SIMULIA Abaqus	Available	`uv add sim-cli-core sim-plugin-abaqus`	Codex + Abaqus
`workbench`	Ansys Workbench	Available	`uv add sim-cli-core sim-plugin-workbench`	Codex + Workbench
`mechanical`	Ansys Mechanical	Available	`uv add sim-cli-core sim-plugin-mechanical`	Plugin page
`fusion360`	Autodesk Fusion 360	Git install (PyPI planned)	`uv add sim-cli-core "sim-plugin-fusion360 @ git+https://github.com/svd-ai-lab/sim-plugin-fusion360"`	Plugin page

After installing a plugin

check readiness → attach to live session → inspect model state
→ run one bounded CAE step → verify result/state → save checkpoint/artifacts

Sync the bundled per-solver skill into your agent harness with uv run sim plugin sync-skills — see skill installation for the .agents/skills vs .claude/skills choice.

Other plugins

A wider set of CAE, CAD, and simulation tools have plugins under development. See the plugin index for the full table.

If you’d like sim-cli to drive a simulator that’s not in the list above, the right channel is GitHub:

Propose a new solver: open a thread in sim-cli Discussions so others can chime in and signal demand.
Contribute code: open a PR against sim-cli or the relevant sim-plugin-<solver> repo.
