Overview
fluidsim is an open-source data skill for Claude Code and compatible agents, published by K-Dense-AI. Its author describes it as: “Plan, configure, inspect, restart, and analyze bounded FluidSim computational-fluid-dynamics simulations with explicit numerical-validity and HPC safety checks. Use for FluidSim solver selection, parameter review, FFT…”. The project has 34k stars on GitHub and is available under the MIT license. Add it to your setup with `git clone https://github.com/K-Dense-AI/scientific-agent-skills ~/.claude/skills/fluidsim`.
What fluidsim does
Use FluidSim 0.9.0 as a framework for Python-defined numerical solvers, especially periodic Cartesian pseudospectral CFD. Upstream FluidSim is CeCILL-2.1; the MIT frontmatter license applies only to this skill.
What’s inside
The SKILL.md for fluidsim is organised into these sections:
- Required workflow
- Version and installation
- API snapshot
- Solvers
- Forcing and time advancement
- Outputs, loading, and restart
- Scientific acceptance gate
- Bundled local tools
- References
- Dated upstream basis
Installation
Add fluidsim to your agent with:
git clone https://github.com/K-Dense-AI/scientific-agent-skills ~/.claude/skills/fluidsimReview a skill’s source before installing it — skills can instruct your agent to run commands. This command comes from the skill’s public repository, which is the source of truth for setup steps. New to skills? Read how to install Claude Code skills.
Supported agents
Neither the skill nor its repository names a specific agent. It uses the SKILL.md format, which several agents can load — check the repository for any agent-specific requirements.

Frequently asked questions
- What does fluidsim do?
- Plan, configure, inspect, restart, and analyze bounded FluidSim computational-fluid-dynamics simulations with explicit numerical-validity and HPC safety checks. Use for FluidSim solver selection, parameter review, FFT/MPI setup, output diagnostics, or restart compatibility.
- How do I install fluidsim?
- Run git clone https://github.com/K-Dense-AI/scientific-agent-skills ~/.claude/skills/fluidsim in your agent, then reload your skills. Review the source at https://github.com/K-Dense-AI/scientific-agent-skills before installing.
- Is fluidsim free to use?
- Yes. fluidsim is free and open source under the MIT license, so you can read, run, and adapt it within that license's terms.
- Where does fluidsim come from?
- fluidsim ships inside K-Dense-AI/scientific-agent-skills, a repository that contains 42 catalogued skills in total. The repository's 33,821 GitHub stars apply to that whole collection, not to this skill on its own.
