When to use it

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.

Example requests

Ask your agent in plain language, for example:
  • “I need to run a 2D turbulence sim with fluidsim, 256x256 periodic box. Can you set it up safely?”
  • “I have a run in ~/runs/ns2d_forced_512/ with state_phys_t.nc files and spectra1D.h5. I tried params.time_stepping.CFL = 0.5 and got an AttributeError from ParamContainer when restarting with a modified script. I want to restart to t=200 on 8 MPI ranks on our cluster. What’s wrong and how do I restart safely?”*
  • “I’m simulating forced 3D homogeneous turbulence on a periodic cube in Python, and my collaborators want to know if our 128^3 spectral run is resolved enough to call it DNS. What should I check, and can you look at the output files?”

Install

In Claude Code you can also add the marketplace with /plugin marketplace add KalarisLabs/research-agent-skills and install the whole physical-sciences category with /plugin install physical-sciences@research-agent-skills.
