FluidSim — настройка и анализ CFD-симуляций

★ 7.0 · engineering

fluidsim is a Claude Code skill that helps plan, configure, inspect, restart, and analyze FluidSim computational-fluid-dynamics simulations with explicit numerical-validity and HPC safety checks. It covers solver selection (including ns2d and ns3d), parameter review, FFT/MPI backend setup (fluidfft 0.4.5, pyFFTW 0.15.1, FFTW, PFFT, P3DFFT), output diagnostics, and restart compatibility. The required nine-step workflow runs from stating equations, boundary conditions, and acceptance criteria through preserving config, uv.lock, logs, and checksums — and never submits MPI jobs automatically. Designed for engineers and researchers working on pseudospectral Navier-Stokes simulations, turbulence analysis, and stratified or periodic flows on HPC clusters with Python 3.11+.
