fluidsim
Framework for computational fluid dynamics simulations using Python. Use when running fluid dynamics simulations including Navier-Stokes equations (2D/3D), shallow water equations, stratified flows, or when analyzing turbulence, vortex dynamics, or geophysical flows. Provides pseudospectral methods with FFT, HPC support, and comprehensive output analysis.

FluidSim is an object-oriented Python framework for high-performance computational fluid dynamics (CFD) simulations. It provides solvers for periodic-domain equations using pseudospectral methods with FFT, delivering performance comparable to Fortran/C++ while maintaining Python's ease of use. Key strengths: Multiple solvers: 2D/3D Navier-Stokes, shallow water, stratified flows High performance: Pythran/Transonic compilation, MPI parallelization Complete workflow: Parameter configuration, simulation execution, output analysis Interactive analysis: Python-based post-processing and visualization Install fluidsim using uv with appropriate feature flags: Set environment variables for output directories (optional): No API keys or authentication required. See references/installation.md for complete installation instructions and environment configuration. Standard workflow consists of five steps: Step 1: Import solver Step 2: Create and configure parameters Step 3: Instantiate simulation Step 4: Execute Step 5: Analyze results See references/simulationworkflow.md for complete examples, restarting simulations, and cluster deployment. Choose solver based on physical problem: 2D Navier-Stoke
