SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

FluidSim provides a high-performance, Python-based framework for performing computational fluid dynamics (CFD) simulations using pseudospectral methods. It enables scalable solvers (2D/3D Navier–Stokes, shallow water, stratified flows) with MPI parallelization, streamlined parameter configuration, and integrated post-processing to analyze outputs.

Core Features & Use Cases

  • High-performance pseudospectral CFD solvers with MPI parallelization
  • Comprehensive workflow: parameter configuration, simulation execution, and post-processing
  • Supports 2D/3D Navier–Stokes, stratified flows, and shallow water with multiple solvers

Quick Start

Configure parameters with the default parameter set, instantiate FluidSim's solver, and start the time stepping to run a CFD simulation.
