SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

FluidSim helps you configure, run, and analyze computational fluid dynamics simulations without hand-building the full workflow each time. It reduces the friction of managing solver setup, time stepping, and output inspection for periodic-domain fluid models.

Core Features & Use Cases

  • Solver Selection: Work with 2D and 3D Navier-Stokes, stratified flows, shallow water, and related fluid models.
  • Simulation Workflow: Set hierarchical parameters, initialize states, run time stepping, and restart from saved checkpoints.
  • Analysis and Visualization: Inspect physical fields, spectra, spatial means, and performance logs after or during simulation.
  • Use Case: A researcher studying turbulence can configure a Navier-Stokes run, log gradient-like flow diagnostics, compare parameter sweeps, and review validation plots from saved outputs.

Quick Start

Use the fluidsim skill to configure a solver, run a simulation, and analyze the saved output files for fields, spectra, and spatial means.

FAQPage Schema
How do I set up and run a pseudospectral CFD simulation for periodic-domain turbulence?

You configure a pseudospectral CFD simulation by selecting a solver like 2D or 3D Navier-Stokes, defining hierarchical parameters, and running time stepping. The skill manages FFT-based execution for periodic-domain fluid flows.

Can I use MPI-compatible parallel runs for large-scale Navier-Stokes simulations?

Yes, the skill supports MPI-compatible parallel runs for Navier-Stokes simulations. It enables distributed execution across processors to handle large-scale turbulence and vortex dynamics computations efficiently.

What is the best way to analyze physical fields and spectra after a CFD run?

The best way to analyze physical fields and spectra after a CFD run is through the skill's built-in post-processing. It inspects saved output files to extract physical fields, spectra, spatial means, and performance logs for validation.

Does this approach support stratified flow and shallow-water solver scenarios?

Yes, this CFD approach supports stratified flow and shallow-water solver scenarios alongside 2D and 3D Navier-Stokes. It handles these solver-driven scenarios for turbulence, vortex dynamics, and geophysical flow modeling.

How do I handle checkpoint restarts when running fluid dynamics simulations?

You handle checkpoint restarts in fluid dynamics simulations by using the skill's checkpoint restart handling. It saves states during time stepping, allowing you to restart the simulation from saved checkpoints without losing progress.

What do I need to configure before starting a vortex dynamics parametric study?

Before starting a vortex dynamics parametric study, you need to select an appropriate solver and set hierarchical parameters. This setup initializes states for periodic-domain fluid flows required to run and compare simulation sweeps.
