What problem does it solve?

FluidSim helps researchers run high-performance fluid dynamics simulations without building a custom CFD workflow from scratch. It unifies solver setup, execution, checkpointing, and post-processing for periodic-domain flow problems.

Core Features & Use Cases

  • Core solvers: Supports two- and three-dimensional Navier-Stokes, stratified flows, shallow water equations, and elastic-plate dynamics.
  • Research workflows: Handles turbulence studies, vortex dynamics, geophysical flows, restarting from saved states, and cluster-scale parametric sweeps.
  • Built-in analysis: Produces physical fields, spectra, spatial means, and energy-budget outputs for direct inspection and plotting.
  • Use case: A researcher configures a Taylor-Green vortex or turbulence experiment, runs it locally or on MPI, then inspects the saved fields and spectra to interpret the results.

Quick Start

Ask the skill to configure a FluidSim solver for your flow problem, run the simulation with the desired resolution and physical parameters, and summarize the outputs and analysis steps in plain language.

FAQPage Schema
How do I run Navier-Stokes simulations for turbulence studies?

Running Navier-Stokes simulations for turbulence involves configuring an FFT-based pseudospectral solver with desired physical parameters, executing locally or via MPI, and inspecting saved fields and spectra to analyze turbulent fluid flow dynamics.

What is the best way to set up a CFD simulation for stratified flows?

Setting up CFD simulations for stratified flows requires hierarchical parameter configuration to define the solver, then executing the run and using built-in post-processing to output physical fields, spectra, and spatial means for direct fluid flow analysis.

Does this pseudospectral solver support MPI for cluster-scale parametric sweeps?

Yes, the pseudospectral solver supports MPI for cluster-scale parametric sweeps, allowing researchers to execute high-performance computational fluid dynamics simulations and restartable outputs across distributed computing environments.

Can I analyze vortex dynamics and shallow water equations in two and three dimensions?

Yes, you can analyze vortex dynamics and shallow water equations in both 2D and 3D. The built-in post-processing produces energy-budget outputs, physical fields, and spectra for interpreting these periodic-domain flow problems.

How do I restart a fluid dynamics simulation from a saved state?

To restart a fluid dynamics simulation from a saved state, use the restartable outputs feature to load the checkpointed data, allowing you to resume execution of your turbulence or geophysical flow experiment without losing progress.
