What types of fluid simulations can FluidSim perform?

FluidSim supports a wide range of simulations including 2D and 3D Navier-Stokes equations, shallow water equations (sw1l), and stratified flows (ns2d.strat/ns3d.strat) using pseudospectral methods.

Does this skill support parallel computing for large-scale models?

Yes, FluidSim is designed for high-performance computing and supports MPI parallelization, allowing you to run high-resolution simulations across multiple processors or clusters.

Can I analyze simulation results directly within the tool?

Absolutely. FluidSim includes built-in post-processing capabilities to plot physical fields, spatial means, and 1D/2D energy spectra directly from the simulation output files.

What are the primary installation requirements?

FluidSim is installed via Python (uv or pip). For full functionality, it is recommended to install with the [fft] and [mpi] feature flags to enable spectral methods and parallel execution.
