# Fluid Dynamics (CFD)

## Overview

Solve the Navier-Stokes equations for incompressible and compressible flows. Covers lid-driven cavity, channel flow, flow past obstacles, and turbulence analysis. For pseudospectral methods on periodic domains, also consider the `fluidsim` skill.

## When to Use

- Incompressible flow simulations (lid-driven cavity, channel flow, jets)
- Computing drag and lift on bodies
- Turbulence statistics (energy spectrum, Reynolds stresses)
- Vortex dynamics and wake analysis
- Flow visualization (streamlines, vorticity fields)
