What This Example Demonstrates

Validates the vorticity-stream solver against Ghia, Ghia & Shin (1982) benchmark data for lid-driven cavity flow at Re = 100.

Key Code Snippet

use cfd_2d::grid::StructuredGrid2D;
use cfd_2d::physics::vorticity_stream::{VorticityStreamConfig, VorticityStreamSolver};

let grid = StructuredGrid2D::<f64>::unit_square(41, 41)?;

let mut config = VorticityStreamConfig::<f64>::default();
config.base.convergence.max_iterations = 10000;
config.base.convergence.tolerance = 1e-6;

let mut solver = VorticityStreamSolver::new(config, &grid, 100.0); // Re = 100
solver.initialize_lid_driven_cavity(1.0)?;

for _ in 0..1000 { solver.step()?; }
