zoomy_core.fvm.legacy.projection_solver module

Chorin projection solver for incompressible Navier-Stokes.

Implements the pressure-correction scheme: 1. Predictor: advance momentum without pressure (explicit FVM) 2. Pressure Poisson: solve ∇²p = (1/Δt)∇·u* via iterative Jacobi 3. Corrector: u^{n+1} = u* - Δt * ∇p 4. Viscous step: u += Δt * ν * ∇²u (explicit diffusion)
