DESCRIPTION

F-wave Riemann solver for the one-dimensional shallow water equations.

Unlike the Roe solver, the f-wave solver decomposes the jump in fluxes (Δf = f(q_r) - f(q_l)) rather than the jump in quantities. The resulting waves Z_p = α_p · r_p are used directly as net-updates without additional scaling by the wave speeds.

DESCRIPTION

Unit tests for the f-wave Riemann solver.

Tests cover:

1. Eigenvalue computation for given input states.
2. Eigencoefficient computation (flux jump decomposition).
3. Steady-state: zero net-updates when q_l == q_r.
4. Dam-break scenario with symmetric setup (hu = 0).
5. Supersonic problems where one net-update is zero.
