conatus.expert.shell_floquet(solver, period, steps, *, m, n_modes=6, t0=0.0, fields=('u',), tol=REQUIRED, ncv=None, seed=0, max_iterations=None)

Floquet exponents of azimuthal wavenumber m of a linear period-period shell IVP (module doc): the n_modes multipliers of largest modulus of the discrete one-period map (steps steps of solver from t0; dt = period / steps required).

Parameters:

• period (float)

• steps (int)

• m (int)

• n_modes (int)

• t0 (float)

• fields (tuple[str, ...])

• tol (float)

• ncv (int | None)

• seed (int)

• max_iterations (int | None)

Return type:
