Summary of results
======================

The discretization is strong since it is about 45 knots per wavelength. This is why we obtain highly accurate results: the pressure calculated at the least favorable point differs from the theoretical value by less than 1%, for all three formulations: :math:`(u,p)`, :math:`(u,p,\phi )` and :math:`(u,\psi )`.

It should also be noted that all the models used give identical results.
