The sea moves for two reasons: the Moon and the Sun raise the tide, and the wind builds the swell. This section explains both, and the computing methods used to design a machine that works with them.
- Tides: why the sea rises and falls twice a day.
- Swell and its energy: where waves come from and how much they carry.
- Simulation: FEM and SPH: how a machine is tested before it is built.
