A tilted ocean surface is initialised in a realistic basin (the Cook strait area in New Zealand). The surface oscillates sending complex gravity waves reflecting off the coast and bathymetry (Figure 83). No explicit dissipation is added and Figure 84 illustrates the good conservation of the total energy.
This is a good test of the robustness of the method when dealing with adaptively refined complex bathymetry.
The robustness is controlled essentially by the way face-centred velocity values are computed from cell-centred values.
