This is very cool. I did my PhD in tidal interactions, but in the context of stars and giant planets - bodies that can typically be treated as having spheroidal symmetry. (In fact, one thing I was looking at was the corrections as you moved away from as assumption of spherical symmetry to include the equatorial bulge.)<p>The Earth's tides are far more complex because of the shape of the ocean basins, and it has quite a high dissipation rate. I'm not sure how much the internal tide contributes to that, but I suspect a lot given that the amplitude (tens of meters) is much greater than the surface displacement.<p>Anyway, gorgeous visualisation!
