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.) 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. Anyway, gorgeous visualisation!
