Wave Attractors on Enceladus

Enceladus, an enigmatic satellite. It orbits Saturn among many other moons, but the observations by Cassini of Enceladus were perhaps the most eagerly awaited. Enceladus did not disappoint: After Cassini's arrival in the Saturnian system interest has surged for this tiny moon. Many fascinating phenomena are taking place and Cassini has been...

Hamiltonian Discontinuous Galerkin Finite Element Method for Internal Gravity Waves: An exactly energy conserving discretization

A DGFEM discretization has been developed for the Hamiltonian dynamics of stratified incompressible linear fluid flow. The developed discretization can handle the numerical challenges posed by wave attractors: the three dimensionality of the domain, the focusing of wave energy and the incompressibility of the flow. The discretization is...
