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...
