Direct time integration schemes are an integral part of the FEM simulation of structural dynamics problems. Such schemes should be at least second‐order accurate, unconditionally stable, and numerically dissipates the high‐frequency components.

This paper focuses on the numerical approximation of the linearized shallow water equations using hybridizable discontinuous Galerkin (HDG) methods, leveraging the Hamiltonian structure of the evolution system. First, we propose an equivalent formulation

A discontinuous space-time Galerkin finite element method has been developed by the authors for the study of linear elasto-dynamic and fully coupled thermoelastic problems with discontinuities in the displacement and temperature gradients. The method is proven to be unconditionally stable and capable of automatic adaptive mesh refinement. The developed

Some hyperbolic systems are known to include implicit preservation of differential constraints: these are for example the time conservation of the curl or the divergence of a vector that appear as an implicit constraint.
