ExaHype2 is an open-source engine to solve hyperbolic partial differential equations. It is built on top of Peano 4, which provides the storage and traversal of the simulated domain in the form of a space tree. One of the most essential applications for ExaHype2 is the simulation of waves, which can be used for studying electromagnetism, earthquakes, and tsunamis. As the latter two often go hand in hand, it is useful to simulate them together to achieve a more accurate representation of the event. Since earthquakes are modeled as elastic waves, whereas tsunamis are modeled as acoustic waves, the need for solvers that can correctly model the interaction between the two mediums arises. In the paper "A high-order discontinuous Galerkin method for wave propagation through coupled elastic–acoustic media" such a solver was derived. The goal of this paper is to implement the solver in ExaHype2 and demonstrate its correctness with multiple test scenarios.     «
