Description

In this seminar we address numerical methods for hyperbolic partial differential equations. We discuss important examples of governing equations, with a special focus on the elastic wave equations (earthquakes) and shallow water equations (tsunamis). In this context challenges typical for hyperbolic PDEs are tackled: Non-linearities, Riemann solvers, dimensional splitting, high-order discretization, time stepping schemes, etc. Besides numerical theory a strong focus of the seminar is given by application and implementation of the learned concepts: all participants should demonstrate their presented methods and concepts via a small project, which requires extensive use of the learned theory.
