Dynamically Adaptive Simulation of Tsunamis

In this talk/poster we present our framework for the simulation of tsunamis. The associated shallow water equations, a nonlinear hyperbolic system of conservation laws with an optional source term, i.e. including bathymetry or friction laws, are solved using state-of-the-art Riemann solvers. The integration of high-order Discontinuous Galerkin schemes is work in progress.

The talk/poster focusses especially on the viewpoint of computational science and highlights innovative concepts including dynamically adaptive triangular grid management and corresponding iterations using the space filling Sierpinski curve. In this context our parallelization strategy based on the Sierpinski curve is introduced as well.

The handling of large-scale block-adaptive geo information and an outlook to the coupling with dynamic rupture simulations of the Tohoku earthquake finalize the presentation.
