Seismic Simulations Using the ExaHyPE-Engine
Scientific Software Development
TimeTuesday, June 18th2:15pm - 2:45pm
DescriptionExaHyPE is a hyperbolic PDE engine for solving systems of first order hyperbolic PDEs written in a conservative or non-conservative form. In this talk, I present the current status of the ExaHyPE project in general and in particular the parallel capabilities of the engine. The project provides a space-tree discretization of the computational domain, various higher-order DG schemes and a-posteriori subcell limiters. This allows users to write only their own application specific code and benefit from the engines efficient adaptive mesh refinement algorithms and from the numerical schemes built into the engine.
The two main applications currently tackled with this engine are long-range seismic risk
assessment and the search for gravitational waves emitted by binary neutron stars. In this talk I will focus on the seismic simulations and show two methods that allow us to resolve complex geometry in spite of our reliance on cartesian meshes.
