Solving Hyperbolic PDE Systems with ExaHyPE

We present latest features and results for ExaHyPE, an engine to solve hyperbolic PDE systems. ExaHyPE employs high-order discontinuous Galerkin with ADER time stepping and a-posteriori Finite-Volume limiting. It builds on the Peano framework, which features tree-structured Cartesian meshes and shared- and distributed-memory parallelism using MPI and Intel TBB. ExaHyPE provides role-oriented code generation utilities that offer tailored views for application, algorithm and optimisation experts. Application experts can quickly realise solver via providing only PDE-specific implementation, such as for conservative fluxes, non-conservative products, source terms, etc. We present several use cases for the engine, partiocularly focusing on computational seismology. Here, we show results for a curvilinear model for seismic wave propagation and for a diffused interface model - both able to treat complex topographies with almost no effort on meshing.      «
