SeisSol#
SeisSol is a software package for simulating wave propagation and dynamic rupture based on the arbitrary high-order accurate derivative discontinuous Galerkin method (ADER-DG).
Characteristics of the SeisSol simulation software are:
use of arbitrarily high approximation order in time and space
use of tetrahedral meshes to approximate complex 3D model geometries (faults and topography) and rapid model generation
use of (an)isotropic elastic, viscoelastic, viscoplastic, and poroelastic material to approximate realistic geological subsurface properties
parallel geo-information input (ASAGI)
to produce reliable and sufficiently accurate synthetic seismograms or other seismological data sets
We gratefully acknowledge the funding of the German Research Foundation (as part of project no. 391134334 - “CoCoReCS”), which massively contributed to creating all documentation, tutorials, example workflows and reproducible setups published on this website.
