Overview

This documentation is a collection of useful dynamic simulation examples to help users build models from scratch with little effort. Each example is demonstrated carefully with geometry building, parameter setup, and result visualization. Users are suggested to repeat each example in order to get a comprehensive idea of how to set up dynamic simulation models with SeisSol.

SeisSol is a part of SCEC dynamic code validation project (Harris et al. 2018) (http://scecdata.usc.edu/cvws/). Here we show several SCEC benchmarks for beginners to quickly catch up with SeisSol workflow. Each benchmark example is composed of a short problem description, a section of geometry, initial setups (stress, nucleation, friction, etc.), and simulation results.

Please note that the examples used here are only for demonstration purpose. For detailed benchmark tests please refer to SCEC benchmark center.

No. Fault type Difficulty Description
TPV5 strike-slip beginner slip-weakening and heterogeneous initial stress conditions
TPV6 strike-slip beginner bi-material fault and, slip-weakening and heterogeneous initial stress conditions
TPV12 normal fault beginner linear elastic and initial stress conditions are dependent on depth
TPV13 normal fault beginner non-associative Drucker-Prager plastic with yielding in shear ad initial stress conditions are dependent on depth
TPV16 strike-slip intermediate randomly-generated heterogeneous initial stress conditions
TPV24 branching strike-slip intermediate a rightward branch forming a 30 degree angle. There are linear elastic material properties
TPV29 strike-slip difficult stochastic roughness. Linear elastic material properties in a homogeneous half-space.
TPV104 strike-slip difficult Rate-state friction, using a slip law with strong rate-weakening.
Point Source strike-slip intermediate benchmark of SISMOWINE WP2_LOH1.
Kinematic reverse fault intermediate Kinematic source of 1994 Mw6.7 Northridge earthquake.

Prerequisites

Before you begin any of the examples, you will need to install the latest SeisSol from (https://github.com/SeisSol/SeisSol). The instruction can be found at https://seissol.readthedocs.io/en/latest/compilation.html. All geometry and tetrahedral meshes are generated using free software Gmsh (http://gmsh.info/). If you do not wish to create your own mesh at this time, the meshes are also provided as part of the example. The ParaView visualization package (https://www.paraview.org/) may be used to view simulation results. You may use other visualization software, but some adaptions from what is described here will be necessary. Furthermore, you can complete a subset of the example using files provided (as described below), skipping the steps for which you do not have the proper software packages installed.

Input file resources

The files needed to work through the examples are provided. All files necessary to set up the cookbook examples can be downloaded at https://gitlab.lrz.de/ru58zid/benchmarks/ (a backup repository will be: https://github.com/daisy20170101/SeisSol_Cookbook)
