The software package SeisSol (www.seissol.org) enables the simulation of complex problems in computational seismology with high-order accuracy on high-performance computing platforms. SeisSol has excellent potential for a wide range of applications with high impact on society and industry, such as the simulation of induced earthquakes (by geothermal power plants or CO2 storage processes, e.g.) and physics-based seismic hazard assessment.A particularly successful use-case is the multi-physics simulation of the non-linear dynamic rupture process of earthquakes coupled to the resulting seismic wave propagation in geometrically complex, highly detailed models -- such as the 2004 Sumatra-Andaman Megathrust Earthquake.In 2015, SeisSol has been released as an open-source project (github.com/SeisSol).While several pilot users have taken up the software, the following three issues have been identified to hinder a widespread adoption of SeisSol by Earth scientists:(1) Generating suitable unified geometric (CAD) model representations and high-quality discretisation meshes for SeisSol is, in general, a challenging task, which only recently became feasible.(2) While SeisSol is available as open-source (incl. a versatile software infrastructure and documentation), it still lacks installation support, tutorials and usage examples that guide potential users which are in general not highly experienced in high performance computing approaches. (3) For a widespread acceptance of SeisSol in the community it needs to provide an open platform to host reproducible simulation scenarios -- from established benchmarks for code validation, successful implementation of specific modelling requirements to production-ready scenarios allowing on-demand urgent simulations.In this project, we want to tackle all three roadblocks:(1) Provide a well-documented workflow to generate meshes of complex Earth structures, using commercial and open-source CAD and meshing software.(2) Establish training material and (face-to-face and online) introduction courses for potential users in the Computational Seismology community. (3) Design and install an infrastructure that maintains a wide range of reproducible simulation scenarios, ranging from benchmark simulations for constant software validation to scenarios that allow production runs for seismic hazard assessment. The best practices we will establish are of particular interest for supercomputing centres, which currently lack procedures for maintaining simulation software together with model scenarios and input data for real-time computation.

软件包SEISSOL（www.seissol.org）可以在高性能计算平台上使用高阶精度来模拟计算地震学中的复杂问题。 Seissol具有极大的潜力，可以对社会和行业产生重大影响，例如诱发地震的模拟（通过地热发电厂或CO2存储过程，例如）以及基于物理的地震危险评估。A特别成功的用例尤其是成功的用例。详细的模型 - 例如2004年苏门答腊 - 安达曼大型地震。通常，Seissol的网格是一项具有挑战性的任务，直到最近才变得可行。（2）虽然Seissol可以作为开源（包括。它是一种多功能软件基础架构和文档），它仍然缺乏安装支持，教程和用法示例，这些示例指导潜在用户通常在高性能计算方法中没有经验丰富。 (3) For a widespread acceptance of SeisSol in the community it needs to provide an open platform to host reproducible simulation scenarios -- from established benchmarks for code validation, successful implementation of specific modelling requirements to production-ready scenarios allowing on-demand urgent simulations.In this project, we want to tackle all three roadblocks:(1) Provide a well-documented workflow to generate meshes of complex Earth structures, using commercial and （2）为计算地震学社区中的潜在用户建立培训材料和（面对面和在线）介绍课程。 （3）设计和安装一个基础架构，该基础架构维护各种可再现的模拟方案，从用于恒定软件验证的基准模拟到允许生产进行地震危害评估的场景。我们将建立的最佳实践对于超级计算中心特别感兴趣，这些中心目前缺乏维护仿真软件以及用于实时计算的模型方案和输入数据的程序。
