项目摘要

Funding from this grant will support a two-year effort to develop code enhancements to the existing PyLith version 1.0 crustal dynamics modeling package. PyLith is currently maintained and supported through the NSF/EAR supported Computational Infrastructure for Geodynamics (CIG) facility but this support addresses code enhancements not currently targeted by CIG for future development. Enhancements will include: 1) coupling of quasi-static and dynamic solutions to allow for complete simulation of the earthquake cycle, including the dynamic rupture process; 2) development of nonlinear solvers to enable simulation of realistic crustal material behavior (e.g., viscoelastic, elastoplastic, elasto-viscoplastic); 3) automatic computation of gravitational prestresses; and 4) development of the capability to use a spherical mesh finite element framework for modeling the dynamics of large spatial areas. The work will involve no-cost collaborations with CIG funded personnel (Matt Knepley, Argonne National Lab), the USGS (Brad Aagaard) and a Caltech Ph.D. student. The code developments will be open-source and maintained in the CIG repository.
这笔资金将用于支持一项为期两年的工作,为现有的PyLith 1.0版地壳动力学建模包开发代码增强功能。 PyLith目前通过NSF/EAR支持的地球动力学计算基础设施(CIG)设施进行维护和支持,但这种支持解决了CIG目前未针对未来开发的代码增强。 增强功能将包括:1)耦合准静态和动态解,以允许完整模拟地震周期,包括动态破裂过程; 2)开发非线性解算器,以模拟现实的地壳材料行为(例如,粘弹性、弹塑性、弹粘塑性); 3)重力预应力的自动计算;以及4)开发使用球形网格有限元框架来模拟大空间区域的动力学的能力。 这项工作将涉及与CIG资助人员(阿贡国家实验室的Matt Knepley),美国地质勘探局(布拉德Aagaard)和加州理工学院博士的免费合作。学生. 代码开发将是开源的,并在CIG存储库中维护。
