Session ID#: 13432

Session Description:
This session highlights the state of the art in computational solid Earth sciences. We solicit novel ideas on solving forward and inverse problems and their application to outstanding problems that push our understanding of the lithosphere-asthenosphere, mantle and core to new parameter regimes, resolutions, and multi-parameter systems.

This includes, but is not limited to modeling across the scales, coupling physics, novel inverse approaches, dealing with nonlinearities and uncertainties, effective media (e.g. homogenization), scaling implementations, open source community software, efficient usage of high-performance computing infrastructures, facilitating usage of novel data types, design of benchmark studies and best practices in software development and modeling.

By facilitating an exchange about the methods used for different applications, we aim to showcase the increasingly crucial role and impact taken by advanced computational methods in the Earth sciences, as well as sustainability and re-usability of their implementations.
