The CIG Webinar Series draws from a pool of experts from mathematicians, to computer scientists, and to geoscientists, among others to bring together a cross-cutting community of faculty, students and researchers to both inform and disseminate knowledge on the tools and methodologies employed to further the study of problems in geodynamics.
Speakers in the 2017-18 webinar series Geodynamics in the Classroom share their approaches in teaching geodynamical modeling using a variety of tools including Python, MatLab, and Jupyter notebooks.
The one hour webinars will be held the 2nd Thursday of each month October through May. Webinars will be recorded for later viewing. Reminders and details will be sent out through the cig-all mailing list.

Students and young researchers who want to learn to use computational tools for geodynamic modeling have the option to choose among a wide range of numerical tools. I will show how Python and its libraries represent an easy-to-use platform for self-learning, with performance close to compiled codes. I will present (1) how to visualize and run vectorial calculations, (2) examples from classical Mechanics like particles trajectories in 2D-3D, (3) a detailed description of how to write Lagrangian, Eulerian and Particles in Cell codes for solving linear and non-linear continuum mechanics problems and (4) advanced techniques like tree-codes, Boundary Elements, Lattice Boltzmann Method, as well as use Jupyter Notebooks for creating and distributing content. The goal is to encourage professional and students to learn by experimenting and experiencing, like children who learn by playing.
Geodynamic modeling with staggered finite differences and marker in cell: theory, teaching and examples
Taras Gerya, ETH Zurich
Numerical modeling of geodynamic processes is an essential approach in both science and industry with ever- growing demand and high efficiency/cost ratio. Current trend in geodynamic modeling is to develop universal approaches with potentially unlimited number of applications.
One simple and flexible method is based on staggered finite differences and marker in cell techniques (SFD-MIC), which demonstrated superior performance in several branches of modern quantitative Earth sciences. It is suitable for modeling various long-term and short-term thermomechanical processes involving large 3D deformation of rheologically complex materials. Recently, potential applicability of this method to technological processes (material science) and natural processes of industrial significance (geo-hydro-mechanics, waste deposits) has also been demonstrated.
This webinar gives a short theory of the SFD-MIC method, discuses Matlab-based teaching approach and presents modeling examples of natural and technological significance. [slides]
