Moving Day, Webinars, and Meetings

!!! Website Changeover: March 2 !!! will point to a new location beginning March 2. Look for the change midday. Don’t worry, the old website that has served us well since 2013 will not be retired completely but just be located at a different subdomain,

Software Developer’s Workshop: February 28 - March 1, March 4

It is not too late to join the discussion next week on updating CIG Best Practices and new technologies at our annual Software Developers Workshop. Our annual software meeting will be held over 2 half-days with an optional 3rd day for community members to organize working groups around topics of interests. If you develop code or are just interested in making software better, join us for presentations and discussions on software best practices and new technologies. A draft agenda is now available online. [register][agenda]

CIG Speaker Nominations - deadline February 28

CIG’s Distinguished Speaker’s program is entering its 5th year. In the past 4 years, speakers have engaged with 21 colleges and universities, visiting 10 MSIs and 4 EPSCOR states. Help us increase awareness of computational modeling and geodynamics by nominating speakers with exceptional capability to communicate our science. Deadline: February 28 . Mail your nominations to: [more info]

Webinar: March 10 @2p PT - Ryan Orvedahl**

Our next CIG Webinar features CIG Postdoc Ryan Orvedahl:

Dynamo Simulations of Planetary Cores
The majority of solar system planets possess global, or large-scale, magnetic fields. These magnetic fields are all thought to be generated by the dynamo mechanism, whereby kinetic energy associated with a convectively stirred plasma is converted into electromagnetic energy. Most planets have a large-scale magnetic field that is aligned with its rotation axis and often are characterized by a relatively strong dipolar component. In this work, large-scale magnetic field properties are investigated using rapidly rotating numerical simulations in a sphere. The large-scale magnetic field saturates as the intensity of convective motions is increased. The saturation is explored over a wide range of system parameters and is found to be a robust feature of rapidly rotating dynamo simulations. These results are described using a semi-magnetostrophic force balance, where the Lorentz force enters the leading-order mean force balance in only a single component direction. These simulations are generated using the Rayleigh pseudo-spectral code and current software development plans for its improvement will also be discussed.


2022 ASPECT Hackathon - Applications open

Applications are now open for this year’s ASPECT Hackathon May 15-24, 2022.

Due to COVID-19 and the layout of the venue, we will be able to accommodate fewer participants than previous years. The 2022 hackathon will focus more on the development of foundational features and the core of ASPECT, and less on supporting individual models and simulations as we have in the past. Consequently, applicants should have intermediate to advanced experience in the development of ASPECT. [more info]
