Today we are releasing our 2-D code for geodynamic simulations: the Simple Stokes solver with Exotic Rheologies, or SiStER. It is a MATLAB-based finite-difference / particle-in-cell code that solves for visco-elasto-plastic flow of geological materials. It is generally designed for long-term lithosphere and mantle deformation problems. SiStER is a great teaching tool to illustrate the various components of a modern geodynamic modeling code, but it can also be used for research applications (see for example our latest paper in this month's issue of GJI).
The code will be hosted on Github, in this repository, along with a brief code overview. I will take the lead in dealing with version control and incorporating updates, but external contributions are welcome!
Lastly, my colleagues and I have gotten support from CIG to teach a short course on modeling lithospheric deformation with SiStER at the 2016 GSA Meeting, this September in Denver. This is intended for non-modelers who are curious to learn about how geodynamic codes works, and what they can (and cannot!) do. Don't hesitate to get in touch if you would like some details... and see you in Colorado!
