This workshop will focus on providing training in the use of the CIG PyLith software for quasi-static modeling of crustal deformation, with an emphasis on interseismic, coseismic, and postseismic deformation. The training will also include instruction in CUBIT/Trelis for creating finite-element meshes as input for PyLith and visualizing PyLith output using Paraview.
This three day workshop will be held Friday, June 17 - Sunday June 19 on the campus of UC Davis prior to the plenary meeting CIG '16.
Tutorial slides are posted on the PyLith Wiki (videos of the presentations will be posted here too).
About 50% of the time will be devoted to tutorial lectures with instructors providing background information and running examples. The other 50% of the time will be devoted to "tinker time" during which participants can run the examples at their own pace, develop their own simulations, and get help from the instructors.

Binary packages and the PyLith manual are available on the PyLith webpage. The manual has a troubleshooting section, and there are links to the cig-short mailing list where users can get assistance. We will be releasing PyLith v2.2.0 shortly before the workshop. We strongly recommend getting familiar with PyLith v2.1.0 as there will be very little difference between v2.1.0 and v2.2.0.
csimsoft has created their own version of CUBIT, called Trelis. Sandia National Laboratories continues to provide CUBIT releases to US government agencies.
Users can download a 30-day free trial version of Trelis from csimsoft. Registering for the free trial version can take several hours to a day before you can download the software. We will be using the CUBIT 15.1 and Trelis 16.0.2 for the tutorials.
ParaView is a GUI visualization tool discussed in the PyLith examples. Binaries are available for a wide variety of platforms on the ParaView website. Click on Download. Use version 5.0.1.
Please registered for this tutorial through the CIG '16 registration web page.
