PyLith Tutorial

12:00pm - 3:00pm

Tinker time

Dedicated time for installing software, including GeoFest, PyLith, LaGriT, etc. Code developers will be on hand to help you install these codes on your laptop. This is also a good time to try running example problems or benchmarks that are distributed with respective codes. This is also an opportunity for informal collaboration.
