2014 CIG Crustal Deformation Modeling Workshop
Li Ka Shing Conference Center, Stanford University
Tutorials
A description of the software tools and general workflow used in crustal deformation modeling is available in the Short-Term Crustal Dynamics Work Area under General Information. Tutorials will cover the use of PyLith, CUBIT/Trelis, and ParaView. There will also be discussion of some other modeling tools during the Science Talks.

BEGINNER TUTORIALS
Beginner tutorials for PyLith and CUBIT/Trelis will not be offered at the workshop. Beginner users should work through the extensive set of examples in the PyLith manual and online tutorial.
THURSDAY JUNE, 12, 1:00PM - 3:00PM PDT: PYLITH/CUBIT INTRODUCTION AND HELP SESSION
This online help session will give new users a brief introduction to PyLith and CUBIT/Trelis and provide the opportunity to ask questions. This is intended to complement the use of the extensive documentation available via the PyLith user manual and online tutorials.
- Introduction to PyLith (60 min, slides, video [display problems; view slides w/video])
- Example: examples/3d/hex8/step03 (video)
