Workshop Agenda
Agenda for June 23-27 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)
- Generating the mesh in CUBIT (30 min)
- Running PyLith (30 min)
- Visualization of output using ParaView (15 min)

Monday - Intermediate Tutorials
These tutorials will provide a discussion of intermediate PyLith/CUBIT topics. Prior to the workshop users should have installed the software and worked through the examples provided in the PyLith manuals.
