2006 Community Finite Element Models for Fault Systems and Tectonic Modeling

Monday

9:00am - 5:00pm

Tinker time Location: Classrooms 234/236, Student Center, 2nd floor

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.

RHEOLOGICAL ISSUES

To motivate from field and laboratory observations, as well as from theory, the primary rheological and geological issues that our modeling community should be concerned with over the next few years.

• What rheologies are needed to fully explain crustal deformation over the 1 to 100,000 year time scale?
• What type of modeling/observations is expected or needed to further constrain the models?
• What do these models tell us about the state of stress in the crust?
