  3. Overall Goal: Compare the 3D methods currently being used by SCEC scientists to simulate (spontaneous) rupture dynamics Some Specific Objectives: *Understand if our methods are producing the same results when using the same assumptions about friction, crustal structure, fault geometry, etc. *Learn which methods are best suited for which type of problem, for example, dipping faults, complex friction formulations, heterogeneous materials. *Learn which methods might be best suited for coupling to simulations of longer times and larger regions. Sept. 11, 2005 SCEC Workshop

  4. This Workshop: • Learn about an in-depth code comparison • Learn about a new finite element code • Compare results of The Problem, Versions 4 and 5 • Learn about new IT ways to view our comparisons • Learn how our formats relate to the Ref. EQ database • Plan our next steps Sept. 11, 2005 SCEC Workshop
