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.
