[CIG-SHORT] Intermediate Results

[BOK10 at pitt.edu]

Hi Charles,

I'm not running in parallel (I couldn't get the model to process in
parallel on the cluster). Each time step takes ~80 minutes with loose
tolerances, and about 2 hours for tighter tolerances.

The mesh itself is about 6,000 cells (2D). The faults have a 2 km
discretization, and the boundaries have a 5 km discretization. Im using
elasticplanestrain.
