[CIG-SHORT] 3 velocity BC

[Brad Aagaard]

Bobby,

I don't understand the description of what you are trying to do. Can you 
make a schematic diagram of your problem setup (geometry w/BC and 
faults) along with a mathematical description of what you want to 
calculate? For example, what components of displacement/velocity are 
constrained on each of your boundaries? Also, I don't understand what 
you mean by "solutions calculated across the middle boundary" and "only 
use the middle boundary to define a velocity in the center of the model"?

Regards,
Brad
