[CIG-SHORT] Stress concentration near the fault tip

[Charles Williams]

Dear Josimar,

I am somewhat confused about your boundary conditions.  Are any conditions being placed on the top and bottom boundaries?  Also, it appears that you are applying Neumann BC on the left boundary, rather than the fixed displacement BC shown in your figure.  Is this correct, or is something mislabelled?

Cheers,
Charles
