[CIG-SHORT] Re: strike-slip benchmark results

[Jiangning Lu]

Hello, Greg

You might be right.  The strike slip GeoFest input files was generated
seperately by me, There must be somewhere different between Pylith and GeoFEST
inputs.., I used the Okada code posted on the CIG website to generate the
boundary conditon, so the boundary condition should be the same. The problem
probably comes from fault slip setting.
